Designed for use in remote offices or small to medium businesses, the Dell EqualLogic PS4100 series of iSCSI SAN’s offers a disk drive capacity ranging from 12 to 24 drives of 2.5” or 3.5” NL-SAS or SAS drives. Additionally, PS4100 storage arrays offer highly virtualized peer storage, which enables linear performance and capacity. This means that these particular EqualLogic storage arrays are able to scale seamlessly alongside capacity, all the way up to 36TB in a single SAN solution, by means of innovative Fluid Data technology.
Dell EqualLogic PS4100 storage arrays feature up to a 60% IOPS performance improvement on a typical workload when compared to the IOPS performance of previous EqualLogic generations such as the PS4000. Other new high-performance features of the PS4100 iSCSI SAN includes dual controllers with 4GB cache per controller, a 6G SAS backplane and more, while the PS4000 only features a 2GB cache per controller and a 3G SAS backplane.
