8Appendix — Hardware Cabling BestPracticesHandling Static Sensitive ComponentsStatic electricity can damage memory modules, system boards, and other static-sensitive components.To prevent damaging the system, follow these precautions:• Move and store all components in the static-protective packaging.• Place components on a grounded surface before removing them from their static-protectivepackaging.• Grounded surfaces include static-dissipating mats or grounded workstations.• Always be properly grounded when touching a static-sensitive component. To properly groundyourself, wear a wrist strap or boot strap made for this purpose.• Handle the component by its edges. Do not touch solder joints, pins, or printed circuitry.• Use conductive field service tools.Host Cabling For Remote ReplicationThe Remote Replication premium feature provides online, real-time replication of data between storagearrays over a remote distance. In the event of a disaster or a catastrophic failure at one storage array, asecond storage array can be promoted to take over responsibility for computing services. The RemoteReplication premium feature requires a dedicated host port for replicating data between storage arrays.After the Remote Replication premium feature has been activated, one host I/O port on each RAIDcontroller module is solely dedicated to replicating operations.NOTE: If Remote Replication is activated, host port 3 on each RAID controller module is dedicatedfor the communication that occurs between the two storage arrays (primary and secondary virtualdisks). If the Remote Replication premium feature is not being used, these host ports are availablefor ordinary host connections.Cabling For PerformanceData transfer performance is enhanced by maximizing bandwidth, which is the ability to process moreI/O across more channels. Therefore, a configuration that maximizes the number of host channels andthe number of drive channels available to process I/O, maximizes performance. Faster processing speedsalso maximize performance.In addition to planning a topology that provides maximum performance, choose a RAID level that suitsthe planned applications.35 |
