This IOPS distribution is very interesting.
I’m playing with a RAID array of 5x Intel X-25E drives.
It turns out they need a lot of tuning. I’ll blog about this later.
What is more interesting is this distribution of IOPS across threads.
This is using sysbench and the seqrd file IO test.
My hypothesis is [...]
What do you get when you take 7 Intel SSDs and throw them in a desktop? 1M IOPS:
“So as we look at optimizing some of those things,” he said, “like interrupts, driver speculation, improving the physical interface between SSDs, and the system, we expect great gains in power, performance, and cost.”
Gains in performance, for [...]
Mark Callaghan made some progress with 4k pages in and InnoDB. I ran some number on SSD with 8k pages but my 4k build would dump core.
The numbers for 8k show some potential.
The way I see this working is that one would buffer the first and second level btree pages in memory and the [...]
Has anyone done any more work on recompiling InnoDB with 4k pages and benchmarking under SSD?
We’re building out a new DB that uses very small records (around 32-64 bytes) so reading a whole 16k for this record should have a performance difference.
I haven’t seen any benchmarks on 16k random read IOPS on the Intel [...]
We’re looking to hire a Senior MySQL DBA over at Spinn3r.
You should obviously have MySQL experience. Love SQL, hate data corruption and slow queries, and preferably live in San Francisco.
Linux experience would be nice as well but not required.
Extra points if you are excited about SSD, *huge* amounts of data, [...]
Here’s the problem I currently have.
We’re looking at deploying the Intel X-25M MLC SSD in production.
The problem being that this drive has a lower number of erase cycles but is much cheaper. Than the Intel X-25E SLC drive.
However, in our situation we’re write once, read many. I’m 99% certain that we will [...]
OCZ has their new PCI flash devices on the market at $3.36 per GB … these guys are FAST.
Read: Up to 500 MB/s-Write: Up to 470MB/s -Sustained Write: Up to 200MB/s
…
They still aren’t commodity just yet but flash on PCI is very interesting.
Another major issue here is the device driver.
If OCZ were [...]
About two weeks ago we completed a pretty big project to migrate Spinn3r’s operations from ServerBeach over to Softlayer.
The entire project, from start to finish, too just over one month.
I’m also proud to note that not a single customer noticed any downtime or any issue with our migration. It cost [...]
I think Amazon just fired a major show across the bow of dedicated hosting companies like ServerBeach and ServePath with their new reserved instance pricing.
I just ran the pricing numbers again and Amazon EC2 is almost the same as we’re currently paying if we pay up front for the year. Of course we’d require [...]
Not literally, but you can hear the sounds of some dead and dying hard drives here…
I hope to have SSD replace all the HDDs in our cluster so that we never have to hear these sounds again.
The Sun Fishworks guys were nice enough to invite me for a demo of their new 7000 series storage device.
We bang the heck out of our IO systems here at Spinn3r so having more options is always welcome.
Bryan Cantrill, one of the original DTrace developers, worked on this bad boy so there’s obviously going to [...]
Apparently, Linus has a new Intel drive he’s happy with:
In contrast, the Intel SSD does about 8,500 4kB random writes per second. Yeah, that’s over eight thousand IOps on random write accesses with a relevant block size, rather than some silly and unrealistic contiguous write test. That’s what I call solid-state media.
They are almost certainly [...]
Spinn3r is hiring for an experienced Senior Systems Administrator with solid Linux and MySQL skills and a passion for building scalable and high performance infrastructure.
About Spinn3r:
Spinn3r is a licensed weblog crawler used by search engines, weblog analytic companies, and generally anyone who needs access to high quality weblog data.
We crawl the entire blogosphere [...]
This press release on Mtron’s sites is interesting:
In the second half of 2008, Intel will release both high-performance SSDs for use in servers and storage, and exclusive SSD models for consumer electronics; the industry is thus watching whether Google will introduce SSD systems.
Google reportedly will be supplied with Intel’s SSD-embedded storage devices at the end [...]
More competition for Mtron is right around the corner.
The Mtron PRO 7000 at 32GB is $1,129 or $35 per GB and can write at 90MB/s.
The Super Talent MasterDrive DX at 64GB is $1299 or $20 per GB and can do 70MB/s throughput.
So the Super Talent drive is about 22% slower but 42% cheaper.
Though [...]
We’ve had our SSDs in production for more than 72 hours now. We’ve had them in a slave role for nearly a week but they’ve now replaced existing hardware including the master.
The drives are FAST. In our production roles they’re reading at about 45MB/s and writing to disk at about 15MB/s and using [...]
It dawned on me today that there are now three independent branches of InnoDB development. Some might call them forks but it appears they are all friendly forks.
Hopefully they will merge at some point.
From what I see we have:
1. The official MySQL sources.
2. The InnoDB 5.1 plugin
3. The Google patches that [...]
Seagate sues STEC (an SSD vendor):
Seagate was talking a big game last month about how SSD makers like Samsung and Intel were infringing its patents, and the company wasn’t joking around, following up all that tough talk with… what appears to be a test case against relatively minor vendor STEC. Seagate says STEC’s drives violate [...]
When I started looking at SSDs I compared the various Mtron models and they have a 32GB drive (vs 64GB) that prices out at $15/GB.
That’s a sweet spot so I decided to go with that model.
Well now it looks like that specific model is being discontinued in favor of the higher end mode [...]
This seems interesting:
Flash memory has become the most important storage media in mobile devices, and is beginning to replace hard disks in desktop systems. However, its relatively poor random write performance may cause problems in the desktop environment, which has much more complicated requirements than mobile devices. While a RAM buffer has been quite successful [...]
