SDDC Business Networking

This section explains networking concepts that are important to understand when you use the SDDC platform.

Understanding Distributed vSwitches

Within ESXi, a Distributed vSwitch is a virtual switch, which is a logical construct that provides a link between uplinks and port groups. A vSwitch can use multiple uplinks and manage multiple port groups.

If a Distributed vSwitch uses two or more uplinks, a vNIC can only use one uplink at a time. For example, if you have two 1000 Gbps uplinks connected to the vSwitch and your VM connected to the port group connected to that vSwitch, the maximum theoretical bandwidth for that VM is 1000 Gbps, rather than 2000 Gbps.

By default SDDC Business is configured with two Distributed Switches:

ExNet - Private, customer-specific network segments usually representing VLANs hosted behind single tenant firewalls or load balancers.

ServiceNet- Backend network that most servers attach to with Rackspace-assigned 10.128.0.0/17 IPs used to reach internal services such as backup.

The following diagram illustrates virtual and physical networking components and their relationships to each other:

Adding a New Distributed vSwitch

Open the VMware vSphere Client or the VMware vSphere Web Client, and connect to the vCenter Server.
In the inventory panel, click on Networking.
Select the datacentre where you want to create the dvSwitch. Right-click on the datacenter and select New Distributed Switch from the context menu. This will open the New Distributed Switch wizard.
Name your DvSwitch, click Next.
Select the version, we recommend the latest. Click Next.
Configure the settings based on your requirements, click Next.
Review your setting, click Finish to start the DvSwitch creation.

Understanding Uplinks

An uplink is the physical interface between the hypervisor and the physical switch. An uplink is assigned to only one Distributed vSwitch. You can refer to an uplink as vmnicX, with X being a sequential number of a physical network ports on the hypervisor.

Understanding Port Groups

A port group is a logical construct on the Distributed vSwitch to which vNICs can connect. A port group typically has a name and a VLAN ID. One port group can serve multiple vNICs.

Understanding vNICs

A vNIC, or virtual network interface card, is a piece of the VM’s virtual hardware. A vNIC provides an interface for the OS and connects to a port group.There are multiple types of vNICs, such as E1000 or E1000E. We recommend using VMNXET3 for all VMs.

Adding a New Port Group

Open the VMware vSphere Client or the VMware vSphere Web Client, and connect to the vCenter Server that manages the dvSwitch you want to add the port group to.
In the inventory panel, click on Networking.
Select the dvSwitch you want to add the portgroup to.
Right-click on the dvSwitch and select Distributed Port Group then New Distributed Port Groups from the context menu. This will open the New Distributed Port Group wizard.
Provide a name for the port, click Next
Choose the VLAN type for the port group. You can choose VLAN to specify a specific VLAN ID, or None to create an untagged port group.
If you chose VLAN in the previous step, enter the VLAN ID for the port group.
Keep the rest of the settings as default, Click Next
Confirm the settings, click Finish to start the port group creation
Once the port group has been created, it will be listed under the dvSwitch in the inventory panel.
To add virtual machines to the port group, select the virtual machine you want to add to the port group, go to its Network Adapter settings, and select the port group from the drop-down menu.

SDDC Business Resource Pools

By default, the SDDC Business platform is configured with two resource pools:

SDDC Business Virtual Machines

Understanding VMware vCenter

VMware vCenter® is a centralized server used to manage your VM environment. Rackspace Technology Support also uses the VMware vCenter user interface to connect to and manage your ESXi hosts. SDDC Business offering provides access to VMware vCenter or a vSphere Client.

Understanding vCPU

A VM includes one or more virtual central processing units (vCPU). By allocating vCPUs to VMs, you can share physical CPUs on the hypervisor with the VMs.

Over-allocating CPU can negatively impact system performance. You should only allocate as many vCPU resources as your VM needs. If you allocate more cores than you need, you waste CPU cycles that could be used by your other VMs.

