QLogic, a provider of Fibre Channel host bus adapters (HBAs), is making its 4Gyte SANblade Fibre Channel PCI-X...
2.0 HBA available on HP Integrity and HP 9000 servers.
The HBA products will be available from HP channel partners and directly from HP, and will feature what QLogic claims are a suite of innovative technology advancements that result in what it describes as a “better 4Gbytes”. The HP-branded versions of the HBAs will see use in connecting HP Integrity and HP 9000 servers to high-performance storage in HP-UX 11i operating environments.
Roger Klein, vice-president of marketing at QLogic, says, "The bandwidth provided by QLogic 4Gbyte FC HBAs unleashes the full power of storage applications in these [HP] environments."
The company adds that the new functionality will enable storage administrators in large enterprises to ensure complete business continuity, maintain application performance and cost effectively scale networks.
To ensure the stated better reliability, overlapping protection domains are said to ensure that data is not left unprotected, even for the smallest fraction of time, by generating a new check of parity or ECC before stripping out the old check. To protect data, even if there is a component failure, QLogic is offering Linux drivers that provide customers with automatic failover and fail back between redundant HBAs.
To improve scalability, a Virtual San (VSan) feature, an excusive says QLogic, allows a single HBA to read VSan tags in packets sent from a Cisco MDS switch. As a result, the HBAs support multiple VSans, each with a completely isolated fabric topology and set of fabric services including name server, zone server, domain controller, alias server and login server.
