Thin Provisioning (Dynamic Provisioning, Virtual Provisioning, or whatever you prefer to call it) is being heavily touted as a method of reducing storage costs. Whilst at the outset it seems to provide some significant storage savings, it isn’t the answer for all our storage ills.
In case you haven’t noticed, the next chapter in the story of the unstoppable juggernaut that is VMware is here. It’s called VMware vSphere 4 (dropping the Virtual Infrastructure moniker) but is still essentially the same as the previous VMware with incremental improvements. The full story of what private and public clouds will be seems [...]

Marc Farley makes some interesting comparisons to storage purchasing decisions in a recent post. For the sake of disclosure, I do go to Costco and buy in bulk – no not 200lbs of chicken wings, but those things that can be divided and/or frozen (like salmon and coffee) – and more crucially things [...]
I spent some time today with the good folks at 3Par, as offered by Marc Farley a few posts ago. It was good to get more of a background on the product and also see what’s happening in the future (although I can’t talk about that!).

3Par finally floated on Friday this week. You can read the official announcement here. 7.5 million shares were released at a target price of $14 (about £7 in real money). In total, there are 60,015,700 shares of common stock now outstanding, valuing the company at a shade over $840 million. This [...]
So the rumours (here and here) are true. Here’s the announcement to prove it. HDS are going to support 750GB SATA II drives in the USP.
This is an interesting position HDS are taking as thin provisioning will be able to take use of the enhanced drive capacity [...]
I’ve had a quick look over the specifications of the new DMX-4 compared to the DMX-3. There aren’t really a lot of changes. The backend director connectivity has been upped to 4Gb/s and presumably that’s where the 30% throughput improvement comes from (with some Enginuity code changes too I guess).
There are a number of [...]
Hu posted an interesting view of storage utilisation here. His view is that virtualisation on the USP would improve on the average 30% utilisation. I have to say that I disagree with this. There are lots of reasons why storage remains unused in the enterprise:
inefficient administration by Storage Admins, SAs and [...]
I’ve been doing more VMware work recently. The deployment I’m working on is using SAN presented disk. The storage started as 50GB LUNs, quickly grew to 100GB and now we’re deploying on 200GB LUNs, using VMFS and placing multiple VM guests on each meta volume.
Now, this presents a number of problems. Firstly, it was [...]
