Musings on storage, tuning, backups and more – delivered with a no-nonsense approach. By Dimitris Krekoukias
This is going to be a mercifully short entry. I’m saving the big one for another day 🙂
One of the features of NetApp storage is that by using Converged Network Adapters (CNAs) one can use a single wire and transport over that FC, iSCSI, NFS and CIFS, at the same time.
Following the new NetApp block-based SPC-1 results yesterday, here is some NAS benchmark action. This page contains all the SPEC SFS results. SPEC SFS is the NAS equivalent of SPC-1.
SPEC SFS is more cache-friendly than the brutal SPC-1, click here for some more information regarding this industry-standard NAS benchmark. The idea is that thousands of CIFS and NFS servers have been profiled and the benchmark reflects real-life NAS usage patterns.

The SPC-1(E) benchmark is the standard high-intensity test for block storage, consisting of very stringent rules and a standard test suite.
SPC-1 is one of the worst things you can do to a disk array. The benchmark itself does a lot of writes (about 60%), is highly random and is hostile to most caching systems. Which neatly explains why IBM has all kinds of system submissions but doesn’t show XIV, and the complete absence of another prominent vendor (look at the submissions, you’ll figure it out – the big boys of storage are NetApp, IBM, HDS, HP and one more 🙂 ).
NetApp has been selling our custom cache boards with flash chips for a while now. We have sold over 3PB of usable cache this way.
The question was raised in public forums such as Twitter – someone mentioned that this figure may be more usable Solid State storage than all other enterprise disk vendors have sold combined (whether it’s used for caching or normal storage – I know we have greatly outsold anyone else that does it for caching alone 🙂 ).

[Update: some grammar mistakes fixed and a few questions added]
Before anyone starts frothing at the mouth, notice that in the categories this post is part of FUD 🙂 Always do your own analysis… I just wanted to give people some food for thought, like I did when FASTv1 came out. I didn’t make this up, it’s all based on various EMC documents available online. I advise people looking at this technology to ask for extensive documentation regarding best practices before taking the leap.
