With all that Microsoft Corp. (Nasdaq: MSFT) influence, DeNardo thought an iSCSI system was a good idea, and he liked what he'd heard about LeftHand. Siemens thought he was crazy.
They were negative on LeftHand stuff, DeNardo says. They said it was too new. But we couldnt afford EMC or HP. [Those vendors] wanted us to use DAS for databases and NAS for file storage. We didnt want to put databases and file servers on different systems. We wanted one system.
DeNardo dismissed Siemens and installed LeftHand. My message is: Dont listen to the big boys, theyre used to doing things one way.
DeNardo says he got the SAN set up in less than a day. His system has 5 TBytes of primary storage in the main county site in Eagle and 5 TBytes in a disaster recovery site seven miles away in Gypsum. The SAN uses Cisco Systems Inc. (Nasdaq: CSCO) switches.
Another big piece of the disaster recovery process is PowerQuest Inc. V2i Protector software. V2i takes snapshots of the servers and stores them on the SAN. Data is replicated from the remote sites to the main facility, and from there to the DR site. For another line of defense, the county uses a Qualstar Corp. (Nasdaq: QBAK) 9-TByte tape library.
