The supported storage systems require a dual controller configuration. If you use the system in a HUB environment, you must set a unique loop ID for every connected host and storage system. For details about the microprogram versions for using HDLM, see the HDLM Release Notes. For details about storage system settings required for using HDLM, see the maintenance documentation for storage systems. Memory and Disk Capacity Requirements This section describes memory and disk capacity requirements. Memory Requirements A host requires 10 MB of memory. A remote management client requires 20 MB of memory. Disk Requirements The disk space requirements for hosts and remote management clients are as follows: • Host 600KB • Remote management client 3MB + p MB# # This size depends on the integrated trace files settings. The maximum size is 1000MB. When t is the integrated trace file size (the default value is 1000) and n is the number of trace files (the default value is 4), this value (p) can be calculated as follows: p = (t x n) / 1024 MB (rounded-up to the nearest integer) Number of Paths Supported in HDLM Table 3-2 Number of LUs and Paths Supported in HDLM on page 3-3 lists the number of LUs, the number of paths for an individual LU, and the total number of paths supported in HDLM.