Understanding vRAM

You can allocate physical RAM on the hypervisor to the VMs as virtual RAM (vRAM). If you allocate more vRAM than is physically installed, application performance can suffer because of the techniques that ESXi uses to reclaim memory, such as memory swapping and memory ballooning. You should only allocate as many vRAM resources as your VM needs.

Working With Tags

Your VMware vCenter Server provides a feature called Tags that allows you to organize and categorize your virtual resources, such as virtual machines, templates, and virtual appliances. Tags can be used to group resources based on different criteria, such as department, application, or environment.

You can create and manage tags using the vSphere Web Client, which is the primary user interface for vCenter Server. To create a new tag, you can go to the Tags section of the vSphere Web Client and click on the “New Tag” button. You’ll then be prompted to enter a name and description for the tag, and to choose a category. You can also assign an icon to the tag to help differentiate it from other tags.

Once you’ve created a tag, you can apply it to one or more virtual resources. For example, you can go to the “Virtual Machines” section of the vSphere Web Client and select one or more virtual machines, then click on the “Actions” button and select “Assign Tag”. You’ll then be prompted to select the tag that you want to assign to the virtual machine(s).

You can also use the vSphere API to create and manage tags programmatically. The vSphere API provides a set of services and methods for creating, retrieving, updating, and deleting tags, as well as for working with other vCenter Server objects, such as virtual machines and datacenters. You can use one of the vSphere SDKs, such as the vSphere Management SDK, to interact with the vSphere API and automate various tasks related to vCenter Server.

You can also find vCenter tag automation using PowerCLI which is a PowerShell interface for managing vSphere environments. You can use PowerCLI to automate various tasks related to vCenter Server, including creating, modifying and deleting tags.

Creating a Tag Category

In your vCenter, click on Tags and Customer Attributes.
Click on Categories, New.
Provide a name, tags per object, and select the objects that the tag can be associated with.

The additional settings will likely be default, depending on use case:

VM Storage Policy

Use the drop-down box to select a Storage Policy. VSAN Storage Policies are used to align storage with application demands of virtual machines. It provides a storage policy framework that serves as a single unified control panel across a broad range of data services and storage solutions. Policies should already exist in order to assign a disk to them.

If Storage Polices are not in use, leave the setting as Datastore Default.

Disk Provisioning

Thin:
Virtual disks do not reserve space on the VMFS filesystem or on the back-end storage. They only consume blocks when data is written to disk from within the Guest OS. The amount of actual space consumed by the VMDK starts out small, but grows in size as the Guest OS commits more I/O to disk, up to a maximum size set at VMDK creation time.

Thick Lazy Zeroed:
Virtual disks reserve space on the VMFS filesystem but disk blocks are only used on the back-end array when they get written to inside in the Guest OS.

Thick Eager Zeroed:
Virtual disks have all space allocated and wiped clean of any previous contents on the physical media at creation time. May take longer during creation compared to other formats. The entire disk space is reserved and unavailable for use by other virtual machines.

Review the vdisk settings and click OK to save the virtual machine's settings. Ensure that the change has been applied successfully.

Power on the virtual machine, if it's not already powered on.
In the guest operating system of the virtual machine, use disk management tools to partition and format the new vdisk as needed.

SDDC Business Storage

This section explains the following storage concepts that are important to understand when you use SDDC Business.

Please note: vSAN is not supported as storage for SDDC Business. SDDC Business can consume shared block/file and dedicated block/file storage.
- Logical Unit Number (LUN): A LUN identifies a storage device. In the context of VMware, a LUN provides a foundation for a VMware filesystem (VMFS) datastore, or you can use it as an RDM (Raw Device Mapping).
- Datastore: A datastore is a volume formatted with a VMFS. You can create a VMFS datastore on top of a LUN or on a local RAID array. A VMFS datastore contains log files or files that comprise VMs.
- vDisk: A vDisk is a virtual disk. A Guest OS in the VM uses a vDisk in the same way it would use a physical disk but represents the vDisk as a vmdk file on a VMFS datastore.
The following graphic illustrates VMs that are connected to vDisks of different sizes. The vDisks reside on a VMFS datastore with some of the datastore space reserved. The datastore is formatted on top of a LUN.

