The one reservation we have about LeftHand, which is why it didn't make it onto the list sooner, is that its technology is proprietary. That is to say, you can only pool LeftHand boxes into this cluster, which must be managed separately from the rest of your storage. However, this does not appear to be deterring LeftHand's customers, of which there are about a dozen, including MetaSolv Software Inc. (Nasdaq: MSLV), Leopard, and Denver Health.
To move them up the list, though, we will need to see evidence of LeftHand working with partners and interoperating more with other storage technology.
Our latest Bit Bucket casualty is distributed file systems company Acirro Inc., which only launched a few months ago and then promptly laid off half its staff. Never a good sign!
Next up is SANcastle Technologies Inc., makers of a Fibre Channel and Gigabit Ethernet combo switch.
We thought integration of Fibre Channel and Gigabit Ethernet networks over long distances without disruption or technology changes was a rocket of an idea, but it's turned out to more of a small pocket flashlight. Compaq Computer Corp. seems to like the idea, but it hasn't actually committed to an OEM agreement. And who knows what will happen to that, now that it's being folded into Hewlett-Packard Co. (NYSE: HPQ)? (See Compaq OKs SANcastle.)
