I am about to embark on a similar project and was wondering if you have any feedback on the DS3500 in this configuration?
I was considering a similar configuration ie Dual Controller DS3500 with 2 x ESX nodes connected via SAS (redundant config 2 x HBAs in each ESX node).
Any feedback would be appreciated.
even if server is directly connected to the storage array, you need multipathing.
provide two paths to each lun will provide you redundancy on path failover. you can check from the stroage end side.
Is that a roll out you have completed? Did you write the how to? How do you find the performance of the solution?
So many questions....
Yes I wrote out the procedure.....after much trial and error experimentation and intensive reseach.
It is a good practice to document such configurations for future reference...
As for the performance....works fine.... no problems encountered so far.
I am glad this helped!!
I have got this project under way now and have run in to a small problem. I have two ESXi (4.1 update1) hosts (x3650M3) both with 2 x SAS HBAs similar to your documented install. I have connected,
HBA1 to SPA1
HBA2 to SPB1
HBA1 to SPA2
HBA2 to SPB2
When I boot either ESX node, straight after POST as the ESXi embeded is about to boot the Light path diagnostics lights up for MEM and CNFG. Everything seems to work OK however the DS3500 complains that 3 of my LUNs are not hosted on their preffered path. It turns out that I cant present any LUNs from SPB and all LUNs revert back to SPA. I have placed a call with IBM but just checking to see if you came accross a similar issue?
I'm in a design of same setup. 2 x X3650 and 1 x DS 3524 ( SAS) so i can use this as shared storage?Curious1, Any Image of the setup?
