Yesterday I saw the new Dell Poweredge C-series servers, and they’re really DENSE!.
in my opinion they’re an awesome platform for Private and Public Cloud based on VMware, take a look at this picture:
It’s a 2U rackmount server that house 4 independent servers, each module is serviceable on its own, and each module hosts two Intel 5600 processor with a whopping 96GB of RAM.
Another fellow blogger Dave Graham already got his hands on it, check out it’s post and first-hand photo gallery here.
I saw an interesting discussion between Duncan Epping and others in the Virtualization Twitterverse and I was wondering how the claims of upwards scalability in the storage world are effectively true or just plain fiction.
I take, as an example, Hitachi and its USP-V: they claim that the USP-V can address 247 Petabytes of storage behind it (virtualized and internal), and that the storage can sustain 4 MILLION IOPS!. That’s pretty impressive! 
(even if you read their SPC-1 Benchmark report and see that with their best config they can reach just 200.000 IOPS but that’s another story).
Well, it’s not so impressive actually 
If you do some simple math you can clearly see that 247PB (maximum addressable space) divided by 4.000.000 IOPS (maximum IOPS achieved) give you a mere 0.01521 IOPS per GB, that’s really a NOT impressive.
So, even with the best configuration, best practices followed, best Tier 3 storage virtualized behind it you cannot squeeze the system to its maximum capabilities.
Considering that, I think that Monolithic storage is on a dead end railway, the Scale out approach is surely the way to go in the near future.
