SRM 5 works! What a letdown.

This week we successfully tested SRM 5 and guess what? It worked.  We failed over, everything worked without a problem.  We failed back and guess what?  It worked again with no problems.  Not just the SRM "Test" we did a full-on "fail over" and "fail back."

This is all very anti-climatic for me. Our road to a working DR site has been a very rough, long, stressful, frustrating experience. We dealt with so many problems along the way; staff cuts, SRA problems, professional services problems, replication problems, failed WAN upgrades, etc... I should be excited, I should be jumping for joy.  A huge weight has been lifted off my shoulders. It's not fully configured yet, but the fact the we tested with no problems is a huge step in the right direction. However, i'm not super excited. I'm more aggravated that it took so long to get to this point.  Maybe after we have it fully configured and run production out of the DR site for a day or two will I be excited.

So what's the key to this working with no problems?  Nimble Storage. Yep, I replaced my storage to get all this to work without a problem.  It's all because how they perform snapshots and therefore replication. With our previous vendor we were 1-2 days behind on critical data.  Now with the Nimble we are 1-2 HOURS behind on critical data and 1 days behind on all data.  Yes, we are replicating our entire infrastructure daily.  All over the same 10mb MPLS pipe which is limited to 3mb during the day for replication traffic.

I would highly suggest you look at Nimble even if your not looking for a SAN replacement.  I wasn't looking to replace my SAN, in fact I was pretty dedicated to Compellent before my latest round of problems. Nimble does everything they say it does, it does it well and at a cost that is about the same as keeping my Compellent over the next 3 years.

If you are looking for a good deal on some Compellent gear let me know.  I have three Series 30 controllers,  1 shelf of Sata, 1 shelf of fiber and 2 shelves of SAS.
