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.

- 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 and compatibility testing on HP and third-party iSCSI targets, along with multiple software applications.
The QMH4062 has a comprehensive list of pre-certified iSCSI targets including: HP StorageWorks MSA200i product line, HP StorageWorks All-in One (AiO) product line, HP EVA iSCSI Connectivity Option, HP ProLiant Storage Server family and many 3rd party storage including NetApp, EMC, IBM, Dell, Lefthand, LSI, Sun/Storagetek, Promise, Compellent, Quantum, AC&NC, SpectraLogic, StoneFly, iQstor, iStor, DNF, JetStor, Quantum, and Engenio.
- The management of iSCSI solutions based on initiator software can vary widely between the various operating systems. However, the QMH4062 approach provides consistent graphical and command line management interfaces across all supported operating systems simplifying the SAN administrator's tasks.
- The QMH4062 provides the IEEE 802.1Q virtual local area network (VLAN) protocol for Linux. 802.1Q allows each physical port of the QMH4062 to be separated into multiple virtual NICs for added network segmentation and enhanced security and performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to within the same VLAN domain also improves performance. IEEE quality of service (QoS) 802.1p tagging allows the adapter to mark or tag frames with a priority level across a QoS-aware network for improved traffic flow.
- The two ports on the QMH4062 provide port redundancy that can be routed to separate enclosure interconnects for additional availability.
- With multiple dual port adapters supported per server connected to up to two redundant pairs of interconnect modules per enclosure, a very wide variety of high availability I/O configurations are possible.
- Link aggregation allows multiple physical ports to be bonded together to form a single logical ink. This increases the network throughput of a single link and provides redundancy in case of a physical port failure. In case of a port failure, the surviving ports in the logical link (or team) continue to operate. The QMH4062 supports 802.3ad link aggregation within a Linux environment.
