A RAID5 scheme for upgrading common Tower server storage

At present, if the server on the market from the internal can provide the hard disk slot, the tower server undoubtedly has an absolute advantage, because the tower server provides a larger internal space.

and 1U of rack server generally can only provide 3 hard disk bits, 2U rack server can only provide 6 hard disk bits, if the use of 3U rack-like server, the server itself price is very high, this does not meet the current http://www.aliyun.com/ Zixun/aggregation/9348.html "> The actual situation of small business. and the tower server not only can provide more hard disk bit, and low price. Therefore, the tower server has a great advantage in data storage.

When discussing data storage within a server, one problem we cannot ignore is the security of the data store. The security of the data store is usually determined by the raid level, and the more RAID levels are supported, the higher the security of the data store. Most servers in the market today only provide support for RAID 0,1,10 in their original state, and it is clear that such RAID levels are only suitable for use by individual users, and if you want to protect the data in your enterprise, the RAID level should at least support RAID 5 to protect enterprise data security. As a result, array cards that support RAID 5 are widely used in servers.

In general, the data store within the server has to consider not only capacity issues but also security issues, and most of the existing servers do not provide support for RAID 5, so when buying a server, we generally need to increase RAID cards to support RAID 5 and secure data storage. The array card is not only to provide data storage security, but also to expand the number of mounted hard disk, so, after the enterprise purchase the array card will also add some hard disk to meet the needs of data storage.

Through the above description, I believe you have the server support RAID 5 have their own insights, in order to facilitate the user to further understand that we have the server +raid card + 3 hard disk mode, and price positioning in small enterprises can accept the 30,000 yuan, for everyone to build two sets of support raid 5 Server System.

Common Tower Server (AMD processor) + Adaptec 2230SLP + Seagate st3146807lc 

Ordinary tower server can be a core using AMD Processor Tower server, standard one AMD Operton 244 processor, dual processor architecture, standard 1G DDR memory, maximum memory can be expanded to 12GB via the 6 DIMM slots provided on the motherboard. Through the motherboard integrated ATA100 hard disk controller, you can connect the IDE hard disk andStandard 1 120GB 7200 RPM IDE hard drive. General tower server motherboards typically have 3 64-bit 100MHZ PCI slots and 2 32-bit 33MHz PCI slots, providing 4 IDE interfaces, 1 floppy drives, 1 ports, 2 serial, 4 USB, 2 gigabit NICs.

This server uses high precision temperature control unit in management, intelligent IC and high sensitive sensor, can detect the hardware running in the server, and can set up and manage the system, and can diagnose the hardware of the fault.

Adaptec SCSI raid 2230slp 

Adaptec SCSI raid 2230SLP is a high-performance SCSI RAID card introduced by Nasdaq, which uses MD2 small size design , not only for use with tower servers, but also for rack-type server use. It uses the High-performance raid on Chip (ROC) ASIC chip as its core, paired with 128MB DDR cache, to support up to 30 hard drives. The RAID card integrates dual-channel Ultra SCSI 320 controllers, supports a 64-bit 133MHZ PCI bus, supports RAID 0,1,5,10,50,jbod levels, and provides good security for data storage.

This RAID card uses Adaptec's unique disk utilization optimization technology, which greatly increases the utilization of the connected hard disk space, which enables remote administration through Adaptec Storage Manager software and eases the burden on administrators. And the RAID card supports online capacity expansion, supports background initialization, supports S.M.A.R.T. and saf-te, supports hard disk thermal backup, supports hard drive hot plug, supports bootable array and many other functions.

Seagate st3146807lc 

Seagate ST3146807LC is a high-performance SCSI hard drive with a SCSI hard drive capacity of 146GB, 10000 rpm, Ultra SCSI 320 interface technology, With 8MB cache, the average seek time between 4.7ms to 5.2ms, continuous data transmission rate between 38mb/s to 68.5MB/S, is the ideal server hard disk choice.
