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 EqualLogic PS6100X iSCSI SAN appliance is based upon a new chassis design which can accommodate up to twenty four 2.5" 10K SAS disks. 300GB, 600GB and 900GB drive options can be utilised to deliver up to 21.6TB of fast (RAW) capacity. High performance disks, together with the high spindle count means that IOPs performance significantly exceeds that delivered by the capacity optimised PS6100E. This means the the PS6100X is suitable for use with demanding databases and virtual environments containing a large number of workloads. Careful sizing and planning is of course important, and is more straightforward with PS6100 series appliances (in comparison with the PS4000/PS4100 series) with support for more iSCSI connections, more volumes, more replicas etc.

Performance and Capacity Optimisation

The appliance can be purchased full or half populated. Storage is virtualised across all drives in the array (with the exception of those allocated as hot spares), so the more disks you have, the better the performance. The decision on which RAID level to be applied across the pool should be based upon the performance/capacity mix required for your workloads. RAID 10 offers maximum performance and can withstand multiple drive failures, yet it delivers the least space. RAID 50 offers a capacity increase with relatively little sacrifice in throughput and has proved to be the most common choice amongst our users. Use of RAID 6 and RAID 5 is less common due to concerns in relation to speed and resilience respectively.

Tiered Storage Architecture

The PS6100X can be deployed as part of a 'storage pool' in conjunction with any current or previous generation EqualLogic array. Whilst all disks within each appliance must be of the same size/type, there is no need to match disk technologies or capacities within a storage pool - indeed the EqualLogic architecture is designed to deliver tiered pools of storage with fully automated migration of data between tiers. The PS6100X is undoubtedly a very positive step forward, based upon an already-successful product range. This high capacity, high performance iSCSI storage option is sure to be well received by new and existing users alike.
