No. We currently support only one cloud network per cloud server.
No. For each cloud server, we currently support:
- One cloud network
- One IP address per cloud network
- One public IP address network address translation (NAT) per cloud server
Not yet, but we are working on a migration path. Initially, we plan to offer you the ability to associate a new cloud account with your existing RackConnect v2.0 configuration, which will enable you to experience RackConnect v3.0 without deactivating your existing RackConnect v2.0 environment. Note that only cloud servers will be compatible with the migration process to RackConnect v3.0. We will provide more details about this process as they become available.
No. Because of access list limitations, we currently support the Brocade ADX 1000 devices only in the connected device role. For a full list of network devices that are compatible with RackConnect v3.0, see RackConnect network device comparison.
Yes, with few limitations.
- RackConnect v3 allows only one cloud network to be attached to the cloud server.
- RackConnect v3 allows you to attach IPv6 networks.
- Cloud Networks is not a dual stack, so you cannot create a cloud network that assigns IPv4 and IPv6 addresses on the same interface.
If you are starting fresh, configure the firewall to use an IPv6 address, assign an IPv6 IP block for the inside segment, and use that information to deploy a new RackConnect v3 vlan.
Using the preceding information, you can deploy a new RCV3 vlan with an IPv6 address to use on your cloud server.
Network devices in a Managed Colocation environment are supported only if the network devices are managed by the Rackspace Network Security team. Customer-managed network devices are not supported. For more details about RackConnect v3.0 compatibility with other Rackspace offerings, see RackConnect v3.0 compatibility.
The answer varies based on whether you are an existing Rackspace customer:
- If you are new to Rackspace, contact a member of our Sales team for help. For details about how to contact our Sales teams, go to Contact Rackspace.
- If you are an existing Rackspace cloud-only customer, contact a member of our Sales team for help. For details about how to contact our Sales team, go to Contact Rackspace.
- If you are an existing Rackspace dedicated-only customer, contact your account manager for help in getting RackConnect v3.0 set up in your environment.
Yes, but with the following caveats:
Note: Pre-existing cloud servers refers to cloud servers that were built before RackConnect v3.0 was associated with the cloud account.
- For the best possible experience, we recommend using a clean cloud account (meaning a cloud account with no pre-existing cloud servers) with RackConnect v3.0.
- If the pre-existing cloud servers use PublicNet, you must remove PublicNet before attempting to add a RackConnect v3.0 cloud network to the cloud server. If you are a Managed Operations customer and need help detaching PublicNet, contact your Rackspace support team for assistance.
- If the pre-existing cloud servers use ServiceNet, the ServiceNet IP address will change because ServiceNet will be detached and then re-attached to apply the appropriate security policies. Note that ServiceNet in RackConnect v3.0 is highly restricted and cannot be used for communication between cloud servers.
See the “Cloud Networks” section of RackConnect v3.0 limitations.
For the full list of requirements, see RackConnect v3.0 requirements.
Because RackConnect spans both your cloud and dedicated environments, you can contact your cloud or dedicated hosting support teams for help with RackConnect. If you are certain that the issue you are experiencing is directly related to your cloud servers, we recommend contacting your cloud hosting team first. However, if you are certain that the issue is related to your network device, we recommend contacting your dedicated hosting team first. For details about how to contact your support teams, visit the Contact Us page.
By default, when you use the Cloud Servers API or nova client to build
cloud servers, the servers are built with a PublicNet network. However,
RackConnect v3.0 does not support PublicNet and restricts you from
building cloud servers with PublicNet attached on RackConnect v3.0
linked cloud accounts. This restriction is likely the reason that you
403 Forbidden responses. Following are details for
resolving this error:
- When building a cloud server using the nova client
bootcommand, include the
--no-publicoption to prevent the PublicNet network from being attached to the server. Note that you can also use the
--no-service-netoption with the nova client
bootcommand to keep the ServiceNet network from being attached to a cloud server. However, consider that ServiceNet is required for cloud servers created in cloud accounts with a Managed Operations service level.
- With the Cloud Servers API, specify the cloud network that you want to attach to the cloud server. If you specify one or more networks, your server is attached to only those networks. For more information, see the Create your first Server section of the Cloud Servers v2 Developer Guide.
