Dell EqualLogic PS series Review
Dell Equallogic PS Storage System: a true virtualized iSCSI Storage Platform


Valuable Features:

a. A true virtualized storage system or enterprise storage system for capacity/data level virtualization. b. Performance increased with capacity if additional array included with existing deployment (Scale up architecture). c. Firmware compatibility across models and generations. Virtualization can be done with any generation and any feature model. d. All included application model. Need not to worry about application selection or pricing. Even if any new application/functionality included into PS Series platform in future that will also be entitled for current system.

Room for Improvement:

a. Only iSCSI interface. No choice for Fiber Channel connectivity. Have to select either 1G or 10G connecting iSCSI interfaces. b. Have to buy at pre-configured capacity models. Cannot buy 1 or 2 disks to increase existing capacity. c. Limitations to mix different types of disk (SSD, SATA, SAS) into same enclosure. d. Higher price at entry level systems compared to competition. For larger deployment price becomes more than competitive.

Other Advice:

a. Equallogic PS series arrays are the best suited storage platform for mid to high level enterprises. b. Cost of acquisition may seem to be higher but TCO is lower when compared for the high capacity deployments for virtualized environment. c. A very easy to use interfaces and easy to use wizard based configuration. d. PS Series comes with embedded 24x7 supports from Dell to ensure zero system downtime.
