Doesn't sound too demanding -- why did you go with the expensive rigs? Management features?

Actually..we are planning to ramp up our VDI deployment and essentially double what we have going from 300 to 600 users stations.

There will be Oracle and SQL databases, some with a high transactional rate.

We also have many production servers that need to be consolidated.

I haven't had the opportunity to use Pools as of yet, will be setting that up with the VNX..still using RAID Groups on the CX-240 but when you add disks you have the option to go MetaLUN or add and restripe. You can't do that with Pools? I know that you don't have the 16 disk limitation like you have with RAID groups.

so far there is no option to restripe when using storage pools. and from what I understand if you have a 20 disk storage pool and want to grow it, EMC recommends you add another 20 disks. When you want to grow that 40 disk pool later they recommend you double it and add another 40 disks. They want the disks to grow by x2 each time because it can't restripe.

Caveat #4

Design Consideration / Caveat #4

From this, the recommendation to expand storage pools would be expand it by the number of disks it was initially created with. So if you have a 15disk storage pool, expand it by another 15disks so the new data can take advantage of the wide striping. I have also heard people recommend doubling the storage pool size as a recommendation, but this may be overkill. As an example, if you have a 15disk storage pool, and add another 15 disks to it, you could theoretically have some hosts I/O striping their data over 30 disks; so should you now expand this pool by 30disks instead of 15? And then 60 disks the next time? As always, understand the impact of your design choices and performance requirements before making any decisions as there is no blanket right/wrong approach here.

Hopefully EMC will introduce a re-balance feature to the pool like what exists in the latest VMAX code to alleviate most of these issues. But until then, these are some things to be aware of when designing and deploying a Storage Pool based configuration.

What IOPS load are you planning for? If you're not interested in the management features, I'm wondering why you spent the money on a managed solution.

Who said i'm not interested in the Management features? Read my posts above. I've explained why we chose this system.

Worked on some cool stuff this week. I am currently building a new storage server with a PowerEdge 2800 and a new ESXi host with a Dell T710, dual CPU and 32GB RAM:eek::D

I will post some pics later.
 
Just got back from the Data center @ the hospital, and at the door to MANLAND i see 2 packages one baggie of cat5 patch cables & my new patch pannel. :)

Just scored an APC rack on the cheap, has a bent panel but otherwise in pretty much perfect condition. Only lame thing is I just bought 2 sets of those UPS rails lol. Oh well.

I recently finished a project at work re-cabling all of our spaghetti closets with 1ft cables from Monoprice. Over 1200 cables in total. I definitely wasn't doing those by hand.

How many were DOA? We did a small (around 100) order and received 2 DOA.

Just one that I remember. My biggest complaint was that some of the 10-packs were not packed uniform so it took longer to unpack them. I had a system down to open all ten at once. I wish they offered non individual wrapping for large orders.

Thats exactly one of our reasons. The support from EMC is great and the VMware integration. They are in bed with each other so you won't have the blame game as much if you do have an issue.

I also loved Compellent's tiering and the way they handle data redistribution when adding additional trays. EMC seems to suck when I I try to add recently purchased disks to a storage pool.

Funny though, never been to so many sporting events/lunches from both Dell and EMC with them trying to win our Storage budget for next year.

don't get me started on EMC...their offering with the VNX is so far behind other vendor it's not even funny anymore. By adding disks to a storage pool..you must at least double up the original number..otherwise you will create the biggest hotspot you're ever seen.. and even if you do it properly..you'll always get the performance of the original # of disks..so if you've made a mistake..there's no way you can add performance to a storage pool.

All of their new functionnality is based on using storage pool...but once you buy the system..the first thing they will tell you is to not use storage pool because of the huge performance impact...and btw their thin provisionning is not working.

The VNX is just a CX4 with a shiny cover...that's it.

We went Compellent and we're not going back ever.

Just sharing some fact that me not be known by everyone currently San shopping..Far from useless...it's not like you can switch San vendor easily.

I don't hate Emc...in fact, their vnxe serie is really good...and could be the best offering at this price point.

Wow. Way to be an asshole. :rolleyes:
Your statement wouldn't have anything to do with the EMC training on Jan 10th 2012 that you are advertising in your signature would it?

Peoples real world experiences with technology is invaluable. Good or bad.

No, not really. but to say a product is crap, because he doesn't know how to support it isn't really necessary either.

sounds to me like you're an EMC fanboy and took his statement personally.
maybe take it with the grain of salt that it was meant as.

Opinions are like assholes, everybody's got one. One isn't any better or worse than the other.

True, kinda..

Not really a fan boy, because never worked on one, BUT just spent the last 2-3 weeks doing training, then doing the hands on stuff in January, that doesn't mean ill be a pro or a know it all.

However when walking through a HUGE medical data center and see emc all over the place, you kinda get the feeling that they are good, or else no one would use them.. Correct ?

If the Military, hospital Government RCMP etc etc uses it, you would think it's good stuff..
 
I got the feeling that EMC is the best at taking people to lunch and golfing trips.

Not sure, I've seen tons of people driving H2's and H3's in the past, and those are big piles of dog shit. This goes back to things your mother would tell you when you were a child. If all of your friends go jumping off a bridge, are you going to follow them?

Just because everybody uses something, does not mean it's good or the best. It just means people are using it.
