Anyone who is a fan of cheesy sci-fi movies, or soundtracks by Queen will have the words “Flash, Flash I love you but we only have 14 hours to save the earth” running through their head, along with the line in the song that goes “Flash aaaaah, saviour of the universe”. And of course he did save the universe from Ming the Merciless.
But what if I told you Flash could also save your business? Not Flash Gordon of course, but flash storage, in the form of the SSDs that are now a part of the IBM MQ Appliance M2001 which is now generally available (June 10th 2016). We did cover this in an earlier blogpost, but I thought I would take advantage of our initial shipment date to cover just how critical the IBM MQ Appliance, backed by state of the art 3.2TB SSDs can be to your business.
Each MQ Appliance M2001 model has 2 of the 3.2TB SSDs in a RAID 1 configuration. This means that every persistent message and all log data is written not just once to the SSD storage, but twice giving you complete redundancy of data. And a key part of the MQ Appliance functionality is the High Availability configuration – essentially nothing more than a simple menu option when creating a queue manager – allowing you to have the MQ queue manager on one MQ Appliance synchronously replicated to another MQ Appliance. This means that any message written to the SSDs on one MQ Appliance is not just copied to the second pair of SSDs but is written under the same unit of work that writes the messages on the first MQ Appliance. This therefore means you have 4 copies of the message stored for both reliability and availability.
Another part of the MQ Appliance update was the ability to do not just synchronous replication for High Availability but also asynchronous replication for Disaster Recovery to another MQ Appliance. Therefore you can point the MQ queue manager at another, typically off-site MQ Appliance and the same message will replicate there, ensuring there are another 2 copies of the message, and providing your business with a highly resilient messaging system designed to ensure optimum reliability and availability of messages.
After all, think about how important your messages are to your business. In effect, they are your business. Your messages are your business transactions, your new orders, your customer address details, your stock levels and distribution information. Lose your messages and you lose everything.
With the latest SSD technology inside the MQ Appliance you are calling on Flash to save your business – and with the MQ Appliance M2001, Flash saves the day again.
