Still waiting for Xiotech..

TechOps Guy: Nate

So I was browsing the SPC-1 pages again to see if there was anything new and lo and behold, Xiotech posted some new numbers.

But once again, they appear too timid to release numbers for their 7000 series, or the 9000 series that came out somewhat recently. Instead they prefer to extrapolate performance from their individual boxes and aggregate the results. That doesn't count of course, performance can be radically different at higher scale.

Why do I mention this? Well nearly a year ago their CEO blogged, in response to one of my posts, and that was one of the first times I made news in The Register (yay! - I really was excited) , and in part the CEO said:

Responding to the Techopsguy blog view that 3PAR's T800 outperforms an Emprise 7000, the Xiotech writer claims that Xiotech has tested "a large Emprise 7000 configuration" on what seems to be the SPC-1 benchmark; "Those results are not published yet, but we can say with certainty that the results are superior to the array mentioned in the blog (3PAR T800) in several terms: $/IOP, IOPS/disk and IOPS/controller node, amongst others."

So here we are almost a year later, and more than one SPC-1 result later, and still no sign of Xiotech's SPC-1 numbers for their higher end units. I'm sorry but I can't help but feel they are hiding something.

If I were them I would put my customers more at ease by publishing said numbers, and be prepared to justify the results if they don't match up to Xiotech's extrapolated numbers from the 5000 series.

Maybe they are worried they might end up like Pillar, who's CEO was pretty happy with their SPC-1 results. Shortly afterwards the 3PAR F400 launched and absolutely destroyed the Pillar numbers from every angle. You can see more info on these results here.

At the end of the day I don't care of course, it just was a thought in my head and gave me something to write about :)

I just noticed that these past two posts puts me over the top as far as the most number of posts I have done in a month since this TechOpsGuys things started. I'm glad I have my friends Dave, Jake and Tycen generating tons of content too, after all this site was their idea!

Xiotech goes SSD

TechOps Guy: Nate

Just thought it was kind of funny timing. Xiotech came to my company a few weeks ago touting their ISE systems, about the raw IOPS they can deliver(apparently they do something special with the SCSI protocol that gets them 25% more IOPS than you can normally get). I asked them about SSD and they knocked it saying it wasn't reliable enough for them(compared to their self healing ISEs).

Well apparently that wasn't the case, because it seems they might be using STEC SSDs in the near future according to The Register. What? No Seagate? As you may or may not be aware Xiotech's unique features come with an extremely tight integration with the disk drives, something they can only achieve by using a single brand, which is Seagate(who helped create the technology and later spun it out into Xiotech). Again, The Register has a great background on Xiotech and their technology.

My own take on their technology is it certainly looks interesting, their Emprise 5000 looks like a great little box as a standalone unit. It scales down extremely well. I'm not as convinced with how well it can scale up with the Emprise 7000 controllers though, they tried to extrapolate SPC-1 numbers from a single ISE 5000 to the same number of drives as a 3PAR T800 which I believe still holds the SPC-1 record at least for spinning disks anyways. Myself I'd like to see them actually test a high end 64-node ISE 7000 system for SPC-1 and show the results.

If your a MS shop you might appreciate Xiotech's ability to integrate with MS Excel, as a linux user myself I did not of course. I prefer something like perl. Funny that they said their first generation products integrated with perl, but their current ones do not at the moment.

This sort of about face with regards to SSD in such a short time frame of reminds me when NetApp put out a press release touting their de-duplication technology as being the best for customers only to come out a week later and say they are trying to buy Data Domain because they have better de-duplication technnology. I mean I would of expected Xiotech to say something along the lines of "we're working on it" or something. Perhaps the STEC news was an unintentional leak, or maybe their regional sales staff here was just not informed or something.
