New Server - Number of Disks - 3 or 5

[maxrebo]

Hi,

Im speccing up a new server and i was wondering how many disks i should go for?, 3 or 5?. This will be used as a VMware Host with multiple VM`s. The main one being a fileserver. So looking at a minimum of 2tb storage space

 

Thanks in advance

5 the rest of the word in this post are to get around the minimum word count.

5 - more words

If the question was three or five, and we are not allowed to write one word answers, then I say five too!

Against the Server of Caerbannog, first shalt thou take out the Holy Ordering Book, then shalt thou count to five, no more, no less. Five shall be the number thou shalt count, and the number of the counting shall be five. Three shalt thou not count, neither count thou four, excepting that thou then proceed to Five. Six is right out. Once the number five, being the fifth number, be reached, then lobbest thou thy Holy Ordering Book of Antioch towards thy bursar, who being naughty in My sight, shall snuff it.

Why would you not go for 6 disks?

Exactly what I was thinking but if it's a straight choice between 3 and 5 then 5

4, and RAID 10.

5 and raid 10 with a hot spare

Surely raid 6 with a hot spare.

Not for a VM Host machine. You have to go One Big Raid 10. Raid 6 is not good for write speed due to dual parity.

You don't *have* to at all. Its all about weighing up speed/disk(space) cost and fault tolerance. Raid 6 could be the best solution for the environment.

Yes sorry for using the phrase "Have", no does not need to go with OBR10. We need to know what Maxrebo means by "multiple VM's" a rough number would be good to know also what applications\services they will be handling.

Hi,

Thanks for your replies, i think there will probably be around 4 VM`s on, One used for Office 365 DIRSYNC, another as a file server and another 2 yet be be decided.

I think i will go for 5 disks.

 

Cheers
