[LiquidWebTravis]

Yesterday Storm On Demand launched Storm SSD, Cloud Servers built on Raid protected Solid State Drives. Storm SSD is built to provide incredible I/O performance. Here are some benchmarks which we performed on Storm SSD, traditional Storm Cloud Servers and Amazon EC2 m1.large.


Complete Test Results:

12GB Storm SSD
4K Sequential Write = 225,000 IOPS
4K Sequential Read = 475,000 IOPS
4K Random Write = 20,000 IOPS
4K Random Read = 35,000 IOPS

Storm 8 GB (non-SSD)
4K Sequential Write = 15,000 IOPS
4K Sequential Read = 28,000 IOPS
4K Random Write = 204 IOPS
4K Random Read = 700 IOPS

Amazon EC2 m1.large
4K Sequential Write = 4,900 IOPS
4K Sequential Read = 7,800 IOPS
4K Random Write = 265 IOPS
4K Random Read = 210 IOPS


Testing performed using iozone3_398 with the following command line options on each server instance:
iozone -l 32 -O -i 0 -i 1 -i 2 -e -+n -r 4K -s 4G

---------------------

Here are iozone stats for transfer rates for the 12GB Storm SSD. Pretty ridiculous.

Sequential Write: 900 MB/s
Sequential Read : 1,875 MB/s
Random Write : 77 MB/s
Random Read : 142 MB/s

Hi there

Is the Bare Metal server with SSD comparable with Storm SSD?

Absolutely, but even better because you are the only customer on that server!

Great.

If i put this quick test in Storm SSD, which number is close to the above data?
dd if=/dev/zero of=/tmp/test bs=64k count=16k conv=fdatasync

Random Write : 77 MB/s
Random Read : 142 MB/s

Sorry I am not good at performing test.
