I had asked if anyone had a Seagate Cheetah 10K.6 (ST3146807LC, 147 GByte) disk running successfully inside an Ultra 60 and/or Ultra 80 system running Solaris 8? Detailed information about the ST3146807LC disk can be found here: http://www.seagate.com/cda/products/discsales/marketing/detail/0,1081,530,00.html Though noone had used this disk yet, everone agreed that it should work. I will buy a disk and give it a try (found it for $617 ;-). Concerns include performance and heat: Performance The internal SCSI bus in the U60/U80 supports 40 MByte/sec, the drive supports up to 320 MByte/sec. Installing a SCSI controller PCI card might be a good idea, if performance becomes an issue. Heat I checked the Sun System Handbook http://sunsolve.sun.com/handbook_pub/ for internal 36.4 GByte 10000RPM Seagate disks supported in the U60, and compared the specs with the ST3146807LC, 147 GByte disk: peak operating current SE mode 5V 12V ST336704LC (36.4 GByte 10000RPM) 0.84 - 1.2 1.12 - 2.64 ST336605LC (36.4 GByte 10000RPM) 0.73 - 1.17 0.82 - 2.35 ST336607LC (36.4 GByte 10000RPM) 0.83 - 1.78 0.68 - 2.21 ST3146807LC (147 GByte 10000RPM) 0.99 - 1.99 0.95 - 2.62 While the peak operating current in SE mode is a bit higher for the ST3146807LC it seems still comparable enough to the 36.4 GByte drives that I am not too concerned about cooling, especially in a datacenter setup with a controlled (cool) environment.
