The Dell EqualLogic PS4000x appliance provides a performance/capacity mix which makes it ideal as a host for a small to medium sized virtual environment, or perhaps as a high performance tier to a backup staging area or archive store.
The recent introduction of 450GB and 600GB 10K SAS disks make this iSCSI SAN array ideal as a high capacity target for a replicated production environment based upon another PS4000, PS5000 or PS6000 series unit. It is entirely possible to replicate from a PS6000 series array to a PS4000 series appliance, which means that disaster recovery in now within reach of even the tightest budget.
The PS4000X utilises 10K serial attached SCSI (SAS) disk, which offers an excellent combination of performance and capacity. The 10K SAS based PS4000X offers approximately double the IOPS performance of the SATA based PS4000e, so it could be utilised to host a virtual environment with some high transactional workloads.
As with all EqualLogic arrays, storage is virtualised across all drives within the array to deliver maximum IOPs performance. Volumes are assigned from this virtual 'pool' of storage and delivered to connected servers using a free iSCSI initiator such as that provided by Microsoft. The PS4000X can be configured at RAID 10, 50, 5 and 6 (Aka RAID DP).
The cost of the PS4000x includes all functionality including replication, snapshots and thin-provisioning. EqualLogic's innovative design means that implementation of each inclusive feature is more comprehensive and detailed that competing solutions at the same or higher prices.

* Following the introduction of the 450GB 10K SAS drive it is anticipated that the 400GB drive option will be retired relatively soon.
