[Ann Lee]

hi there,

HP DL380R05 5130 (2.0Ghz, 1333 FSB), 4GB RAM, 1x4MB L2 Cache, 72GB SFF SAS
10K 2.5" Hard Drive w/ RAID
or HP ML150TG3 5130 (2.00 GHz, 1333 FSB) HP-SAS,4GB RAM, 1x4MB L2 cache

wondering if freebsd 5.4 can support 2 * dual core 2.0Ghz & 4GB RAM & RAID 1
w/ gmirror? that intel dual-core processor consists of two complete
execution cores in one physical processor and i need to get 2. Serial
Attached SCSI (SAS) hdds w/ raid.

can't install 6.2 because my apps not supported. appreciate if anyone tested
with the above server?
