EMC’s VNX2 forklift: The importance of hardware re-use, slowing down obsolescence, and maximizing your investment

It was with interest that I watched the launch of EMC’s VNX refresh. The updated boxes got some long-awaited features, EMC talked a lot about how some pretty severe single-threaded bottlenecks were removed, more CPU and memory was put in, and there was much rejoicing.

Not really trying to pick on the new boxes (that will be in a future post, relax :)), but what I thought was interesting was that the code that makes most of the new features a possibility cannot be loaded on current-gen VNX boxes (not even the biggest, the 7500, which has plenty of CPU and RAM juice even compared to the next gen boxes).

Software-defined storage indeed.

What is hard disk short stroking?

This is going to be a short post, to atone for my past sins of overly long posts but mostly because I want to eat dinner.

On storage systems with spinning disks, a favorite method for getting more performance is short-stroking the disk.

It’s a weird term but firmly based on science. Some storage vendors even made a big deal about being able to place data on certain parts of the disk, geometrically speaking.

NetApp delivers 2TB/s performance to giant supercomputer for big data

(Edited: My bad, it was 2TB/s, up from 1.3TB/s, the solution has been getting bigger and upgraded, plus the post talks about the E5400, the newer E5600 is much faster).

What do you do when you need so much I/O performance that no one single storage system can deliver it, no matter how large?

NetApp posts world-record SPEC SFS2008 NFS benchmark result

Just as NetApp dominated the older version of the SPEC SFS97_R1 NFS benchmark back in May of 2006 (and was unsurpassed in that benchmark with 1 million SFS operations per second), the time has come to once again dominate the current version, SPEC SFS2008 NFS.

Recently we have been focusing on benchmarking realistic configurations that people might actually put in their datacenters, instead of lab queens with unusable configs focused on achieving the highest result regardless of cost.
