Storage: Opinions

In a recent review, I consolidated FC and Ethernet networks using FCoE (fibre channel over Ethernet) and Cisco's new Nexus 5000 switch. As the review showed, the combination merged the two transport protocols easily, allowing FC frames to channel through a 10G connection without giving up features or performance.

Of the assortment of technologies swarming around the storage and data protection space these days, one that can be counted on to garner both lots of interest and lots of questions among users is deduplication. The interest is understandable since the potential value proposition, in terms of reduction of required storage capacity, is at least conceptually on a par with the ROI of server virtualization. The win-win proposition of providing better services (e.g. disk-based recovery) while reducing costs is undeniably attractive.

Healthy debate is often necessary to get a balanced view of an emerging technology. Somewhere between endorsements and detractions, a realistic understanding of the long-term outlook for a technology arrives. As such, I have decided to turn to a guest once again for the second installment in what I hope to be an ongoing debate over the merits of flash SSDs (solid-state drives).

Being an optimist, I like to think that storage management is or will be getting better. It's hard, however, to ignore the fact that many admins don't know much about what's going on in the storage boxes they are sitting on. And it's not their fault, as management has been the Cinderella of storage apps for many years, and she hasn't found a prince to rescue her quite yet.

Everyone always worries about backup, backup, backup. Guess what? None of your users, or managers for that matter, care one bit about backup. All they want is restore, and they want it immediately. So shift your focus from backup to restore.

Would you pay several times more for a technology that yields only dubious performance advantage? How about if that technology is experiencing a high rate of product returns from early adopters?

I have a nightmare vision of storage administrators becoming clones of the mail carrier Newman from the TV sitcom Seinfeld, who once bemoaned the endless pressures of his job, crying, "The mail! It just keeps on coming and coming!"

Creating an effective backup for Windows is a challenge -- largely because the OS lacks a powerful, simple tool like Linux's dd, for example. However, there are many options for establishing a worthwhile backup system for Windows, some of which are free or rather inexpensive.

As the old saying goes, "When you're holding a hammer, everything looks like a nail." For me, this means more than just seeing a storage angle everywhere I look. Lately, it also means seeing the environmental impact of every product I review.

For some datacenter operators out there, insufficient server processing power isn't driving them to adopt more and more servers. Rather, it's the lack of precious server memory, necessary to deliver results at the lightning speed users have come to expect -- nay, demand -- from search engines, social networking sites, e-commerce sites, and similar Internet-based applications. A pair of companies, Virident and Spansion, have announced a remedy to the problem: replacing (or, more accurately, supplementing) the traditional DRAM found on servers with a flavor of flash memory called EcoRAM, capable of boosting a single server's memory beyond today's 32GB limit to a capacity of 512GB -- without increasing the machine's power envelope.

Reaping the fat savings of thin provisioning may have gotten a little easier, as IBM this week announced new features for managing SVC (SAN Volume Controller). And depending on your strategy for implementing SVC's new thin-provisioning capabilities in your storage environment, the news could come with a green lining.
