The document provides an overview of storage connectivity and performance considerations for the DMX-4 architecture. It notes that HBA speeds range from 60MB/sec to 150MB/sec, switch ports support 4GB/sec, FA processors support up to 12,000 IOPS with approximately 6,000 IOPS recommended per FA 4GB fibre port. Disk adapters support up to 5,000 IOPS and the cache can process up to 6,000 IOPS before requiring write limits.
