EMC DMX-4 and NAS

Hi,

I am looking for a NAS solution that can work well with an existing EMC DMX-4 SAN.  A lot of data that needs to come off the premium disk in the SAN and onto lower cost NAS storage, but still needs to be readily accessible afterwards (hence the NAS).

Given the age of the SAN h/w, something newer would be preferable when it comes to the NAS, e.g. EMC Isilon NL series, NetApp equivalents, etc.  I'm not looking to use DMX-era NAS, e.g. Celerra.

So, my questionS... :)....are:
1) Has anyone used any current NAS offerings with a DMX?  
2) What did you find to be the best way of migrating existing data from the DMX to the NAS? (i.e. are there any tricks to it?)
3) How did you handle existing fibre-attached clients creating new block data landing on the SAN that should ideally go to the NAS, i.e. replication/removal?

TIA

1) Has anyone used any current NAS offerings with a DMX?  
What you envision doesn't have any dependencies on the DMX platform. I have used EMC CLARiiON or VNX arrays as a cheaper tier of storage for a number of my customers. A VNX array has the advantage of offering both block and file storage out of the same array.

2) What did you find to be the best way of migrating existing data from the DMX to the NAS? (i.e. are there any tricks to it?)
If you were to use block storage on a VNX array, I'd recommend either PowerPath Migration Enabler for physical hosts (Windows, -NIX etc), Storage vMotion for VMware VMs or SANCopy for SAN to SAN copies. PowerPath and Storage vMotion are the least disruptive methods

3) How did you handle existing fibre-attached clients creating new block data landing on the SAN that should ideally go to the NAS, i.e. replication/removal
As above.

Hi,

Thanks for replying.

VNX is used elsewhere within the organisation (different country) which I helped deploy, but there's no way one could be used for this solution (long story!)

I'll keep the PowerPath solution in mind though, thanks for the suggestion.  Will keep the thread updated.

If you're simply looking for cheaper storage then there's no shortage of options including SAN and NAS. Start by working out how much performance you need and how much space you need. The performance will tell you how many and what type of SSDs and disks you'll need. And whether or not NAS is a sensible option.
