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!

EqualLogic - an ideal storage platform for VMware vSphere PDF Print E-mail

 

vmware VSphere Vstorage ESX EqualLogicEqualLogic iSCSI SAN will help you to get the best value from your VMware vSphere virtual infrastructure, leveraging the new VStorage API's to enable even tighter integration between the virtual datacenter OS and the storage platform.

This essentially means that VMware VSphere is able to offload some storage related tasks from the host operating system, taking advantage of functionality provided by the EqualLogic SAN, reducing server load and increasing performance.

Snapshot - Clone - Provision

VMware and EqualLogic have each offerred their own snapshot functionality for some time. VMware snapshots could be resource intensive and were storage autonomous with associated limitations, EqualLogic snapshots offered advanced functionality such as application consistency and space optimisation, but they operated independently from the virtualisation platform leading to increased complexity and administrative overhead.

The release of VMware vSphere sees the introduction of new VStorage API's which enable VMware to communicate directly with a VM aware storage platform. EqualLogic iSCSI SAN is one of the first virtual storage platforms to offer support for VStorage.

When vSphere is integrated with EqualLogic SAN operations such as snapshotting, cloning and provisioning new machines through VCenter will lead to the storage workload of such operations being passed directly to the SAN to complete. This in turn will reduce load on the ESX servers and reduce the time taken to complete many operations by between 50 and 75%.

Thin Provisioning

Thin provisioning of volumes has been offered by EqualLogic for some time, allowing IT departments to optimise utilisation of space in the storage pool, leading to the best possible return on investment.

Thin provisioning allows you to deliver full size volumes to your server OS, whilst only allocating the amount of space actually utilised on the array. For example: a thin provisioned 100GB volume will appear as a normal 100GB volume to Windows Server, but if only 10GB of the space is filled with data, it will only take up around 10GB on the SAN.

Previously ESX was not aware whether a volume was thin or fully provisioned and this could lead to inefficient space management as resources were relocated using tools such as Vmotion. vStorage API's allow ESX to work in conjunction with VM aware storage to help administrators realise the full benefit of thin provisioning without leaving VCenter.

 

There are many other areas in which VStorage integration allows you to get better value from your environment, so the question is - Why would you consider a platform that is not VM aware?
