The wraps are off the latest addition to the NetScaler SDX range with two new appliances the SDX 8400 and 8600 for the entry level markets.

Based on the MPX 8000 series hardware, the new SDX 8400 offers 4Gb of throughput which can be upgraded to the larger SDX 8600 for 6Gb of traffic management via licence key. Each 8000 series SDX features virtual architecture in a high performance hardware chassis which ships with entitlement to run 2 independent machines known as instances. Up to 3 more instances can be added to provide the maximum total of 5 supported by the hardware. Each instance can be tuned to suit the requirement with both functionality and capacity configured to ensure SLAs don’t slip at peak usage times.

Those familiar with the current SDX offering will note at this point that additional instances have historically been licensed in packs of 5 so there’s a new SDX instance 3 pack also available from today which can be deployed on any of the SDX range. And remember, upgrades for capacity and instance density only require a licence key rather than additional blades in a chassis as preferred by a number of other vendors so SDX offers a very flexible solution to a common problem.

So the obvious question is who’s going to buy one of these new appliances?

As these next generation NetScaler appliances mature, we’re finding the ability to host more functionality directly on the appliance allows further efficiency and service performance. These functionalities are moving beyond the traditional ADC feature set to not only provide support for enterprise/web apps but also mobile device and app management, cloud orchestration and support for like minded vendor technologies form the likes of Palo Alto, WebSense and one to watch, BlueCat Networks – who knows, we might even see a bit of Cisco technology running on a Citrix chassis one day. It’s where the ‘Next generation networks powered by Citrix NetScaler’ statement starts to become reality as more organisations move towards Software Defined Networks.

Should you buy one?

The typical IT industry response applies – it depends. If you need 2 instances then the new SDX 8400 appliances offer a very cost effective solution but if you are considering loading an SDX 8600 with a full 5 instances then take a very long hard look at the SDX 11500 before making a decision… more potential growth for not much more money.
