ABSTRACT
This article explains whether a user will gain additional bandwidth on the storage area network (SAN) if two host bus adapters (HBA) were placed in servers instead of one. In theory, when adding a second storage adapter to a server that is attached to a separate switch and fabric, it should be possible to improve bandwidth. But it depends on how the storage is configured , what the application workload is and where the bottlenecks are. If neither the host adapter nor the logical unit numbers (LUN) are performance bottlenecks, users may not see a performance improvement. However, if the host adapter is a bottleneck and multiple LUN are being accessed, a performance improvement is possible. If a specific LUN is a bottleneck, try load-balancing across another LUN and, optionally, another HBA. Users may also want to consider what other traffic exists on the SAN and switches. Exercise caution when configuring a second adapter on the same peripheral component interconnect bus to avoid bus contention.
