Unique Dell EqualLogic Peer Storage Architecture
The Dell EqualLogic PS4100 and PS6100 are replacing the PS4000 and PS6000, respectively, as the new EqualLogic flagship offerings. With a new, faster backplane that can handle more drives, the new architectures are a perfect balance of performance and capacity.
For legacy Equallogic customers, the backward compatibility of the 6100 and 4100 series arrays with all previous models continues to disrupt the traditional frame-based vendors.
The PS4100 and PS6100 come with the same enterprise SAN features built directly into the firmware; the only difference is a revved up controller on the PS6100 and a higher number of supported attributes. We thought a side-by-side comparison might help those that are familiar with the PS Series.
|Cache||4GB Per Controller||4GB Per Controller|
|Backplane Speed||6G SAS||6G SAS|
|GbE Connections||2 Per Controller||4 Per Controller|
|Members Per Group||2||16|
|Snapshots Per Volume||512||512|
Here’s an interesting point. Although you cannot have more than 2 PS4100s in a Group, if you add a single PS6000/PS6100 to the group the limits disappear and there are no restrictions. Site to site replication implies 2 groups.