Raw Device Mapping: Raw Device Mapping (RDM) is a type of storage configuration where a LUN is mounted to the VM directly, bypassing the datastore layer. Bypassing the datastore layer means that the Guest OS in the VM can issue Small Computer System Interface (SCSI) commands directly to the LUN. This configuration is most commonly used with Microsoft clustering. However, using RDMs means you cannot use features such as snapshots or VM-level backups. Other operations, such as storage vMotion, might also become more complex.

The following image illustrates two clustered VMs using their own vDisks and sharing two raw device LUNs. The pointer files, which reside on the VMFS Datastores alongside the vDisks, act as a proxy between the LUNs and the VMs.

Virtual Machine Snapshots

A snapshot represents a point-in-time state of the VM. Snapshots are useful if you suspect a short-term rollback might be needed, such as before starting a software upgrade on your VM.

When you take a VM snapshot, a delta file is created for each vDisk, and all changes moving forward are written to the delta files. This operation happens in the background and is not exposed to the Guest OS.

The delta files can grow rapidly and without your awareness. If the delta files fill the datastore, your VM might pause, which can result in unexpected downtime. Monitor the free space on your datastores and delete all unneeded snapshots.

📘

Note:

As snapshot files grow, it can affect all virtual machines on the hypervisor. For this reason, we recommend keeping a snapshot for no longer than two days. Depending on the circumstances, you can delete snapshots within hours or days after being taken. When you delete the snapshot, the changes stored in the delta files are merged back onto the original vDisks. This operation can take a long time. You can also revert (roll back) to a snapshot, in which case the changes in the delta files are discarded.

Do not use a snapshot as a VM backup. VM replication is a better alternative for making and restoring backups.

Expand LUNs

If you have requested that we expand your vDisk or you have added VMs, we might recommend or require that you expand your shared storage. Expanding a LUN comes with an additional cost. After expanding the LUN, we often expand the partition located on top of the LUN. Most commonly, the partition is a VMFS datastore, or in the case of an RDM LUN, a partition in the Guest OS.

To request that we expand a LUN, contact your Rackspace Technology account team and provide the following information:

Datastore name (if the LUN is formatted as a VMFS datastore) or partition letter (if the LUN is presented as an RDM).

The gross amount or net usable amount of space you want to add.

Shrink Storage

We cannot shrink LUNs, datastores, RDMs, local RAID disks, or vDisks. However, we might be able to help you migrate your environment to smaller datastores, LUNs, or vDisks.

If you are underutilizing space and want to downsize (this is an uncommon requirement), contact your Rackspace Technology account team and provide the following information:

The smaller size of storage you want.

The name of the VM you want us to migrate.

Storage Reccomendation

We recommend that environments have a certain percentage of each VMFS datastore free at all times. The datastore overhead percentage depends on the total capacity of each datastore.

Refer to the following minimum recommended datastore overhead values:

For datastores with capacity up to 2048 GB, the overhead is 15%.

For datastores with capacity between 2049 GB and 4096 GB, the overhead is 10%.

For datastores with capacity greater than 4096 GB, the overhead is 7%.

We recommend datastore overhead for the following reasons:

Some files and features (for example, snapshots, including snapshots made automatically by VM recovery) might consume datastore space rapidly and without your awareness.

If a datastore runs out of free space, it can cause downtime. A VM’s performance can be negatively impacted when the datastore is critically low on space.

Certain VMware features, such as snapshots, might no longer function without sufficient datastore space.

Powered-on VMs have a vSwap file equivalent in size to the amount of vRAM assigned to the VM. For example, a VM with 128 GB of RAM has a 128 GB vSwap file. vSwap files only exist for VMs that are powered on. Powering on a VM or increasing the amount of vRAM in your VM consumes additional space on the datastore.

