Hi, Just wonder if there is something special that makes 7120 faster than the server you can assemble by yourself from common components. I have an ultimate task to make a fast zfs :)
And what I'm thinking about is that there is only thing you can't get from nearest server hardware supplier: SDD I see that STEC SSD ZEUSiops are used in 7120. Other staff is pretty common: like 7200 SATA disks, controller probably can't increase speed much since it's a standard SATA 300MB/s Processor and memory are usual, I have for example 2G E5405 quad-core processors and 16Gb RAM and 8 1.5T disks on Adapted 5805. Version is 111b Well, the performance of such system is so-so. 30Mb/s nfs, 50Mb/s iscsi. I'm looking for a way to improve it radically. I have in mind FC, SAS drives and SSD, going to try all of them. I'd like to start with SSD but STEC web-site doesn't show prices. Probably they are too high. Are there any other SSD supplier to try? IBM has 500$ 18G drives www-03.ibm.com/systems/storage/disk/ssd/index.html but probably they don't optimized for writing. IBM says that they can make write rate : 47MB/s and random Read (4K blocks): >5000 IOPS I also see that SUN itself sell 32 GB SATA SSD, 1200$ I see the following info in the catalog: 150Mb/s writing, 5000-7000 random write IOPS and 300 μs max command latency. Is this one going to improve zfs performance?
