EqualLogic PS Series - The Best iSCSI SAN?

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!

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

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

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 PS4100 PS6100 get 10GbE

Dell has added 10GbE connectivity to their latest EqualLogic PS6100 Series and PS4100 Series arrays.

It's no suprise for the PS 6100 series, however it is the first time the PS 4100 users have been able to take advantage of high-bandwidth 10 Gigabit Ethernet into the entry-level storage platform. Entry-level does not really do the PS4100 series justice because this change actually extends the reach of the lower cost arrays even further, most notably in a supporting role to a 10GbE based PS6010/PS6110 series solution. As we have discussed extensively on this site, adding PS4000 series arrays to a new or existing storage pool containing a PS6000 series unit negates any feature lockdowns which are present when the arrays are deployed in a PS4000-only configuration. Historically users may have been reluctant to add PS4000/PS4100 series units in this way because of (questionable) concerns about bandwidth, however this is no longer a consideration.

The 10GbE storage arrays are designated PS4110 and PS6110 respectively, this is reflected in model numbers so PS4110X is the 10K SAS derivative, PS4110XV 15K SAS etc. Similarly PS6110X is the 10K SAS PS 6100 series array, PS6110XV 15K SAS and so on.

Dell EqualLogic PS6100 Series

Dell continue development of the successful EqualLogic iSCSI SAN platform with the release of the PS6100 series - delivering increased performance, higher capacity and greater flexibility through the application of Dells innovative 'fluid data' technology.

The PS6100 series arrays, as were the PS6000 series appliances before them, are designed to meet the performance and availability demands of virtual environments in medium to large organisations. Flexible configurations, combined with the well documented EqualLogic scale-out architecture and fully inclusive licensing model has enabled Dell to become, and remain the established market leader in iSCSI storage.

Key changes to the range with the introduction of the PS6100 series include:

Choice of either 2.5" or 3.5" drives in a 2U or 4U form factor
PS6100E - 24 X 3.5" 500GB / 1TB / 2TB / 3TB 7.2K NL SAS Drives, delivering up to 72TB in a single appliance
PS6100X - 24 X 2.5" 300GB / 600GB / 900GB 10K SAS Drives, delivering up to 21.6TB of performance storage
PS6100XV - 24 X 2.5" 146GB / 300GB 15K SAS Drives, delivering up to 7.2TB of high-performance storage
PS6100XV 3.5 - 24 X 3.5" 600GB 15K SAS Drives, delivering up to 14.4TB of high-performance storage
PS6100S - 24 X 2.5" 200GB / 400GB SSD Drives, delivering up to 9.6TB of low-latency, high-performance storage
PS6100XS - hybrid array featuring a mix of SSD and 10K SAS for optimal responsiveness across tiered workloads

Dell EqualLogic PS4100 Series

The Dell EqualLogic PS4100 series builds upon the firm foundation established by the Dell PS4000 series since its introduction in 2009. Originally cast as an entry-level iSCSI SAN solution it was quickly apparent that the PS4000 appliances made enterprise features available to all for an entry-level price. The Dell EqualLogic PS4100 arrays are sure to enhance this reputation with increased performance, increased capacity and sleek new chassis designs accommodating 2.5" 10K and 15K SAS plus 3.5" SATA and 15K SAS drives. The comprehensive Dell EqualLogic feature set remains including application consistent snapshots, thin provisioning, replication, VMware vSphere and Hyper-V integration, detailed monitoring/reporting with SANHQ and more.

So what are the key differences between the PS4000 series and the PS4100 series?

PS4100E - 12-Drive Chassis. Choice of 500GB 1TB 2TB or 3TB 3.5" 7.2K NL SAS disks delivering up to 36TB

PS4100X - 24-Drive Chassis. Choice of 300GB 600GB or 900GB 2.5" 10K SAS disks delivering up to 21.6TB

PS4100XV - 24-Drive Chassis. Choice of 146GB 300GB or 600GB 2.5" 15K SAS disks delivering up to 14.4TB

PS4100XV 3.5" - New 12-Drive Chassis. Choice of 300GB or 600GB 3.5" 15K SAS disks delivering up to 7.2TB

EqualLogic + NAS = Unified Storage

Dell has announced the next stage in the evolution of the EqualLogic storage platform - the Dell EqualLogic FS7500.

The FS7500 is effectively a 'NAS Header' which can be combined with a new or existing EqualLogic storage stack to deliver both block and file capabilities in a single, flexible storage pool.

Protocol support includes CIFs, NFS, NDMP SNMP, iSCSI, Active Directory, LDAP and more. Each dual-controller FS7500 system can support up to eight EqualLogic PS Series arrays with a max system size of 510TB.

The system is managed through the familiar EqualLogic Group Manager and is one of the first to be powered by the Dell Scalable File System (DSFS)- which we will see extending further into their portfolio as part of their new 'Fluid Data' strategy.