A VM might not power on due to insufficient space on the datastore.

All VM log files are stored within the VM container folder on the datastore. A typical log file is a few MB in size; however, log files can grow to a few GB in size depending on VM activity and DRS migrations.

SDDC Busines Roles and Permissions

vCenter Roles and Permissions

To implement the separation of customer and Rackspace duties in SDDC Business, Rackspace uses built-in and custom roles in the vCenter Server. Rackspace assigns you a maximum permission role (customer role) and any lesser privileged roles that you request for specific users or groups.

Customers have permissions to create, delete, and manage VMs within their private cloud. Rackspace manages and maintains the ESXi hosts, the vCenter Server, Jump and SVS servers, and additional management VMs as required by the SDDC Business solution. Customers therefore have limited permissions on hosts and management servers.

Specific resource pools and folders are created to house customer created VMs and ensure separation from management VMs. In support of this separation, customers are granted permissions to create, delete, and manage VMs in the Compute-ResourcePool resource pool and in the Workloads and Templates virtual machine folders.

If required for organisational or resource management purposes, customers can create new resource pools below the Compute-ResourcePool and new folders below the Workloads and Templates VMs folders.

The following permission sets are predefined in the vCenter Server:

Customer Access

VM Power User

VM User

Read Only

Customer Access permission set is a product of permissions applied to two sets of roles. A lower permission set is enforced at the root of the inventory tree, and a higher permission set is applied at the resource pool level of the inventory tree.

The following table shows which vCenter Server permissions are available to each role.

Permission	Customer Access	VM Power User	VM User	Read Only

Authentication Methods

SDDC Business customers have two choices for vCenter authentication:

Rackspace-provided Active Directory service

Customer-provided Active Directory service

By default Rackspace is added to every SDDC Business environment at build time. This is to allow our support staff to assist our customer and for day two operations

To check the current authentication sources, click on the vSphere Client menu then click on Administration.

Click on configuration.

To add your Active Directory as an Identity source please raise a request with our support, the below information is required.

Configuration Item	Description
Name	Label for identification
Base DN for users	The Distinguished Name (DN) of the starting point for directory server searches.
Base distinguished name for Groups	The Distinguished Name (DN) of the starting point for directory server searches.
Domain Name	Your domain name. Example: “domain.local”
Domain Alias	Your NetBIOS name. Example: “Domain”
Username	Domain user with at least browse privileges. Example: “[email protected]”
Primary Server URL	ldap://ipaddress:3268
Secondary Server URL (Optional)	ldap://ipaddress:3268

Secondary Server URL (Optional) | ldap://ipaddress:3268 |

Maintain Your SDDC Environment

To reduce the risk of certain change requests, Rackspace Technology or customers can recommend that certain functions occur in a scheduled maintenance. These scheduled maintenances ensure that the following are available to the customer:

Reserved Rackspace Technology resources to complete the defined tasks of the maintenance.
Documented maintenance preparation and quality checks from all departments involved in the maintenance.
Defined length of maintenance to accomplish the defined tasks.
Documented rollback plan in the event of unforeseen circumstances during execution.

Because we cannot confirm the full scope of a maintenance until we completeall quality checks, Rackspace Technology schedules only after all quality checks have passed.

Because we base the maintenance calendar scheduling on availability of all teams involved, we accept reservations on a first-come, first-served basis. However, if this maintenance is urgent or if there is a limited timeline in which to execute it, contact your account team to see if we can accommodate your need.

vSphere Clusters

A VMware vSphere cluster is a collection of ESXi hypervisors that work together. vSphere cluster members pool their resources with a single VM that draws resources from one hypervisor at a time. All cluster members have either identical, or, in some cases similar, configurations.

By default, and to further benefit from the clustered setup, Rackspace Technology enables a Distributed Resource Scheduler and High Availability.

