Configuration details
Storage area network (SAN) configurations that contain Storwize® V5000 nodes must be configured correctly.
- Storage systems
- Nodes
- Fibre Channel host bus adapters
(HBAs)Note: If the system has an FC adapter fitted, some host systems can be directly attached without using a SAN switch. Check the support pages on the product website for the current details of supported host OS / driver / HBA types.
- Converged network adapters (CNAs)
- Fibre Channel switches
- iSCSI Ethernet ports
- SAS adapters
- Fabrics
- Zoning
- SAN configuration and zoning rules summary
Storwize V5000 systems during normal operations in a Fibre Channel environment are defined by supported configuration and zoning rules. If a single failure causes one or more of these rules to be invalidated, the configuration is still supported until the failure is corrected and the configuration is brought back into a normal supported mode. - External storage system configuration details (Fibre Channel)
Plan for your external storage system configurations through Fibre Channel connections with Storwize V5000 clustered systems. - External storage system configuration details (iSCSI)
Plan for your external storage system configurations through iSCSI connections with Storwize V5000 clustered systems. - Fibre Channel port masking
With Fibre Channel port masking, you control the use of Fibre Channel ports. You can control whether the ports are used to communicate to other nodes within the same local system, and if they are used to communicate to nodes in partnered systems. Fibre Channel port masking does not affect host or storage traffic. It gets applied only to node-to-node communications within a system and replication between systems. - Fibre Channel host bus adapter configuration details
Apply these Storwize V5000 configuration details to Fibre Channel host bus adapters (HBAs). - Converged network adapter configuration details
Apply these system configuration details to converged network adapters (CNAs). - iSCSI configuration details for host connections
You must follow these configuration details for iSCSI host connections. - Node configuration details
Apply these configuration details to Storwize V5000 nodes to ensure that you have a valid configuration. - SAS configuration details
Apply these Storwize V5000 configuration details for serial-attached SCSI (SAS) host connections. - Fibre Channel SAN configuration details
Apply the following Storwize V5000 configuration details for Fibre Channel switches to ensure that you have a valid configuration. - Example SAN configurations
Examples of typical ways to configure your system and an associated Fibre Channel network are provided to guide you in setting up your SAN configuration. - HyperSwap system configuration details
You can create an IBM® HyperSwap® topology system configuration where each control enclosure that is used to access a HyperSwap volume is physically on a different site. When used with active-active relationships to create HyperSwap volumes, these configurations can be used to maintain access to data on the system when power failures or site-wide outages occur. - Quorum disk
A quorum disk is an MDisk or a managed drive that contains a reserved area that is used exclusively for system management. - Bitmap space configuration for Copy Services, volume mirroring, or RAID
Copy Services features and RAID require that small amounts of volume cache be converted from cache memory into bitmap memory to allow the functions to operate. If you do not have enough bitmap space allocated when you try to use one of the functions, you will not be able to complete the configuration. - Comparison of mirroring methods
The information in the following table compares the various methods that you can use to mirror your volumes. - Zoning details
Ensure that you are familiar with these zoning details. These details explain zoning for external storage system zones and host zones. More details are included in the SAN configuration and zoning rules summary.
