Depending on the age of the arrays and depending on the software sitting on the arrays and especially if the arrays were out of warranty periods; the maintenance costs are generally so high that it simply does not make economic sense to keep them around.
Wide-striping is now just another feature; itâ€™s a very important feature but just another feature now. 3Par took wide striping and made it useable; EMCâ€™s historic implementation using metas and hypers was painful and with the large arrays of today it becomes a full time job to performance manage an array. 3Par made it easy and much kudos to them for doing so. I think 3Parâ€™s legacy will be the ease of management that they have brought to the Enterprise array (and thin provisioning).
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.
While the bulk of Sun-related news this week relates to reported talks of a buyout by IBM, the company took a break from negotiations to introduce their own cloud computing and storage infrastructure, challenging Amazon, Google, Rackspace, and perhaps VMware, Microsoft, and Nirvanix.
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!
Is the adoption of a unified fabric an inevitability? If so, will it be FCoE or iSCSI that leads the charge?
Enterprise arrays have been successful because they offer high reliability and availability. This was achieved through monolithic designs of high cost components and a focus on engineering quality. That was then – now we have much more reliable components – disk drives really donâ€™t fail that often – SATA drives are much more reliable than they ever were.
Although I give the various players a hard time; the industry doesn’t do everything badly and I try to see the positives as well as the negatives. So I was thinking about the perfect array and what features I would like to see!
Previous posts have discussed reasons for migration and the need to identify all of the servers accessing your storage resources. In this post, I will cover the need to perform a full inventory of connected hosts and the gap analysis work to be performed before migrations can start.
We all agree that EFDs have a place in the storage infrastructure of the future but we also have to ask ourselves what is this infrastructure is going to look like? If we look at some of the press releases and comments with regards to Fusion-IO, you would probably believe that the SAN was on the way out or actually shared storage in general would die.
