EqualLogic PS Series - The Best iSCSI SAN?

image

The Dell EqualLogic PS Series is the industry’s leading iSCSI based enterprise SAN solution that offers an affordable alternative to traditional fibre channel storage systems. The PS Series virtual storage architecture enables exceptional performance, simple set up, automated management, multiple tiers of storage, on-demand scalability, and seamless interoperability with virtual infrastructure solutions.

EqualLogic PS6100 Series - The Best iSCSI SAN Just Got Better!

image

Dell EqualLogic PS6100 series arrays deliver exceptional flexibility across multiple configurations. Fluid Data technology seemlessly tiers data between SSD, SAS and NL SAS disk to reduce latency and maximise performance. The 24-drive chassis delivers up to 72TB from a single 4U appliance.

EqualLogic PS6500E - Best Value iSCSI SAN

image

The Dell EqualLogic PS6500 is a high-density virtualized storage array that can deliver a hugely scalable iSCSI SAN. The PS6500E or 'SUMO' appliance accomodates 48 SAS / SATA drives into just 4U of rack space, up to 16 appliances can be combined into a storage pool delivering a massive 1.5PB of high performance space.

PS4100 Series Entry Level Arrays, Enterprise Class Features

Dell EqualLogic PS4100 series arrays provide datacenter class storage to small to medium sized businesses. Based upon the best selling PS6100 series arrays, the all inclusive licensing model ensures that there are no hidden costs - everything is included 'out of the box' to create a high performance, robust storage environment with a simple route to disaster recovery.

Virtualisation with VMware and EqualLogic

By combining VMware Infrastructure and Dell EqualLogic PS Series arrays customers are provided a solution that delivers improved infrastructure scalability and management, high availability, significant cost savings and comprehensive disaster recovery. The excellent relationship between EqualLogic and VMware means that PS Series arrays are always amongst the first to support new features and standards.

Are You Ready for the Bake Off?

We'd be lying if we told you that Dell EqualLogic was the only iSCSI SAN platform out there, but we're entirely comfortable telling you that it's the one you should choose. When you're ready for the 'bake-off' we'd love to show you why WE sell more EqualLogic arrays than all the other vendors arrays put together...

EqualLogic 10GbE - Here, Now and Faster than Fibre

image

For a long time Fibre Channel storage vendors boasted about higher bandwidth connectivity into their arrays. Old school fibre channel buyers thought that Gigabit Ethernet iSCSI might compromise storage performance. We knew that wasn't the case, but if you're looking for high bandwidth it doesn't get fatter than this! Four 10GbE connections per array = blazing fast iSCSI!

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.
