Chris Mellor posted a great article recently, speculating on the future of certain storage products. He hinted at a new high end array from EMC, presumably an extension to the DMX range – tentatively titled DMX-5.
We’re about due for a new hardware release. Looking back, the [...]
I’ve been looking at DMX configuration options this week. Essentially the question is how best to lay out a DMX-3 or DMX-4 array with a tiered configuration. For me there are two options and it’s pretty clear which I prefer. First a little background. The following diagram shows the way DMX drives are deployed within [...]
EMC made two DMX-4 announcements today. At the top end, the first details solid state drives which replace standard spinning HDDs. At the bottom end the second announces new 1TB SATA-II drives (and other miscellaneous stuff).
The solid state hard drive (or as Chuck Hollis describes it, [...]
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 [...]
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 that virtualisation in [...]
In a previous post on DMX-4 I discussed the use of SATA drives in enterprise arrays. A comment from our Storage Anarchist challenged my view of the resilience of SATA drives compared to FC.
Now unless I’ve been sleeping under a rock, the storage industry has over the last 5 years pummelled [...]
Thanks to Barry/Mark for their posts/comments on power usage. Call me stupid (and people do) but I can’t find the EMC Power Calculator for download on Powerlink as ‘zilla suggests (although I did find a single reference to it).
Can you post the link guys? Is it EMC internal only? If so, [...]
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 [...]
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 [...]
I’m glad to see EMC have upped the ante with their series of announcements today. I’ve not had time to digest them all but I did read Storagezilla’s refreshing post summarising a lot of the announcements. Once I’ve read things in a bit more detail then I’ll comment however, I like the [...]
