LeftHand Networks NSM 100

LeftHand Networks (LHN) was a Boulder, Colorado based vendor of iSCSI storage appliances. The company has been bought by Hewlett-Packard. I have an NSM100, their first generation product at home. I don't do much iSCSI, though, so let's see if we can make this a little bit more useful for me.

Hardware description

• 1U rackmount chassis
• 4 hot swap 3.5 inch drive carriers in the front
• Dual 200 Watt power supplies (There is a selector switch at the back of the chassis to choose which power supply is feeding power. It appears a power failure is not handled transparently.)
• A small form-factor WinTel system board with onboard Ethernet
• A PCI slot holding a 1000baseT Ethernet card (the cutout on the back of the case is quite non-standard, though)

Platform limitations

• decade old CPU and motherboard
• Parallel ATA (IDE) hard drives are used.
• Not a lot of RAM inside
• 1 100baseT port for management and a single 1000baseT port for data traffic (some gentle use of a Dremel tool or file should make this better)
