UNSOLVED
Whats the difference Clarrion v Celerra
Hi All,
Our company is doing its tech refresh next year. One of the items to upgrade is our CX3-20c. I had been suggesting that we move to the cx4-240, but our vm guys are pushing the celerra. From my understanding the Celerra is a Clariion with a all in one switch\server interface at the frnt end. To me this sounds like a very beefy NAS box.
Ingoring the Sales the guys got today just after peoples thoughts on the following questions
1./ "My" office is mainly a application\DB Server setup. We are finding that only small front end application servers are being housed on vmware (even some of those are getting reviewed) and we have stand-alone DB's (2 and 3 ru servers..heaps of cpu, heaps of memory blah blah). I'm struggling to see the benefit of Celerra in this situation..i would have thought with the standard zoning and lun presentation of a Clariion provided a high level of server. Is this the case
2./ I read the various EMC Celera Unified solution for Microsoft Sql. They all seem to refer to iSCSI. It has been a while since I studied iSCSI..but U though it wasn't as effective as a FC connection.
I suspect I'm resisting change because it is unknown..but any comments would be great. I also tried to get a Symmetix..but that was scraped as it would have to go were the beer fridge is now.
Cheers

I think was confused between the FLARE 30 and Unisphere announcements and some marketing lingo. I just did a little bit of digging and I was incorrect on that. But if you aren't looking to do NFS but iSCSI for your VMWare infrastructure and FC for your DB hosts then the CLARiiON is the way to go since the beer fridge is in the way of deploying a Sym. The CLARiiON comes with iSCSI ports in addition to the FC ports so you can do both with a CX4.

Dynamox,
Isn't both an option now with FLARE 30 coming out any minute now? I thought that with FLARE 30 on the CX4's we would have the option of enabling/deploying both abilities of the CX4 platform. Or did I get one of the slide decks from EMCWorld confused?

hahaha...are you serious ?
Hey, I don't know about you but that is the best place for the beer fridge: in the data center. Nice and cool in there. That is a hard decision to make, beer fridge or symm.

Hi Guys,
Thanks for your responses. It seems, at least from my point of view, common sense has one the day. CX4-240 * 2 will soon be on order.
Although I have moved to fridge to the other data centre room the sym is still a no go.
Now it is on to Blade vs Rack mount servers…
Cheers

As you probably have read, Celerra is a multi-protocol platform, it can serve storage via CIFS, NFS and iSCSI protocol. You have an option of getting a FC-enabled unit that can serve regular FC storage, just like your regular clariion. Some shops (including us) connect NFS storage to vSphere to use as datastores. While it may not provide the same performance as 4G FC connection but for low i/o VMs it works great, you save money on not having to burn ports on your fiber channel switches. When 10G Ethernet switches become cheaper ..it may be even better connectivity option for vSphere. Celerra is also great for consolidating windows file server.
