I was thinking of having the following setup....i could of got it horribly wrong
We will be having 2 x 7110s mirrored for DR. Linked to these via a SAN only network would be 2 x Sun 4160's with 32GB RAM. Running on these will be ESX VI3.
I was going to create 2 projects on the 7110. One holding the NFS shares for my VM images and 1 holding my shares using CIFS for users documents.
I am a bit confused of when exactly I need to use iSCSI for block level access. A couple of the VMs will have databases on them (not SIMS, thats staying stand alone). Do I need to setup a LUN for the VMWare image AND a LUN for the d: with the data on it or can I just get away with having a LUN for D:? and still using NFS for windows. I assume doing it either way I will have to use the windows iSCSI tool.
How does that setup sound to you guys?
Your other option would be to use replication, but I haven't played with that yet so can't really comment.
Get hold of the simulator and do some playing, it's the best way to understand what you can do.
Thanks for that,
I have had the simulator playing with it and it definitely does help.
I am going to draw up a diagram of our proposed whole setup and hopefully people could have a look and see if there are any problems with it or amendments to improve it.
One thing I need clearing up is the amount of storage you get left with on the 7110 (2TB) - am I right in thinking: -
146GB x 14 Drives = 2044GB
Two of the drives are mirrored as the system disks: -
2 x 146 = 292GB loss
Then if you go with RAID5 Double parity: -
~ 2 x 146GB = 292GB loss
Then you have one drive as a spare
So 146GB loss
So you will have about
1.3TB worth of usable storage to then split up
Is that right?
The 7110 actually has 16 disks - 2 are used for the OS and the other 14 are for you to use for storage . Currently got mine setup with the ZFS raid-6 equivalent giving me 1.4tb of usage storage.
You can config it as RAID 5 as well can't you to give you more like 1.6Tb storage?
you should consult your backup software documentation to be sure.
Thanks, Symantec Backup Exec seems to have the option so will have to see if that’s a possibility.
I can't get the simulator to work on Virtualbox, it starts to boot then says that it can't update the microkernel then restarts. Is there an option that I need to set on the VM or mimimum RAM requirement? or an FAQ even?
How much memory have you given it? (It defaults to a gig when imported if I recall correctly).
Not enought then I'll give it a real amount
I have just created a fist draft of our proposed solution with the 7110, and 2 x X4140s and knocked it up in Visio.
The set up is splitting the 7110 into two using a LUN for our ESXi VMWARE images and a CIFS share for storage.
There is a private network for the SAN / iSCSI bit
I have left quite a few labels off and also the networking of the management interfaces.
I have attached it as an image – any feedback would be appreciated.
You may want to do this in stages and check the performance, should be fine though with that amount of VM's.
I have been as ked by many of you how and when we plan to impliment User Quotas on the S7000 range.
I can now point you at the OpenSolaris.org website and to a specific public domain reference. Now this relates to ZFS but as you all know we are using ZFS under the covers as the file system for the S7000 so it kind of makes sense that stuff that appears in ZFS gets to appear in the S7000 appliance. I must add though that not all stuff appears straight away and sometimes stuff won't appear but please do not be disheartened. The guys that develop this stuff has brains the size of planets and come up with some really good stuff that makes the S7000 such a cool piece of kit.
Anyway, enough rambling.... here's the URL http://arc.opensolaris.org/caselog/PSARC/2009/204/mail
Any questions then please come back to me. Don't email the guys on the OpenSolaris page as I'm trying to give a single consistent message back into the development team.
