Most Versatile Dual AMD Opteron 4300/4200/4100 Serverboard The ASUS KCMA-D8 server motherboard is a feature-rich yet affordable choice for customers, based on cost effective dual AMD Opteron 4300/4200/4100 series processors, featuring an AMD SR5670/SP5100 chipset, dual-channel DDR3 per processor, high power efficiency, ASUS′ unique PIKE SAS2 upgrade kit, & ASMB4-i KVM module for remote management, making it an ideal foundation for versatile AMD C32 solution. With all above amazing features, ASUS engineer integrates into an ATX form factor. Most Versatile Dual AMD Opteron 4300/4200/4100 Serverboard How to identify MB supporting Opteron 4300/4200 CPU 12" x 10" ATX Form Factor & 24+8 pin power connector The ASUS KCMA-D8 serverboard allows users to build a cost-effective & competitive server with wider choice. The serverboard follows standard ATX mounting-hole locations, so users can choose desktop PC ATX chassis which is cost-effective & easily available from market or server chassis which rack & tower chassis can be fitted in cabinet for enterprise usage. Furthermore, the 24+8 pin power connector supports both ATX (for desktop PC use) & SSI (for server use) power supply, with the former reducing total cost, & the latter offering advanced server features. High Power Efficiency with 85%+ Vcore efficiency The KCMA-D8 delivers 85%+ power efficiency, while CPU is under 30%~90% working load. It can reach up to maximum 88% of the power efficiency & then save power bill for users. Hence, the longer you use KCMA-D8, the more expenses you can save. Besides, the solid & long life conductive polymer capacitors (sustaining 5, 000 hrs @ 105?) in the serverboard ensure longer component life & lower power consumption ? creating higher energy efficiency. Support Up-To-Date Opteron 4300/4200/4100 Processor KCMA-D8 is based on the latest AMD C32 platform to support 8/6/4 core AMD Opteron™ 4300/4200/4100 series processors, which have outstanding performance-per-watt, saving up to 22% power consumption compared to previous AMD Opteron 2400 series processor (Information is from www.amd.com); while its dual HT3 links (between CPUs) with up to 6.4GT/S interconnect rate per link, 6 MB shared L3 cache, & 8 DDR3 memory delivers better bandwidth performance. The platform is designed for power efficient & cost efficient 2-way server solutions. Built in Linux RAID 5 solution For better data protection, the KCMA-D8 has built in Promise ROMB (RAID on Motherboard) to support RAID 0, 1, 10 & RAID5 in both Windows & Linux operating system. The complete, fast & efficient RAID Solution benefit enterprise customers in maximizing SATA storage system performance. ASUS PIKE SAS2 6G Storage Supported ASUS optional PIKE provides slim-sized & flexible storage options. SAS RAID upgrades can be achieved directly via a unique slot?without sacrificing expansion capability. Also, KCMA-D8 supports the latest SAS2 6 Gb/s storage through PIKE interface, doubling transmission speed of SAS 3 Gb/s. ASUS PIKE 2008 supports RAID 0, 1, 10 & 1E; PIKE 2008/IMR supports RAID 0, 1, 10, 5 & 50; PIKE 2108 is a hardware RAID solution, which can support high performance RAID 0, 1, 10, 5, 6, 50 & 60. Built in BMC engine, IPMI 2.0 + KVM-over-IP enabled by ASMB4 Module The optional ASMB4-i KVM provides remotely real-time & full control via accessing to the system based on BIOS-level keyboard, video monitor, & mouse (KVM over Ethernet) from any local computer anywhere, anytime.
