Selecting server based on application requirements
Posted on 2012-08-15
We are due to onboard a new application soon for testing, it has 3 components - Component1, Component 2 and Component 3 that need to be on different servers. We have been working with the vendor and they suggest:
Component 1: Low Disk I/O, low CPU usage, needs about 16GB RAM. Can be virtualised
Component 2: Medium Disk I/O, low CPU usage, needs about 16 GB RAM.
Component 3: High Disk I/O, high amount of storage needed, medium CPU usage.
(I appreciate this is quite vague for the moment, but we are in very early stages).
I was curious - how do people decide what sort of server they need? We are an HP shop really, so would like to standardise on that, but how do you decide whether to go for:
i. Full server v blade
ii. If a full server, there are so many different types (DL, ML etc)
iii. Which model of the above
Or should the vendor be telling us this sort of thing? And how about deciding on RAID etc?
