IOMeter v2006.07.27 – IOps
We continued our IOMeter testing with some (simulated) real world action – our standard PCPer quad of IOMeter profiles:
In our standard PCPer IOMeter testing, we see a very close race between the ioDrive and DDRdrive. The extremely low latency enables the DDRdrive to reach top speed at very low queue depths. The ioDrive is able to brute force its way past with greater bus bandwidth, but requires higher queue depths to accomplish the task. The X25-M did manage to take a jab at the big boys, but only in the web server test, and only at higher queue depths. We will be adding X25-E figures to the mix as soon as we get one in the lab. The poor VelociRaptor remained plastered to the floor throughout all testing.
Note: For those thinking an I-RAM comes anywhere close to these numbers, I invite you to view this page for comparison.
specs aren’t much better than
specs aren’t much better than a gigabyte i-ram except this device currently costs almost $2000, the i-ram cost $150 at release and currently ranges from $100-$150.
i-ram doesn’t get near the same iops but it has the same storage capacity. and gets 130mbs read/write so price wise i-ram is alittle more realisitc.
hardware ramdrives could be huge if companies actually put some effort into making an affordable current device. They always make it too soon or too late, and not very well.
better off buying a nand flash ssd for $99 and just replacing it every few years. Will be cheaper and faster in read/write/iops.
This isn’t a competitor for
This isn’t a competitor for SSD or the iRam. It’s a non-volatile ramdisk and has a very specialised use.
This device runs squarely up against STEC’s 8Gb ZeusRAM devices – and eats them for lunch because it’s not tied to a SATA/SAS bus AND because it’s about 1/3 the price.
As for usage: This is an ideal device for ZFS ZIL – only a few GB is needed and the faster you can commit it to the ZIL, the faster a server can signal “ready” back to the client on write requests.
As TFA said, this device is intended for Enterprise usage. I’d extend that and say anywhere a high end NAS is required, this is a good fit within that NAS.
I’d prefer to see PCIe x4 though, however it’s probably fast enough for the purposes at hand. 🙂
Is there a similar product
Is there a similar product for Notebooks?
Many yrs ago I saw an adapter for 2 SO-Dimm memory sticks that one could int one of the slots in a Notebook, where can I find these? (One could expand the memory, one would get 4 slots instead of the original 2.)
