HDS: Hitachi Data Systems Introduces Breakthroughs in Storage Cost Savings and Dynamic Provisioning

Personally, HDS' recent announcement is extremely more exciting than their rollout of clustered heads.

Most of it is just plain nice. Like EMC, HDS can now drain the pool. This allows you to remove space from your Thin/Virtual/Dynamic Pool if you have sized it too large. Personally, I've become a fan of just making all of the disk in the...

Recently one of the performance folks at the site I work out came to me with a question. He was putting together some numbers for disk performance and had come up with an interesting issue.

The intergalactic standard formula for average disk access is:

Average seek time + Rotational Delay + Transfer Rate of Data + Controller Overhead

Looking at EMC’s specification sheet for the new V-Max, we get the following values for

450GB Fiber Channel...

Recently, I purchased a very expensive mac book for my wife. This greatly increased the complexity of keeping data backed up, as previously I had just backed up my computer to a USB Hard drive.

I had a few complex data sets to protect on my home computers:
1. Pictures and Video. Every picture of both of my kids and every video is kept on my hard drive.
2. I can't remember the last time I did a tax return that wasn't on the computer. The printouts of all of it? Sitting...

The heavyweight management tool in the industry is EMC’s Control Center. This software package allows you to monitor, manage, and configure all aspects of your SAN and associated storage nodes. With a large amount of support for many vendors not EMC, this product can be your one stop shop for your needs.

Then why do many EMC engineers not use it when provisioning storage?

1. They’re not used to it. When you’ve done everything command line you already have...

Hitachi Data Systems recently announced HAM. A pork product? No. HAM is their cluster technology for their monolithic storage.

What the heck does this mean or do? Honestly? Who knows! This product announcement was barely more than a few paragraphs on a news page. From reading into the HDS blogs and others, this is what I have gathered:

HDS USP-V arrays can be clustered to be made aware of each other. Think NetApp (And any Hitachi engineers reading this just...
