If you want to use SyncRep both Pools should  be "identical" in terms of iops/latency. Otherwise the slowest pool will limit your performence. Depending on your workload 2x1GbE should be enough. Keep in mind that most ppl use the last ports for a dedicated management so your PS6000 gives only 3 usable ports. The PS4100 comes with NEARLINE SAS which are slighlty faster than the old SATA disks. If you have SANhq available take a look to the volume which you wanna Syncrep'ed. Regards, Joerg
Hi Quick question as per your experiences. We have a couple of EQL's in different groups and I want to move one member to another group in order to configure SyncRep on it. I can choose between a PS6000 with 7.2k SATA disks or a PS4100 with 7.2k SAS disks. I was thinking of taking the PS4100 since it has SAS disks eve´n though they have the same RPM I figure SAS is faster, not really sure about this. On the other hand the PS6000 have four ethernet ports instead only two ports on the PS4100, I guess I can get more MPIO paths using the PS6000 enhancing performance. As you can tell I'm not sure which one to use. Any insight would help thanks.
PS6000 or PS4100
