It was only a couple of months ago when the Dell EqualLogic PS6000 replaced the PS5000 as the new EqualLogic flagship. We were excited to see Dell moving upstream with a faster controller and more connection speed, but we felt something was missing. Many potential customers wanted to get on board the EqualLogic train but could not afford it.
Dell just announced the release of the PS4000 which fits nicely in the Small-Medium sized business niche. Remaining true to EqualLogic’s tradition of waiting until a product was ready before announcing it, the PS4000 hit the ground running. Quite honestly, we got more than we could have hoped for.
The PS4000 comes with the same enterprise SAN features built directly into the firmware; the only difference is a revved up controller on the PS6000 and a higher number of supported attributes. I thought a side-by-side comparison might help those that are familiar with the PS Series (either the original PS100 et al or the PS5000).
|GbE Connections||2 Per Controller||4 Per Controller|
|Members Per Group||2||12|
|Snapshots Per Volume||128||512|
|Volumes For Replication||32||192|
|Replicas Per Volume||128||512|
Here’s an interesting point. Although you cannot have more than 2 PS4000s in a Group, if you add a single PS6000 to the group the limits disappear and there are no restrictions. Site to site replication implies 2 groups.
