Recently purchased a new IBM server x3650 am I am unsure the best way to setup the RAID. I want to do RAID 5 but I have read that the OS cannot/shouldn't be put on the same array.

Thats what i was thinking

2 for  OS      RAID 1
4 for  DATA  RAID 5

I will probably purchase another spare to have sitting around.

You can go with all of them on one RAID since you have all disk the same size. The system won't have any trouble being on RAID 5. The usual way to do it is to have two 78 GB drives mirriored for the OS then the rest for data as a RAID 5.

If you go with the two drives as a mirrior you are going to most likely lose space make sure you parition correctly.

Thought that crossed my mind.

If a drive fails in the RAID 5 I need to swap it out.
If the OS is on the RAID 5 when it fails will it be able to rebuild the drive that it is running...?

Yes, I have setup Servers this way many of times because of how the customer purchased the hardware. I even had to set it up with two RAID 5 with 3 disks in each RAID to get the best performance for SQL.

Depending on where you are in relation to where the server is, ie. the datacenter is on the far side of town or you are away for the weekend, a hotspare is nice to have as it doesn't require you to drive in to swap the failed drive until you actually need to come into work.  Of course, the chances of another drive failing in the array after the first one has failed are astronomically slim, having a hotspare is good for peace of mind.  If the server is in your bedroom, forget about it.

The server is in our main office which I am at every weekday, 10 minutes from my house. so I would rather have the extra storage on the server and have a spare to swap in.

I will attempt 1 large RAID 5 across all 6 disks

Are you going to have two paritions or or 3? If you are going to have a system c:, d:, e: you would be best served having two RAID 5 for the I/O responses.

I will setup as 1 large RAID

It will appear as 5x146GB total size

Windows will be installed and I will setup network shares off of the c drive

EG

c:   Local disk c:

d:   Data        c:\Data
f:   Software   c:\Software
s:   Scanned   c:\Scanned




OR


2 disks RAID 1 for windows installation
4 disks RAID 5 for data

If you have a split back plane then you can setup C: and your Software & Scanned on D: on the same RAID 5. Then for your data on the second RAID 5 as one partition which will give you better access times on your HDs. If you don't want to do this then setup one RAID 5.

Don't have any data like shares on the C:. Have the shares and any other data on different paritions you don't want any data on the C: because this parition usually is the one that gets corrupted and if you need to reinstall you don't have to worry about moving any data off.

I've never setup a RAID from scratch b4.

When I get this server what are my steps.


Like how do I setup RAID 5

I will have the server and the Windows Server 2008. I'm assuming I setup the RAID (I don't know how) then I installed Windows Server 2008 creating 2 partitions c: for windows and d: for all of the shares.

Correct you configure the RAID containers first. When you get the server you will boot the server and you will see the commands to get into the RAID config from there you will have options to create the containers. If you haven't gotten the server yet then you can get the manufacture to create the RAID config for you.

hi,
please submit for SystemX 3650, the Type-Model, and tell us if you have purchased/ordered some
add on (Raid). Until we don't know if your 3650 hs a

http://www-947.ibm.com/systems/support/supportsite.wss/selectproduct?familyind=5310494&brandind=5000008&oldbrand=5000008&oldfamily=0&oldtype=0&taskind=2&matrix=Y&psid=bm

and very useful
http://www.redbooks.ibm.com/abstracts/tips0054.html

Example: if you have a 8k-l, you are not able to make a Raid5, by 8k yes.

However, download the last iso image (probably it 'll come with 3630 box) of ServeRAID 9.x Support CD,

http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=SERV-RAID&brandind=5000008

and, boot from it, before do any OS setup. Build Arrays compatible with number of HDs and Controller type (on this miniOS/program, you can also be sure about type of card).

You can also press Ctrl-A (I am not sure) during BIOS phase and run mini raid setup program.
(by CD you can also update fw, at last level).

About partitions, you can do anything: build 2 array R1 and R5, or just a R5 and partition logical disk at RAID level. Or make a full logical drive and build partition during OS setup.
The best is have 2 hd in rad1 for os, and 3+ hds in R5 for  data, but it depends from what you have to do by server.

With your server, will come also a ServerGuide CD. IBM and many people use this to configure server,
install OS, retrieve drivers. I prefere don't use it. If it goes ! is faster, it's like a satellite navigator:
it leads fastly to the target, but you have not the minimal idea how, where, .. you have arrived!
See you!

hi,
that's all right !
The disks are on a backplane, and an internal Card (8k-l) manages disks. This card is not on a normal
PCI slot (those you see on the rear of server), but it is on a special slot inside.
You'll open the server, remove this (hold it, even if seems nothing) and insert the 8k you bought separately.
I have not well understood if you have bought the 8k, however continue with indications on the previous post.

I did not purchase it but will need it for RAID 5 so I just purchased one for $296

With this card I will be able to do RAID 1 and RAID 5

I am also setting up my x3650. If you purchased the HDD all together, I would actually suggest RAID6 instead of 5 to protect against 2 HDD failing at the same time.
I have 4 x 146GB, setting it up for RAID 6 via the ServeRaid 8K

Few notes:

The x3650 7979 model comes with the serve raid 8k card already installed.

I installed -
  raid 1 for the OS 2-146GB SAS 15K
  raid 10 for data 4-300GB SAS 15K

Speeds are amazing

Currently running windows server 2008 x64 but need to downgrade to server 2003 because of some program incompatibility.
