ESX - vCenter / Backup | Raid configuration
Posted on 2009-02-24
We plan to build an esx environment like this;
2x DL 380 G5
2x Quad Xeon 3GHz
12GB PC2 6400 FullBuffered RAM
2x 4 Port NIC NC364T 1000T
HDD: * x 146GB 2.5" 10k
In a first part, each esx will hold 3 virtual servers.
In a first part of this project, the Vmware Environment has no requirement in
case of a module like HA, DRS, Vmotion, ...
We've 2 seperate esx systems.
2x VmWare Foundation
(include consolidated backup, update manager, ...)
What for a backup solution would you prefer?
We use BackupExec 12 on a different physical server.. I've already test the backup possibility.
I've install the backup exec vmware component and the vcb module from vmware.
Everything works fine so far in a testlab - i can backup the virt-machines directly from a
esx server. We've no central storage like a netapp (iscsi, san, ...) available.
Do you have experience in practical environment with a solution like this?
From my side a negative aspect in this szenario -
you will backup trough the same network adapters.
In a szenario like this, is vCenter necessary?
In my testslab i've found out, that it would work fine without it.
vCenter was only necessary for ha cluster, dsr, update mgr, ...
So you can save some investement - What you mean?
I've read a lot about different szenarios. Raid 10, Raid 5,
... don't use a Raid1 only for the vmware - wasting disk slots...
A DL380 supports 8 slots for 2.5" hdd's.
I'm planning to use 72gb 10k/15 or 146gb 10k disks.
In summary, I need around 100GB of diskspace (more better) on each ESX servers
for my virtual machines. The system should be sized for additional growing in future.
So a possible sizing was to use 8x 72gb disks with a raid 5 => around 500GB of space.
What do you recommend to use ... 10k or 15k? Is there any noticeable different?
Or do you advise to use different raid systems?
So during my websearch, I've notice, that a started esx server will not use
a lot of disk i/o - so it would be possible to install everything on 1 single raid sys
- what you think about?
Thanks for helping me.