You can use vSphere portal to see the ESXi hosts that form a part of a vSphere cluster. If you have multiple vSphere clusters, you can see all of the clusters. Understanding the ESXi hosts that comprise a vSphere cluster is useful when you ask us to make changes to multiple ESXi hosts. Instead of providing us with he names of all hosts in the cluster, you can simply give us the vSphere cluster name.

To see vSphere clusters and members:

Log in to your environment.
Expand your vCenter and your virtual data center.

Distributed Resource Scheduler

Distributed Resource Scheduler (DRS) monitors the workload between hypervisors, and you can configure it to move VMs between ESXi hosts and address any imbalance automatically.

DRS operates in the following three modes:
- Fully automated (default, recommended): When you power on a VM, DRS moves running VMs and automatically selects the most suitable host.
- Partially automated: DRS automatically selects the most suitable host when you power on a VM but only provides recommendations to migrate running VMs.
- Manual: DRS provides recommendations for the initial placement of VMsand recommendations for running VMs but does not automatically migrate running VMs.
Because the vSphere Cluster uses workload to determine the placement of the VMs, the placement of VMs can appear random and not associated with your business requirements. To control VM placement, you can ask us to configure DRS rules.

Consider the following DRS rules categories:
- VM-VM Affinity: Keep VMs together. Use this affinity setting if VMs perform best when they run on the same host.
- VM-VM Anti-affinity: Keep VMs separate and prevent them from running on the same host. If you have two web servers running on the same host, and the host fails, both web servers go down.
- VM-Host rules: Host rules apply to a group of VMs and a group of hosts. Each group must include at least one member. Use the following options to define a VM-Host rule:
  - A group of VMs should run on a group of hosts. This approach limits some VMs to run only on a set of hosts. You might want this option due to a specific hardware (for example, greater capability) advantage on those hosts. However, the rule is ignored when you place eligible hosts in maintenance mode and during an HA restart.
  - A group of VMs must run on a group of hosts. VMs do not automatically migrate when you place all eligible hosts in maintenance mode. In addition, if no hosts in the defined group are available, HA might not restart the VMs.
  - A group of VMs should not run on a group of hosts. This rule is similar to the first VM-host rule, except that this rule defines the group of hosts that some VMs should avoid. For example, VMs are not placed in a group of hosts that are defined as part of the rule.
  - A group of VMs must not run on a group of hosts. The VMs avoid the specified hosts at all costs, even during an HA failover event.

High Availability

High Availability provides failover protection against hardware and operating system outages within your virtualized environment. High Availability allows you to:

Monitor VMware vSphere hosts and virtual machines to detect hardware and guest operating system failures.
Restart virtual machines on other vSphere hosts in the cluster without manual intervention when a server outage is detected.
Reduce application downtime by automatically restarting virtual machines upon detection of an operating system failure.

Licensing

All VMware licensing for RPC-VMware must be purchased from Rackspace. VMware licenses for SDDC Business are installed during provisioning.

Windows OS Licensing: You can provide your own Windows OS licenses or purchase a Windows Data Center license from Rackspace. If you purchase host-based OS licensing from Rackspace, it can be activated with the Rackspace Key Management Server (KMS). The Rackspace KMS server is accessible only by systems hosted with Rackspace. Contact your Rackspace Account Management team for more information.

Red Hat OS Licensing: You can provide your own Red Hat Enterprise Linux (RHEL) OS licenses or purchase a RHEL host-based license from Rackspace. If you purchase host-based OS licensing from Rackspace, it can be activated with the Rackspace Red Hat Network (RHN) server. The Rackspace RHN server is accessible only by systems hosted with Rackspace. Contact your Rackspace Account Management team for more information.

Applications Licensing: The customer must provide all application licensing.

