Unified Storage Problems?

NetApp’s unified storage platform is a compelling vision for a customer; one platform to support pretty much all your storage needs. It is a powerful sell, it is still pretty much a USP for them; everyone else has to fake it by glomming together storage products and pretending.

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.

Enterprise Storage?

Myself and Tony Asaro have had a bit of snit over the uniqueness of the USP-V; he opines that it is unique and I am right that it is not unique. In many ways, this comes down to Tony’s opinion that the USP-V is unique because it is the only external storage virtualisation array which is Enterprise Storage. In his opinion neither the v-Series or the SVC are Enterprise Storage and hence do not compete with the USP, DMX and DS8K range. Also in SVC’s case because it does not have it’s own disk and simply virtualises external arrays; it is not a storage device (I’ll leave that comment alone).

HDS High Availability Manager: How It Works

HAM combines conventional ingredients to create a whole new flavor

It has been two days since HDS introduced High Availability Manager (“HAM” to us), disappointing some and confusing others. Now that the dust has settled some, it has become clearer just what HAM is and how it works, and we come away more impressed. HDS has taken simple, proven technologies (path management, clustering, synchronous replication) and remixed them into a super-high-availability solution for the largest enterprises. Perhaps this is not what many expected, but it’s certainly a worthwhile addition to the company’s family of products.

HDS’ HAM-Fisted Announcement Can’t Be All

HDS telegraphed that a big announcement was coming today. They even made it fun, with a (literally) cryptic blog entry to make sure we were all watching. But the announcement of High Availability Manager, a software product to manage existing HDS USP-V and USP-VM arrays, underwhelmed. It isn’t HDS’ answer to the EMC Symmetrix V-Max and it’s forthcoming FAST technology.

EMC Symmetrix V-Max Is Neither Monolithic Nor Midrange

The V-Max Engine looks a lot like a CLARiiON CX-4 UltraFlex DPE

EMC today announced a new generation of the flagship Symmetrix enterprise storage array by EMC: Initial reactions have compared it to the CLARiiON (with which it shares hardware), the DMX-4 (with which it shares software), the new 3PAR F-Class, the Compellent Storage Center, the HDS USP, and NetApp’s next-generation clustered filers. In every case, the V-Max is different enough to be compellingly new – it’s a true hybrid of monolithic (tiger) and modular (lion), thus its codename, “tigon”!

Storage Virtualisation and Commoditisation

HDS’ Hu makes a point in his latest blog entry in that Storage Virtualisation allows the end-user to turn commodity disk into enterprise disk by sticking it behind a virtualisation appliance; in Hu’s case, he’d deeply love that to be USP.

Bigger Blue?

IBM were always going to go acquisitive this year and it’s no surprise to me that the first target appears to be Sun. As other commentators have already pointed out, this is not a reaction to Cisco’s announcement on Monday but more a strike against HP. This is about being Number 1 again!

V is for value??

Put NetApp in because you want to use NetApp but don’t put it in to virtualise your existing environment unless you are prepared for a whole lot of work. If you simply want to virtualise and build a consolidated pool of disk, you might well be better looking at SVC or USP-V.

Hitachi’s (HDS) RAID 6

Hitachi (HDS) has been one of the pioneers in implementing RAID 6 in their storage products. This technology briefing covers HDS’ implementation of RAID 6 and compares it to their RAID 5 implementation.
