Im a fanboy for similar reasons.

Ill also admit we are a NetApp VAR, but I get to eat my own dogfood, so it’s 
the shiz.

I will be the NetApp fanboy. I love my filers, why?

 

Dedupe - I am getting about 33% space saving on my CIFS shares. This number 
will increase now that I have upgraded to a more recent firmware release and 
can combine volumes.

Snapshots - I am keeping 6 months of snapshots that allow for easy/fast data 
retrieval, at a cost of less than 5% of volume space

Replication - I am replicating between two sites, it only replicates the 
deltas. Nightly replication takes less than 5 minutes. I have created a share 
on the remote site for a read-only copy for the people traveling between sites.

Simplicity - They just work.

 

I need to rebuild my VMs on NFS and from what i hear 50+% space savings is the 
norm, 80% is not out of the question. 

 

Their software options can get rather expensive. The dedupe is free, almost 
everything else is a cost item. You need to decide which options you need, 
everything is a-la-carte.

The 20xx offer FC and iSCSI standard unless I’ve misunderstood (switch cost

The NAS thing, other than seeing a potential benefit in NFS, isn’t of much 
interest – I’m struggling to see a benefit running CIFS from a NAS rather than 
doing what we do now and having a VM as a file server?

 

One thing I am keen on is, as much as possible, keeping it simple – the old “if 
I’m not around” scenario.

Their feature licensing is expensive… FC connectivity for VMWare is cheaper on 
Dell/EMC, and for NAS connectivity, front-ending the EqualLogic boxes offer’s 
more bang for the buck.

Can you expand a little on “migrating away from NetApp primarily due to cost”?

 

Regarding the NFS question, only that I’ve heard a lot of good things about the 
flexibility NFS brings you and the fact you can expand and shrink on the fly so 
if you need 500gb for a VM to test something you can provision it and then 
reclaim it – obviously without the pricing I don’t yet know what sort of 
premium we’re talking.

We are using Dell sourced EMC’s for FC storage for our VM’s. We are migrating 
away from NetApp primarily due to cost.

 

We are spinning up EqualLogics as iSCSI targets for our file servers and 
backup-to-disk options.

 

Is there something that makes you want to lean towards NFS as a mount 
technology?

Looking for a little feedback folks.

 

We’ve got a SAN replacement coming up in a few months.  We’re pretty much a 
vmware shop except where a service has to run on a physical server (IO cards 
etc.).

 

The vendors I’m primarily looking at are Lefthand, Equallogic and Netapp, and 
possibly EMC since Dell can quote on an EMC solution as well as Equallogic.

 

I’ve not had quotes yet, but so far my instincts are leaning towards Netapp, 
mainly because of the things I keep hearing about NFS for vmware, as well as 
the fact they seem to offer a lot of flexibility whereas Lefthand and 
Equallogic offer iSCSI and, well yeah, they offer iSCSI.

 

Be interested to hear any experiences, especially around vmware and replication 
between SANs at live/backup sites (not a live failover site but a “this will 
take a little work but we have a copy of the data that’s an hour old” site).