ESXi-Patching

Subject to technical eligibility, or if you are running or at risk of running an unsupported ESXi version, we might proactively upgrade your hypervisor to a newer ESXi version. If we plan to proactively upgrade you, we notify you in accordance with the Dedicated Hosting Terms and Conditions.

We also work with you to perform VMware ESXi upgrades at your request or to address critical vulnerabilities.

Because your VMware Server Virtualization configuration can vary, we recommend reaching out to your account team to discuss upgrade options that best suit your environment and needs.

Upgrades

We offer major ESXi version upgrades for your ESXi hosts and minor patches, such as bug fixes and security updates. Depending on your configuration, upgrading your ESXi host might require downtime for some VMs. The upgrade might also negatively impact VM performance. Because system performance can be negatively impacted, we usually upgrade ESXi hosts during a planned maintenance window.

To upgrade your ESXi version, open a Rackspace Technology ticket and request an upgrade. If your environment is eligible for an automated upgrade, we contact you via a ticket and proceed with the upgrade.

If your ESXi version is close to or beyond the end-of-support date, we open a ticket and notify you that you should upgrade. If you do not respond to that ticket, and if your environment is eligible to be updated without shutting down VMs, we inform you of our plan and perform the upgrade.

Hardware Maintenance

Subject to compatibility, terms, and cost, we can perform routine hardware maintenance tasks on your hypervisor chassis, including upgrading firmware, managing the local RAID array, and replacing the battery.

To request maintenance, contact your Rackspace Technology account team. We complete chassis-related work during a planned maintenance window.

Capacity Planning

As your business grows and you add or expand your VMs, you might need to add more hypervisors to meet the demand.

Does the environment run well, or do you need additional physical resources to keep up with demand from the VMs?

What would happen if a hypervisor goes down?

What would happen if a hypervisor undergoes maintenance?

SDDC Business Monitoring

The platform infrastructure is monitored by existing Rackspace Monitoring solution. Nimbus for ESXi and Cloud Monitoring for vCenter and Backup.

SDDC Business Management Devices Backup

SDDC Business management components are backed up daily using an image-based backup solution and/or by using VMware-provided backup mechanisms for individual components.

📘
Note: Backups for VMs that the customer creates are not provided unless the optional Data Protection Service is purchased.

About vSphere Alarms

vSphere Alarms are a feature of VMware's vSphere virtualization platform that can help administrators proactively manage their virtual environment. These alarms are designed to monitor various aspects of the virtual infrastructure and notify administrators when certain conditions are met.

Here are some key points about vSphere Alarms:

vSphere alarms are based on user-defined thresholds and rules. Administrators can create alarms to monitor different types of events, such as host hardware failures, datastore space usage, virtual machine CPU usage, and more.
Alarms can be triggered by a variety of conditions, including specific events, performance thresholds, and status changes. When an alarm is triggered, vSphere will generate an alert that can be sent to administrators via email or other notification methods.
Administrators can configure the severity level of alarms, which determines the urgency of the notification. For example, a critical alarm might indicate an imminent hardware failure, while a warning alarm might indicate a less urgent issue that requires attention.
vSphere Alarms can be customized to meet the specific needs of an organization. Administrators can create alarms based on individual virtual machines, hosts, clusters, or datastores, and can configure different notification settings for each alarm.
vSphere Alarms can help administrators detect and resolve issues before they cause downtime or other problems. By monitoring the virtual infrastructure and proactively responding to alerts, administrators can ensure that the environment is running smoothly and efficiently
vSphere 7 alarms that are created at higher levels in the vSphere hierarchy will be propagated to the underlying objects at lower levels where applicable.

Creating a vSphere Alarm

Open the VMware vSphere Client or the VMware vSphere Web Client, and connect to the vCenter Server.
In the vSphere client, select an object in the inventory pane and navigate to Alarms, New Alarm Definition.
Provide a name for the alarm, a description, and a target type. Click Next
Define the alarm rules as desired. Click Next
Set the desired actions for alarm reset. Click Next
Review the alarm definition and click Create.
