Configuration details
Storage area network (SAN) configurations that contain Storwize® V3700 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 V3700 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 V3700 clustered systems. - External storage system configuration details (iSCSI)
Plan for your external storage system configurations through iSCSI connections with Storwize V3700 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 V3700 configuration details to Fibre Channel host bus adapters (HBAs). - Fibre Channel 10-gigabit Ethernet fabric configuration details
Storwize V3700 supports 10-Gigabit Ethernet (10 GbE) Fibre Channel over Ethernet (FCoE) fabric configuration. If any of the configuration rules are invalidated because a component in the fabric failed, the configuration is still supported until the failure can be corrected and configuration is returned to normal operation - Converged network adapters on host systems
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 V3700 nodes to ensure that you have a valid configuration. - SAS configuration details
Apply these Storwize V3700 configuration details for serial-attached SCSI (SAS) host connections. - Fibre Channel and FCoE SAN configuration details
Apply the following Storwize V3700 configuration details for Fibre Channel and Fibre Channel Over Ethernet (FC/FCoE Gateway, FCF) 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. - 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.
