I have little experience with storage EMC and I would have a couple of questions about the use of vSphere 5.5 with CLARiiON CX4 storage 120 and vnx5200.
Both the storage are connected fiber channel.
I have to update my infrastructure to vSphere 4.1 to vSphere 5.5.
My infrastructure is composed of 3 servers DELL, one CLARiiON CX4 120 and a EMC2 VNX5200.
First I saw that the Clariion CX4 storage 120 does not support VAAI with vSphere 5.5 while the storage vnx5200 supports it.
So, since I want to use archiving VAAI on VNX 5200 and I can not use it on the Clariion CX4 (as VAAI is not supported with vSphere 5.5).
I like I do?
I leave the failover mode to 1 for the CLARiiON CX4 120 and I configure the failover mode 4 for vnx5200?
It is correct to use the round robin for multipath for vnx5200?
I will use multipath vmware.
It makes sense to set iops from 1000 to 1 as per article vmwarehttp://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=206935... ?
If I leave the failovermode 1 for clariion CX4-120 emc and then as multipath should I choose MRU is a solution supported by EMC in vSphere 5.5?
If your VNX 5200 is running Flare 28.5 patch 704 or later then AULA (Failover mode 4) is your best option. Please see here for further clarification https://community.emc.com/message/598465
Ensure that your SATP is set to VMW_SATP_ALUA_CX
Personally, I would leave your IOPS setting to 1000 (default) unless you see performance issues or an EMC advisory for your VNX 5200 suggests otherwise.
I would also leave your PSP to Round Robin but this depends on your own requirements. There is also in-depth information on the link I posted above.
Thank you for your answer.
Regarding the VNX it is fully understood.
The VNX and clarioon are connected to the same vSphere cluster.
My question is how do I configure the clarriion CX4?
