Enterprise Computing: Why Thin Provisioning Is Not The Holy Grail for Utilisation

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. What is...

Enterprise Computing: The New USP – A Dreary Storage Cluster?

Well, I truly hope not. Let me just explain what I’m talking about and things may become a bit clearer. HDS have started their viral marketing for an announcement being made on 27th May. Claus Mikkelsen’s latest blog entry asks us to guess what the announcement will be, based on an acronym...

Betamax

In case you don’t always go back and look at comments (and let’s face it, it’s not easy to track them), then have a look at Tony’s comment from my post yesterday. It’s good to see a bit of banter going on and that’s what HDS could do with. HDS have hardly developed...

Replacing the Virtualisation Component

There’s no doubting that storage virtualisation will prove to be a key component of IT architecture in the future. The overall benefit is to abstract the physical storage layer from servers either in the fabric, or through the use of a dedicated appliance or even in the array itself. Over time,...

CU Free

Does anyone use CU Free? Here’s the reason for my question. I’ve just implemented a migration from a pair of 9980V and 9970Vs to a single USP in one site and a 9970V and 9980V remaining in the other site. All of the MCU->RCU relationships (4 of them) are being used between the USP and...

Virtualisation Update

Thanks to everyone who commented on the previous post relating to using virtualisation for DR. I’m looking forward to Barry’s more contemporaneous explanation of the way SVC works. I guess I should have said I understand Invista is stateless – but I didn’t – so thank’s...

Using Virtualisation for DR

It’s good to see virtualisation and the various products being discussed again at length. Here’s an idea I had some time ago for implementing remote replication by using virtualisation. I’d be interested to know whether it is possible (so far no-one from HDS can answer the question...

Invista

There’s been a few references to Invista over the last couple of weeks, notably from Barry discussing the “stealth announcement”. I commented on Barry’s blog that I felt Invista had been a failure, due to the number of sales. I’m not quite sure why this is so, as I think...

DMX-4 Green or not?

After the recent EMC announcements on DMX-4, I promised I would look at the question of whether the new DMX-4 is really as green as it claims to be. I did some research and the results are quite interesting. Firstly we need to set the boundaries. One of the hardest part of comparing hardware from different...

HiCommand CLIEX

I’ve been using the HiCommand CLIEX (the extended CLI) today. It differs from the normal CLI in that it talks directly to the array via a command device and bypasses both Storage Navigator and Device Manager. HDS have needed this way of communicating with an array for a long time. On the one...
