 High-speed on-chip reduced instruction set computer (RISC) processor (see
“ASIC with Embedded RISC Processor” on page 6)
 Integrated 96KB frame buffer memory
 Quality of service (QoS)
 Serial gigabit media independent interface (SGMII), gigabit media
independent interface (GMII), and media independent interface (MII)
management interface
 256 unique MAC unicast addresses
 Support for multicast addresses through a 128-bit hashing hardware
function
 Support for VMDirectPath I/O over PCI physical functions
Marvell 57xx and 57xxx Series Adapters support VMDirectPath I/O in Linux
and ESX environments. VMDirectPath I/O is not supported in Windows
environments. Marvell 57xx and 57xxx Series Adapters can be assigned to
virtual machines for PCI pass-through operation. However, due to function
level dependencies, all PCIe functions associated with an adapter must be
assigned to the same virtual machine. Sharing PCIe physical functions
across the hypervisor and/or one or more virtual machines is not supported.
 Serial Flash NVRAM memory
 JTAG support
 PCI Power Management Interface (v1.1)
 64-bit base address register (BAR) support
 EM64T processor support
 iSCSI and FCoE boot support
 Virtualization:
 Microsoft
 VMware
 Linux
 XenServer

 Single root I/O virtualization (SR-IOV)
iSCSI
The Internet Engineering Task Force (IETF) has standardized iSCSI. SCSI is a
popular protocol that enables systems to communicate with storage devices,
using block-level transfer (that is, address data stored on a storage device that is
not a whole file). iSCSI maps the SCSI request/response application protocols
and its standardized command set over TCP/IP networks.
