February 3, 2003 EMC CLARiiON Open Systems Configuration Guide Some examples of valid server connections to a CX400 or FC4700 with MirrorView are • Highly-available dual-HBA configuration with minimum load-balancing - 63 servers, each with 2 HBA ports - Each HBA port cabled and zoned to allow it a path to only one port on one SP - MirrorView connections from the CX400 or FC4700 to one other storage system (126 HBA ports x 1 path = 126 initiators. These 126 initiators + 2 MirrorView initiators = 128 initiators, the maximum number per CX400 or FC4700). Note that each server has one path to each SP for a total of two paths per server to the storage system. • Highly-available dual-HBA configuration with maximum load-balancing - 15 servers each with 2 HBA ports - Each HBA port cabled and zoned to allow it a path to both ports on each SP - MirrorView connections from the CX400 or FC4700 to four other storage systems - Each server must support four paths to an SP (30 HBA ports x 4 paths = 120 initiators. These 120 initiators + 8 MirrorView initiators = 128 initiators, the maximum number per CX400 or FC4700.) Note that each server has eight paths to the storage system. Sample CX200 configurations • Highly-available dual-HBA configuration with no load-balancing - 15 servers, each with 2 HBA ports - Each HBA port cabled and zoned to allow it a path to only one port on one SP (30 HBA ports x 1 path = 30 initiators, the maximum number per CX200) - Each server runs PowerPath Base to provide HBA failover, but no load balancing. Note that if the server has more than 2 HBA ports, you can have load-balancing between the server and the fabric, but not between the server and the storage system because a CX200 can have only one port per SP connected to a fabric. Access Logix Models AL200-Tx for CX200, AL400-Tx for CX400, AL600-Tx for CX600, ACLG47-Tx for the FC4700, ACLG45-Tx for the FC4500, ACLG53-Tx or AL53Ty-Tx for FC53001, where x is the storage tier and y is either 1 or 5. For FC4500 SAN configuration, ACLG45-Tx must be v6.32.01 or higher with PROM v2.08 or higher. Direct Attached Storage (DAS) Configuration Rules Storage System without Access Logix Storage Systems - Any If more than one server is directly attached to a storage system, all servers attached to the storage system must be in the same cluster. Storage System with Access Logix Storage Systems - CX400, CX600, and FC4700. AL400-Tx for CX400, AL600-Tx for CX600, and ACLG47-Tx for the FC4700, where x is the storage tier. Number of Servers CX600 - 8 servers maximum CX400 or FC4700 - 4 servers maximum Note: Direct attach is not supported for a CX200, FC4500, or FC5300 with Access Logix. Hub Attached Configuration Rules Number of Servers and Storage Systems Servers - 1 to 2, running the same operating system. Storage Systems - 1 to 4 FC4500, FC5300, FC5500, and FC5700.
