This is a series of posts that cover the features of Hitachi’s new enterprise storage platform, the VSP (Virtual Storage Platform), also sold by HP as the P9500 array. Previous posts:
Hitachi Virtual Storage Platform: Disk Drive Architecture
Hitachi have modified the VSP array to provide significant performance improvements over the previous USP [...]
The recent proposed acquisition of 3Par by Dell and/or HP has made me think a little more about the direction the storage industry is taking in terms of their storage array design architecture. Since storage arrays became a category of devices in their own right, we’ve seen the growth of the monolithic, sometimes [...]
Here I am again on the start of another vendor blogging day. As the title of this post suggests, this will be a trip to see Hitachi, or HDS (Hitachi Data Systems) if you prefer. The Bloggers Day is taking place over two days and is located in San Jose, just south of San Francisco [...]
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.
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 of [...]
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 [...]
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, storage resources can be [...]
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 [...]
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 to ‘zilla for pointing it out. [...]
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 on whether USP/UVM can [...]
