Sun Microsystems: SunFire V20z and StorEdge 3500
Sun represents the higher end of the market with the products that it shipped to the lab this month -- the 1RU SunFire V20z server, fitted with a single and a dual Fibre Channel card, and a 2RU Sun StorEdge 3500 Fibre Channel Disk Array, falling into the DAS/SAN category.
First the StorEdge 3500 array features a lockable front panel covering the 12 3.5in removable hard-disk drive bays. Each bay has a small thumb screw securing the drive bay into place. The disks supplied in the unit were each Seagate/Sun ST373307FC 72GB, 10,000RPM drives giving a total native array of 864GB. Also on the front panel there are drive LED indicators for each disk along with four chassis status LEDs (power, fan, temp, and alert).
If you were beginning to think that the front of the unit was impressive with 12 disks in a 2RU unit, then wait until you hear about the rear. There are two hot-swap redundant 420Watt power supplies, along with two modular interface boards (again for redundancy) -- each provide six ports for Fibre Channel GBICs
The SunFire V20z server is a full-length 1RU chassis. The rear of the unit has a single power supply with an IEC power socket and power switch, a power LED, PS/2 keyboard and mouse ports, an ID and reset button, four gigabit copper Ethernet interfaces, a 15pin VGA port, a single USB port, a 9pin serial port and two expansion slots -- each machine had a FC interface card installed.
The front of the server has two removable HDD bays -- only one of which was populated with a 73GB Ultra 320 SCSI HDD units for the O/S. There are low profile CD ROM and Floppy Disk drives along with four small buttons, power, config and ID and their associated status indicators.
Internally there are two large copper heat sinks over the CPUs cooled by four fans -- two more fans sit near the PSU and two more again near the secondary bank of memory. The cable routing and wiring is very neat. The dual CPU unit has four GB of RAM (2GB per CPU) and expansion room for at least two more modules per CPU. The power supply is 430Watts.
