View the refurbished HP QLogic QMH4062 1GbE iSCSI Adapter for HP c-Class BladeSystem 488074-B21 488081-001 Quickspecs here
The QMH4062 is a dual port fully integrated Gigabit Ethernet iSCSI initiator mezzanine option optimized for iSCSI traffic from an HP BladeSystem c-Class ProLiant server. This iSCSI initiator is an alternative to less integrated Ethernet iSCSI offerings and often more costly non TCP/IP implementations. It is supported on HP ProLiant c-Class servers, all mezzanine slots; multiple adapters per sever.Designed for ultimate performance, the QMH4062 provides offloading of iSCSI and TCP/IP traffic. The QMH4062 supports VMware allowing users the flexibility of ESX 4.0 and ESXi 4.0 host booting from an iSCSI SAN for both Microsoft Windows and Linux. The QMH4062 iSCSI initiator is IPv6 compliant card and can provide a c-Class end-to-end IPv6 solution when using either the Cisco Catalyst Blade Switch 3120 with IPv6 upgrade option or the Ethernet Pass-Thru.
High performance, full software and hardware integrated iSCSI initiator, Dual Gigabit Ethernet ports, Offloading of iSCSI and TCP/IP traffic, Single step iSCSI SAN boot for both Microsoft Windows and Linux, iSCSI boot certified for VMware Server ESX 4.0 and ESXi 4.0, IPv6 compliant providing an end-to-end IPv6 solution when using either the Cisco Catalyst Blade Switch 3120 with IPv6 upgrade option or the Ethernet Pass-Thru, Pre-certified iSCSI targets including the ProLiant Storage Server family, and All-in One (AiO) products, the HP EVA iSCSI Connectivity Option, and many 3rd party storage solutions listed in the iSCSI Target Pre-certification section, Consistent web based and CLI management interfaces across all supported operating systems, IEEE standard support including VLANs, link aggregation, flow control, and QoS, 9kB jumbo frames, Supported on ProLiant c-Class servers, in all mezzanine slots, multiple cards per server, Supported on all HP Ethernet interconnects, including Virtual Connect Ethernet modules.

An aggregate transfer rate of 4,000 Mbps full duplex (2,000 Mbps full duplex per port) delivers outstanding network performance that improves response time and removes bottlenecks across the entire network.
Designed for ultimate performance, the QMH4062 iSCSI initiator provides offloading of iSCSI and TCP/IP traffic. The adapter removes the processing, interrupts, and bus accesses required to support protocols in the host software. The QMH4062 virtually eliminates the host CPU system processing required for iSCSI and TCP/IP, often delivering performance equivalent to direct attached storage (DAS) and Fibre Channel (FC) SANs.
The iSCSI feature boot allows the c-Class ProLiant server to boot from a remote operating system image located on an Ethernet-based storage network. The QMH4062 appears as a SCSI device to an operating system making the remote disk drive appear as a local, bootable C: drive. The server can be configured to connect to and boot from the iSCSI target disk on the network and download the OS image from the iSCSI target disk. To enable iSCSI boot, the adapter must be able to attached to the target LUNs and present those LUNs to the host server during the server's initial power-up. Due to the QMH4062's fully integrated iSCSI implementation, the iSCSI boot initialization can directly boot from a LUN on the storage device in a single step eliminating the need for an additional boot server. In contrast, software-based network adapter iSCSI initiator implementations often require a multi-step process utilizing an additional server to perform the iSCSI boot.
The QMH4062 iSCSI boot is certificated on VMware Server ESX 4.0 and ESXi 4.0. The certification is supported in both a Microsoft Windows and Linux operating system environment.
The QMH4062 is IPv6 compliant, offloading and processing IPv6 packet traffic from the c-Class enclosure when using either a Cisco Catalyst Blade Switch 3120 with the IPv6 software option or the Ethernet Pass-Thru interconnect connected to an IPv6 compliant network. IPv6 is the next generation IP protocol. As compared to IPv4, IPv6 advantages include additional network addressing from 32 bits to 128 bits, increase security, improved management, and more.
iSCSI is a standardized method for transferring blocked-based data across Ethernet. Any iSCSI target adhering to this standard would be compatible. However, to ensure best-in-class operation, the QMH4062 pre-certification program provides extensive SAN interoperability
