Hi I am looking to procure a HP p2000 with two DL380 G8 servers. The P2000 and SAS controllers are on the HCL. I need to understand how I can present the LUN's to the two servers for HA. I have done this on ISCSI many times, but SAS is new to me.
I am looking for a guide to a bit of a How to. I do understand that on SAS you cannot present the same lun to two different hosts at the same time so how would you configure failover ?
Hi
This PDf would help you creat Host group of ESX/ESXi servers and assign virtual disks to host groups.
http://www.hp.com/hpinfo/newsroom/press_kits/2010/JustRightITopk/MSA2000_G1_White_Paper.pdf
once virtual disks are assigned to host groups in vmware cluster, rescan HBA over all ESX/ESXi.
Add storage > Disk/LUN ..you would see LUNs assigned to host... name the datastore.
Once added to one host. wait a while..and you would see the same datastore over other hosts in cluster.
I wrote it on old post and not sure you see that, so I will juste copy-paste ![]()
Like I said, this is a shared storage and you CAN present one volume on two or more servers.
P2000 come with one or two controllers, every with 4 ports, so you can connect directly servers on the same LUN and you don't need SAS switch.
If you have two controllers and two ports server SAS card, you have redundancy.
I implement exactly the same enviroment a few months ago and believe me, it works great.
