BIOS/CMOS

2008年4月15日 没有评论

BIOS is shorter of Basic Input/Output System, which is stored in ROM/EEPROM/EPROM/Flash. It is a coded program, and uses a dedicated memory called CMOS to keep its implements and setting, for example, date, harddisk driver and so on. It’s a fucking life, while everyone has to live. It’s hard life.

Intel 5400: Harpetown

Intel 5200: Wolfdale-DP

New Super servers and workstations based on the Intel 5100 chipset, with regular DDR2 memory instead of FBD memory, offer superior performance-per-watt and cost-to-performance ratios, because DDR2 memory costs about $10 less per module compared to FBD and generate less heat.

Designed for cost-effective 1U/2U/4U and tower systems, the new X7DCL-i server board supports up to 32GB of DDR2 memory, six expansion slots including three high-performance PCI-Express slots, and six SATA2 ports with RAID5 in a standard ATX form factor. For onboard SAS support, SuperMicro also offer the X7DCL-3, which supports SuperMicro also offer the X7DCL-3, which supports eight SAS ports with RAID5 optional.

VMDq: Virtual Machine Device Queues is another breakthrough technology from Intel that helps offload network I/O data, processing from the VM monitor software to network silicon.

Receiving Packets: As data packets arrive at the network adapter, a layer 2 classifier/sorter in the network control sorts and determines which VM each packet is destined for based on MAC addresses and VLAN tags, then places the packet in a receive queue assigned to that VM. The hypervisor’s switch merely routes the packets to the respective VM instead of performing the heavy lifting work of sort data, Thus, VMDq, improves platform efficient for handle receives side network I/O and increase CPU utilization for application processing.

EIDE: Enhanced IDE, the latest ATA version is 8, which is also in processing.

48bit address, equals 144 PeraBytes.

1068E chipset and its drivers

2008年4月14日 没有评论

LSI 1068E chipset, by setting a jumper, can be used in 2 modes.

1. 1068MPT-Fusion, PCI ID 1000:0054, Embedded MPT-Fusion BIOS, used with MPT-Fusion(SAS) driver.

2. 1068MegaRAID, PCI ID: 1000:0055, Embedded MegaRAID BIOS, providing RAID 0,1

LSI MegaRAID 84016 SAS controller contains two 1068E controllers and one Intel ICP unit. It driver is megaraid_sas.ko, not mpt_sas.ko as 1068E D.Card in BX1200 platform, which just acts as HBA card.
