Choosing Between Monolithic and Modular Architectures – Part I

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 called Enterprise storage array.  Hu Yoshida discusses ...

Enterprise Computing: USP-V – So Long And Thanks For All The Fish

So HDS’s announcement has turned out to be a complete disappointment.  What it’s not: It’s not new hardware. It’s not providing more physical capacity. It’s not providing dynamic tiering. It’s not providing enhanced replication technology. What is on offer is the ability to cluster USPs – a feature called Hitachi High Availability Manager.  By cluster, this means connect two USP ...
