iSCSI SANs could get a boost from clustered servers.
Increasingly, makers of iSCSI SAN software are porting their products to third-party hardware, specifically Intel-based servers, a move that's making their wares more palatable to data center managers. (See How to Build an iSCSI Disk Array.) Taking the next step to clustered servers only makes sense.
LeftHand Networks, which offers an OEM bundle of its SAN/iQ iSCSI target software with HP's ProLiant DL380, says customers can use Microsoft Cluster Server to scale their iSCSI networks. "It's not just a failover cluster, but a peer-to-peer cluster," boasts LeftHand marketing VP Karl Chen.
Chen has no specific figures for how many customers are deploying SAN/iQ on clustered servers, but he says that the HP bundle accounts for "more than half" the volume of sales on non-LeftHand hardware. Chen also claims that LeftHand has nearly 2,000 customers.
One VAR says LeftHand's solution with HP is selling well. According to Gary Gammon, SVP of marketing for the enterprise division of storage VAR Bell Microproducts, sales of LeftHand's SANiQ plus HP server are exceeding sales of LeftHand arrays alone.
