Sun Ultra[tm] 25, RoHS:Y Workstation: Hardware Specifications

Processor
Number One
The processor communicates with the system I/O through the 167MHz Jbus interface.
Architecture 1.34GHz UltraSPARC IIIi:
Cache memory 1MB Level 2
Main Memory
Capacities Characteristics of the DDR-1 ECC-protected memory include:
  • Maximum system memory - 8GB (using 2GB DIMMS)
  • Maximum DIMMS - 4 (8GB max)
  • Maximum DIMM slots - 4
  • Two physical banks of two DIMMs
  • DIMM sizes offered - 512MB, 1GB, or 2GB
  • DDR-1 registered ECC memory at 266 MHz
  • Processor accesses memory across the 128-bit data bus. Must be installed in pairs.
Standard Interfaces
Audio Four AC97 ports as follows:
  • Two in front
  • Two in rear
Ethernet Two 10/100/1000 BaseT (Gigabit) ethernet ports (rear of workstation)
Expansion Slots Five slots as follows:
  • Two PCI-Express: both mechanical (x16) and electrically (x8)
  • One PCI-Express mechanical (x8) and electrically (x4)
  • Two PCI-X 100MHz/64 bit slots
Serial Two ports (rear of workstation)
USB Six ports as follows:
  • Two USB 2.0 ports in front
  • Four USB 2.0 ports in rear
Internal Storage
Disks Allows a maximum of four internal 3.5" SAS (146GB - 15000 RPM) or SATA (80GB or 250GB - 7200 RPM) disk drives. Drives are supported by an integrated PCI-X SAS/SATA disk controller.
Optical Disk Drives Optical disk drive as follows:
  • One 8x DVD-RW/24x CD-RW (Slot-loading)
  • ATAPI - Interface
Note: Systems that ship without an optical disk drive require an optical disk drive EMI filler panel in the unoccupied bay to cover the slot opening.
Graphics
Cards Note: Solaris 10 currently does not support dual graphics cards, each driving a monitor.
