Going faster by not moving – IBM Appliance M2001

totoise-rocket-patch

Go faster. Faster. Move it! Or actually don’t move it. There are times when to go faster you need to stop moving. We are all familiar with the parable of the tortoise and the hare – where slow and steady wins the race. But what about not moving at all? Sometimes that makes you go much faster. And in the case of the latest update to the IBM MQ Appliance that is exactly what we are doing. Hopefully you already know about the MQ Appliance, which IBM releases early in 2015, and have continued to enhance since its release. You can read my original entry here, and the update at the end of last year here.

 

But today, April 19th, IBM is announcing another update to the MQ Appliance which not only provides additional functional enhancement, by allowing queue managers to both synchronously replicate for HA and also asynchronously replicate for DR, and adds support for the AMQP based MQ Light API, but also sees a small but important hardware update, making this a slightly refreshed model – the MQ Appliance M2001.

HA+DR

There are 2 key hardware changes in this model update. To help support the simultaneous HA and DR function, which would use both existing 10Gb network cards, the existing 2 port connection is being replaced with a 4 port connection, providing 4 of these 10GB network ports, enabling 2 to be used for HA and DR and ensuring 2 can be used by applications connecting to the appliance, as well as the existing 1Gb ports.

M2001

The second hardware change is the replacement of the existing pair of 1.2TB hard disk drives (HDD) with a pair of 3.2TB solid state drives (SSD). As well as the benefit of the greatly increased storage capacity, the major benefit of using SSDs is the increase in performance for persistent message throughput. The MQ Appliance is a highly capable system which can process a lot of MQ messages. However, when using persistent messaging, which needs to be written to disk, it is critical that the storage can keep pace with the high rate of workload being handled by the system and at times with heavy workloads the spinning disk simply couldn’t move fast enough. IBM has selected the latest generation of SSDs to provide large capacity, high performance for both reading and writing data at high rates, and also this latest generation of SSDs, even if the MQ Appliance is used heavily all day, every day, should last for the 5 year supported lifespan of the MQ Appliance. Therefore, this provides the payoff from our ‘tortoise and hare’ parable – with no moving parts in the SSDs, they can be a lot faster than spinning disks. Expect to see updated performance figures for the new MQ Appliance M2001 around the time of its availability (June 10th 2016), but early figures suggest for some workloads performance improvements of up to 3 times have been seen.

 

There continue to be 2 editions of the MQ Appliance – the M2001A, providing full access to all the processor cores, and the M2001B, which provides access only to a subset of the cores – with an upgrade available from the B to the A system if needed. For customers who may have already purchased the MQ Appliance M2000, please talk to your IBM sales rep to see whether your appliance can take advantage of an upgrade of the HDDs and network card if available.

 

With the improved HA and DR functions, the increased storage capacity and the greatly increased performance, IBM believes this enhanced MQ Appliance makes even more sense to be used as the heart of your IBM MQ deployment, or as a highly available pair of appliances that can be deployed anywhere you need MQ capability. And for customers who may be running older versions of MQ which were recently subject to an announcement of End of Support – as can be seen here – then the latest version of the IBM MQ Appliance can represent a very good deployment option which is then far simpler to deploy as well as to maintain.

 

By moving from spinning disks, to SSDs with no moving parts, you really can go faster by standing still.
