Re: Raid 5 Disk Partition

it looks fine

but If you created a logical dive and want to create D: E: and so you need a third party software to do it

like

you can use a tool, such as Acronis disk director suite.

Re: Raid 5 Disk Partition

I would not setup my server this way.

Ideally you would setup 1 mirrored set for just the OS (C:\) and then for a file server setup a 2nd array, say 3 drives in a RAID5, for a data partition. Then if you ever need to you can easily expand the 2nd partition.

However, if you are budget limited I would create no more than 2 partitions on this server as is. 1 for the OS and 1 for a data partition. You gain nothing by splitting it up into 3 partitions and you limit yourself later if E:\ (as configured) runs out of space.

Re: Raid 5 Disk Partition

yes that is an ideal enviroment but involves 6 HDDs

but trbal yeah the configuration is properly set up(which you did)

Re: Raid 5 Disk Partition

Thx both

As to your suggestion my deployment is very simple with just 25 clients. i run os on c SQL on D and e is just a redirection folder for clients. My old ML 350 runs 3 HHD raid 5 3 partitions and has been doing so for last 4 years so i dont see any expansion in the near future. Apart from this is there any other issue in my config.

Re: Raid 5 Disk Partition

karl where do you get 6 drives from?

2 for a mirror pair (OS)
3 for a raid 5 data partition
5 in total.

Unless you want an online spare than yes, you will need 6 drives.


trbal, your config (3 partitions on 1 RAID 5) will work yes.

I would personally never do that, but it will work. Personally I would much rather have 1 big C:\ drive (RAID 5) then split it up by OS partitioning, but that is just me.

If you insist on multiple partitions I would limit it to 2 and use folders w/ntfs permissions to separate SQL from user data.

Again though all the above will work for what you are doing.
