Dear all,

We are expecting a new disk array to arrive in a few weeks to add to our VMWare cluster along with additional RAM. We will be adding 6TB of additional fast storage to the cluster based usingĀ an Equallogic PS4100X SAN with will pair with our existing PS6500E unit.

We will also be doubling the host RAM on each server to 192GB. This will ensure our cluster remains state of the art for our needs over the coming years and that we can allocate more memory to virtual servers.

In order at add the disk array and RAM, I will need to take each of the 4 VMWare servers down a number of times. This will have little impact on service, except to possibly cause some slight slowdown in the running virtual servers as they will be temporarily squeezed onto 3 servers instead of spread out over 4.

The plan is to add the RAM first which will make further operations have less impact on performance.

Dates

25th June, Noon – 2pm : vmhost-11 having a RAM upgrade. This is the first of 4, so will cause some strain to the systems as vmhost-11 is taken out of service for 2 hours. After this one is done, there will be less impact.

UPDATE 16:12 25th June: vmhost-11 is now running with 192GB RAM…

Next upgrade: 23rd July: vmhost-12 will have its RAM upgraded.

UPDATE 23rd July: vmhost-12 is now running with 192GB RAM..

Next upgrade: 28th July: vmhost-13 AND vmhost-14 will have their RAM upgraded.
