Re: Re: Help with DR setup for VMware 5.5 environment

On the EMC unit, would we have to use the Mirror View10GB interface for replication communication or would it use the current SP management interfaces?

Re: Help with DR setup for VMware 5.5 environment

Nah, Since you are going to use RecoverPoint from the previous threads, RP would handle all the replication and Mirrorview wouldn't be used. It's not even needed on the array nor should it be enabled if you plan to use the VNX splitter with RecoverPoint from the release notes:

Re: Help with DR setup for VMware 5.5 environment

The vRPA will communicate with the VNX using the SP management 1G interfaces or would i have to re purpose one of the  10G ports that I showed above?

Re: Re: Help with DR setup for VMware 5.5 environment

The vRPA communicates with the VNX to do the splitting over iSCSI - so there has to be iSCSI ports configured on the VNX for use with native iSCSI - either 1Gb or 10Gb. These don't have to be the mirrorview ports, but since you mentioned it, mirrorview should be disabled on the array and once that is done, you an either re-use those ports or use any of the other iSCSI ports (1Gb or 10Gb) you have available for the iSCSI requirements of RecoverPoint.

Re: Help with DR setup for VMware 5.5 environment

Now its starting to click.. I want to thank you for all of this great information.

I'm looking over the website to see how use the RecoverPoint Licenses that I was given. Not sure if its a matter of downloading the OVF file and having to apply some license to it.

Currently have the VNX targeting a couple of LUNs via multipathing using 2x 10GB iSCSI per SP.Will I have to run multiple vRPA because of the multipathing? The question of how resource intense these vRPA came up in discussion as well.

Re: Help with DR setup for VMware 5.5 environment

The RP license will be a LAC file from EMC that is simply uploaded through the RP GUI once the cluster is formed and running (just point it to the file and it will load what you are licensed for - it is the very first screen you will see once you log into the RP GUI for the first time).

The multiple vRPA's aren't required due to multipathing, it is a cluster requirement to have a minimum of 2 in a cluster (4 if you have a DR site since each site is a "cluster" with RP). The resource load of the vRPA's will vary depending on their load since they will essentially act as any other VM on your setup...they will only scale so far depending on what type of vRPA you deploy (small/medium/large). I'm not sure if there are some overhead numbers in the release notes on the vRPA's or not...I'd have to check. If there are no bottlenecks in the setup to begin with, it shouldn't be overly noticeable.

Currently I have two dedicated iSCSI ports on each SP for iSCSI via multipathing for the VMWare environment.

In order for the vRPA to handle the splitting, will I have to enable another iSCSI interface on each SP? Is so, would this have to reside on its own network range separate from the current production iSCSI networks?

Thanks

Re: Help with DR setup for VMware 5.5 environment

As long as they are segmented from the vRPA LAN/WAN, they can be shared with host traffic (NOT anything related to Mirrorview though) at the trade-off of possible performance degradation since they are shared interfaces. The key point is to ensure they are segmented from the LAN/WAN interfaces you would configure. Take a look at the Deploying vRPA Technical Notes on support.emc.com - that should detail the implementation process well. Best Practice would ideally have them separated for ultimate isolation for performance and scalability.  RPA1.jpg

ISCSI1 & 2 are referring to the multipath iSCSI networks correct?

Currently have the following setup for the iSCSI:

iSCSI1: 10.160.19.224 /27

iSCSI2: 10.160.19.96 /27

Both on separate VLANs.

I was thinking of extending those VLANs to the current 10G interface I have setup for general VM Networks.

The LAN for RPA can be on the same network as the ESX MGT/VNX SP MGMTs?

Re: Help with DR setup for VMware 5.5 environment

LAN can be on the same as the ESX/VNX - won't be a huge amount of communication going on there.

As for iSCSI, you should be OK with how you have them setup from a VLAN perspective.
