SSD and SGI Discussion Thread

Unread postby modology » Tue Dec 09, 2008 3:51 am

There is no doubt that SSD is going to replace HDD technology in next decade. With the introduction of 1.6TB SSD SCSI Ultra320 interface, raised the question whether SSD can be used in SGI machines?

With the current economic climate, I don't think people will be replacing things with the regularity they have been doing for the last decade.

If this is an SSD with a U320 interface it should work in any SGI. Assuming proper backwards compatibility, Fuel / Tezro should work either way.

Is there a SCSI to SATA bridge known to work in SGIs? Most (affordable) SSDs have just a normal SATA interface.

P.S. I want to put a nice cheap 128GB MLC SSD -http://www.newegg.com/Product/Product.aspx?Item=N82E16820231221 in my O2.

Perhaps in some apps, unlikely in most....

I'd expect the acard bridges to work just fine (didn't test this myself though). There is even a SCA version designed to take a 2.5" drive, which is what you'd need to fit it internally in an O2.

be aware that there seem to be some quite dramatic random write performance problems with the current "cheap" MLC drives though - the new (and much more expensive) intel MLC drives being the exception: http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3403&p=1

Thanks for the Acard link, I will be getting that... eventually. As far as the write issues, they aren't really issues with the drives, but the controller chipsets. I actually have used 64GB and 128GB ssds (G. Skill and OCZ) at my old job. A number of older SATA I or other SATA chipsets with poor compatibility had concurrent read/ write issues or slow random write issues. More flexible ssd firmwares do help which is one reason why Intel's MLC drives (X-25, X-15) perform so much better. Intel also has a line of SLCs (X-25E) which do even better, but I can't really afford those.
