LSI SAS3442X-R SAS/SATA HBA Card and an external enclosure.
807731Jan 6 2007 — edited Feb 8 2007There are many Sun Systems that only have two drive bays, so expanding internally really isn't an option. However, if you are willing to think outside the box, you have more options.
I found a SAS/SATA card by LSI that supports Solaris SPARC. It has internal and external connectors. It is not cheap. The cheapest I have found was about 212. I believe it is the 8-port version (SAS1068) of the adapter that is built in to the T2000. (SAS1064)
Right now, I am thinking about getting that card and an external SATA enclosure which will hold around 4 drives. SATA drives are relatively cheap, so a workable solution would be to get a pair and mirror them.
BTW, I am a probably upgrading to a Sun Blade 2000. It would be kind of pointless to spend more on storage than a Blade 100 is worth.