Customers with a dedicated account should speak to their Account Manager. Be aware that RackConnect is supported only where Rackspace cloud infrastructure exists. At this time, the Rackspace cloud is available from our Chicago, Dallas, Virginia, Sydney, Hong Kong, and London regions.
If you are an existing cloud customer, you should speak to a member of our Sales team. They can guide you through the process of acquiring a device that can be used in a RackConnected environment.
You need RackConnect to build a hybrid hosting solution that combines the best of dedicated and cloud hosting by creating connections between dedicated servers and cloud servers. RackConnect can be implemented on certain Cisco ASA series firewalls, or an F5 BIG-IP load balancer that is used to interconnect dedicated physical servers with cloud-based servers on the Rackspace internal network known as ServiceNet.
If you need help with RackConnect, contact us via any of our usual Support channels, and our team will help you with your issue or direct you on to the relevant support group. We are available via phone, chat, or tickets 24x7x365.
If you believe your issue is cloud-server specific, send the appropriate query to the Cloud team through the Cloud Control Panel; otherwise, send other requests through the MyRackspace Portal.
You may use RackConnect an existing cloud account, but you cannot connect to any existing cloud servers. If you need to use existing servers, they must be rebuilt after the RackConnect implementation has been completed. You can do this by first saving a cloud server image, and then using the image to rebuild the existing server as a new RackConnect server - or to simply build a new server.
Please be aware that this process for rebuilding an existing server assigns a new IP assigned to the server. Because you are essentially creating a new server, this cannot be avoided.
An important consideration is the region you will use to provision your servers. Because RackConnect relies on a ServiceNet connection to link your dedicated servers and your cloud servers, you must provision your RackConnect cloud servers in the same geographic region as your dedicated servers. Your saved server images are available only for creating servers in the same region as the original server.
You can use RackConnect with both Managed Operations service level and Managed Infrastructure service level accounts.
Be aware that the usual service-level limitations still apply for RackConnect cloud accounts, and you should use the appropriate account type for the implementation based on your support requirements. It is possible to use RackConnect with more than one cloud account, so you can have a mix of both if you prefer.
During normal circumstances, if your cloud account has been enabled with RackConnect v2.0, your cloud account is linked to your dedicated hosting account and your dedicated servers can communicate using ServiceNet with your cloud servers in the same region. If you want to provision cloud servers that are not linked to your dedicated account, use one of the following methods:
Provision cloud servers in a region other than the one where your dedicated servers are located. For example, if your dedicated servers are in the DFW region, and your linked cloud servers are also in the DFW region, any cloud servers you provision in ORD or IAD will not be linked to your dedicated servers and should function independently.
Sign up for a second cloud account. The drawback of doing this is that you cannot access any custom server images between accounts.
For cloud servers that are a part of your RackConnect configuration, all network traffic leaves via the dedicated firewall device. The traffic between the cloud servers and the RackConnect device travels over the internal, unmetered ServiceNet network. Any traffic between the cloud servers and dedicated networks is similarly unmetered and does not incur bandwidth charges.
The bandwidth usage costs for Internet-related traffic entering and leaving the RackConnect device is charged using Dedicated Hosting bandwidth pricing plans. Our Sales representatives will discuss this in more detail with you when you inquire about RackConnect.
RackConnect network policies are the equivalent of firewall rules that are applied via the RackConnect web interface. These policies are then applied to the firewall device and any cloud servers referenced.
The network policies are a useful means of centralizing all your firewall rules for the RackConnect device, any dedicated networks, and any RackConnect cloud servers.
Check the RackConnect network policies that are in place to ensure that the relevant access rules permit the required connectivity. For example, ensure that an Internet-to-Cloud rule exists to permit traffic originating from the Internet to reach your cloud servers.
If adjusting the network policies does not resolve the issue, contact Support via phone, chat, or ticket so that we can help investigate this further.
Yes, RackConnect cloud servers can be used to connect to Cloud Databases instances, but dedicated servers in a RackConnect configuration cannot connect to Cloud Databases instances.
No. Because RackConnect is intended to interconnect devices on a local network, any involved servers need to be within the same region.
If you have existing dedicated hardware, ensure that your cloud account is provisioned to build your cloud servers in the same region. Contact our Cloud support team for help with this. Rackspace has cloud infrastructure in Chicago, Dallas, and Virginia in the US, and global cloud infrastructure in London, Sydney, and Hong Kong.
