In part one of this article, I lamented the state of our enterprise storage arrays and talked about the features we absolutely need on any new arrays bought this year. Why the lament? Because this is 2015, and we’re tired of the 1995 technology we’ve been using. When you send out your RFPs this year, the following are things you should score vendors on.

It’s 2015, but you would think it was 1995 based on what we’re still using in our data centers for enterprise storage. We still have gobs and gobs of spinning disks, sucking power and boring us to death while they find our data. Convergence is largely unconverged—we still have separate Fibre Channel and IP data networks, and the only things that got converged were our bills of materials and the sides of our wallets. And for some inexplicable reason, we’re still debating how and when to use flash.
A few weeks ago, I had the opportunity to get to know SolidFire and its Storage System product, an all-flash array designed for on-premises use but with some attractive cloud functionality. At first glance, the array looks like many of those in the all-flash space. It’s built out of discrete nodes; uses 10 Gbps networking to present iSCSI; does inline deduplication, compression, and best-effort real-time background replication; has copy-on-write, space-efficient snapshots; and scales linearly.

IO, IO, it’s off to storage and IO metrics we go shifting gears a bit from the recent four part series around SSD topics for physical and virtual environment. A while back I did a post about Why VASA is import to have in your VMware CASA along with another piece about Windows boot IO and storage performance impact on VDI planning. Among other things those two pieces have in common is a theme around the importance of storage and IO metrics that matter.
