Testing Compellent Replay Manager 7.8

Testing Compellent Replay Manager 7.8

So today I found the Replay Manager 7.8 bits to download.image

As is was awaiting this eagerly (see Off Host Backup Jobs with Veeam and Replay Manager 7.8). So naturally, I set of my day by testing Compellent Replay Manager 7.8. I deployed in on a 2 node DELL PowerEdge Cluster with FC access to a secondary DELL Compellent running SC 6.7.30 (you need to be on 6.7).

The first thing I noticed is the new icon.

That test cluster is running Windows Server 2016 Datacenter edition and is fully patched. The functionality is much the same as it was. There is one difference and that if you launch the back upset manually of a local volume for a CSV and that CSV is not owned y the Node in which you launch it the backup is blocked.

This did not use to be the case. With scheduled backup sets this is not an issue, it detects the owner of the CSV and uses that.

Just remember when running a backup manually you nee to launch it from the CSV owner node in Replay Manager and all is fine.

Other than that testing has been smooth and naturally we’ll be leveraging RM 7.8 with transportable snapshots with Veeam B&R 9.5 as well.

Things to note

Replay Manager 7.8 is not backward compatible with 7.7.1 or lower so you have to have the same version on your Replay Manager management server as on the hosts you want to protect. You also have to be running SC 6.7 or higher.

Wish list

I’d love to see Replay manager become more intelligent and handle VM Mobility better. The fact that VMs are tied to the node on which the backup set is create is really not compatible with the mobility of VMs (maintenance, dynamic optimization, CSV balancing, …). A little time and effort here would go a long way.

Second. Live Volumes has gotten a lot better but we still need to choose between Replay Manager  snapshots & Live Volumes. In an ideal world that would not be the case and Replay manager would have the ability to handle this dynamically. A big ask perhaps, but it would be swell.

I just keep giving the feedback as I’m convinced this is a great SAN for Hyper-V environments and they could beat anyone by make a few more improvements.

DELL EMC Ready Nodes and Storage Spaces Direct

Introduction

Unless you have been living under a rock you must have heard about Storage Spaces Direct (S2D) in Windows Server 2016, which has gone RTM in Q4 2016.

There is a lot of enthusiasm for S2D and we have seen heard and assisted in early adopter situations. But that’s a bit of pioneering with OEM/MSFT approved components. So now bring in the DELL EMC Ready Nodes and Storage Spaces Direct.

DELL EMC Storage Spaces Direct Ready Nodes

So enter the DELL EMC ready nodes. These will be available this summer and should help less adventurous but interested customers get on the S2D bandwagon. These were announced at DELL EMC world 2017 and on may 30th they published some information on the TechCenter.

If offers a fully OEM supported S2D solution to the customers that cannot or will not carry the engineering effort associated with self built solution.

I was sort of hoping these would leverage the PowerEdge 740DX from the start but they seem to have opted to begin with the DELL 730DX. I’m pretty sure the R740DX will follow soon as it’s a perfect fit for the use case having 25Gbps support. In that respect I expect a refresh of the switches offered as well as the S4048 is a great switch but keeps us at 10Gbps. If I was calling the shots I’d that ready and done sooner rather than later as the 25/50/100Gbps network era is upon us. There’s a reason I’ve been asking for 25Gpbs capable switches with smaller port counts for SME.

Maybe this is an indication of where they think this offering will sell best. But I’d be considering future deployments when evaluating network gear purchases. These have a long service time. And when S2D proves it self I’m sure the size of the deployments will grow and with it the need for more bandwidth. Mind you 10Gbps isn’t bad even if if, for Hyper-V nodes would be doing 2*dual port Mellanox Connect-X 3 Pro cards.

Having mentioned them, I am very happy to see the Mellanox RoCE cards in there.That’s the best choice they could have made. The 1Gbps on board NICs are Intel, which matches my preference. The game is a foot!