Yes. Because RackConnect is a dedicated firewall, it is possible to terminate a site-to-site VPN on the device, or to use a client-based VPN. This enables secure VPN communication between your office or home into the cloud environment.
Most areas of our data centers have access to our ServiceNet network through which a customer can connect privately to our Cloud Files infrastructure without traversing the public network (provided the files are in the same data center as the dedicated server making the connection). The older areas of our DFW data center that do not have ServiceNet need RackConnect to connect to the cloud ServiceNet, which allows for a private connection to Cloud Files.
Yes. RackConnect connects your Rackspace cloud as an additional interface on your firewall; therefore, it allows you to connect to a firewall that has multiple segments set up if enough ports are available. Our data center can perform a visual inspection of the firewall to ensure that there is an available port to connect to RackConnect.
Customer-owned Active Directory domains can be extended over RackConnect. This includes Active Directory domain controllers in your dedicated environment or in your cloud environment.
If you are planning to deploy domain controllers in the cloud, and you promote a cloud server to a domain controller, be sure to create a ticket and inform the RackConnect team about this change. You must manually create a rackconnect user account on the Domain and add this account to the Domain Admins global group. We will add the DOMAIN\rackconnect account to the RackConnect system instead of rackconnect to get RackConnect to work with your domain controller cloud servers.
Additionally, Active Directory requires a large number of open ports to function properly, so we recommended that you create RackConnect network policies that allow full access between your cloud and dedicated environments.
Important: RackConnect network policies are limited to port ranges of 100. For details, see Managing RackConnect network policies.
Note: Connecting cloud servers to the Intensive Active Directory domains is not currently supported.
The Rackspace cloud does not allow for additional IP addresses on the private interface. The best workaround for hosting multiple SSL sites would be to host each site on a separate cloud server, or use PAT (Port Address Translation).
For more details about PAT, see Multiple SSL certificates on a single RackConnect cloud server (PAT).
Using Cloud Load Balancers can be a great solution. The key is to clearly understand the use cases for this configuration. Load Balancers works best when all servers to be load balanced reside in the cloud. If dedicated servers need to be load balanced, or cloud and dedicated servers are to be load balanced together, you should deploy RackConnect with an F5 load balancer. The firewall used with RackConnect further isolates and protects the customers dedicated servers.
Also note that when you use Load Balancers with RackConnect, all Internet traffic comes and goes through the cloud, and you pay for all outbound bandwidth at the standard Load Balancers rate. This bandwidth is not included in the “included” bandwidth that comes with each dedicated server.
For more details, see Use Cloud Load Balancers with RackConnect.
Snapshots taken of a server before the cloud account was set up with RackConnect should not pose a significant problem after the account is set up with RackConnect. However, a problem can occur if the network stack has been modified or iptables have been set to block all access (which will block the RackConnect system from connecting). Specifically, the snapshot must have a clean SSH configuration that permits root login, with port 22 open in iptables, and accepts password authentication.
You can view the public IP address of your RackConnect cloud server in the following places:
In the RackConnect Management Interface of the MyRackspace Portal, view the IP address on the Overview tab for the server.
You can retrieve the public IP address through the Cloud Servers API by querying for server details. The field containing the RackConnect Public IP address is called
accessIPv4. For details about using the API to retrieve server information, see the Getting server details section in the Cloud Servers v2 Developer Guide.
It is not currently possible to use cloud server images (snapshots) created in one region to spin up cloud servers in a different region. We expect this functionality to be available in late 2013.
Due to the limitation above, if you would like to use cloud server images with RackConnect, follow this process:
- Create a cloud server in the same region as your RackConnect configuration.
- After the cloud server is deployed and configured as you would like, you can create an image (snapshot) of it.
- You can now create new cloud servers from this image, as long as they are created in the same region in which your RackConnect configuration is located.
Note: If you have existing cloud server images that were created in a different region than where your RackConnect configuration is located, then it will not be possible to use them with RackConnect until the first half of 2014 (expected time frame).
Yes. By default the cloud servers are directly exposed to the Internet and only the internal OS firewall is available for protection. You can deploy RackConnect as a front-end dedicated firewall to provide a single entry point for public traffic to all your cloud servers. In addition, it allows a single point to consolidate your firewall rules for all cloud servers through the use of RackConnect network policies.
