Server configuration solid hard disk has been a popular choice, especially if only a small proportion of server performance especially there questions. Solid hard disk can help customers to solve the bottleneck of server performance. Solid hard disk can also let the high-speed storage is more close to the processor and will share the storage network this potential bottleneck remove. There are three kinds of solid state hard drive form as a standard: the Sony PCG-GRT390Z laptop cpu fan drive type, SSDDIMM and PCIsSSD.
Hard disk drive type solid hard disk appearance and function similar to the mechanical drive, but no turn needle. This is the first application of common hard disk of the solid state, can be upgraded. Install a SSD drive, through the solid hard disk copy data and to import can easily get speed increase.
Hard disk drive type solid hard disk family at present and new joined the SSDDIMM, as we in the article "SSDDIMM - new options" are discussed, and it can be installed in the server's dual in memory module slot, really very similar to the mechanical drive, can use a standard SAS or SATA medium connected to the system. This type of connection can be ideal boot device. This will be affected by medium connection speed limit, but for many applications for, this is what they need performance improvements.
PCISSD is another server solid hard choice, are rapidly from customers and market recognition. As its name means that, this is a kind of through the PCI bus connection solid state hard disk. So it can be through the high-speed channel directly access the central processor, so able to provide users with very high performance choice. Although most PCI can be guidance, but they are very high to high performance requirements, but SAS/SATA bandwidth are not sufficient to meet the application software performance requirement of the work load is the ideal choice.
PCI solid hard disk can act as a low cost DRAM memory choice. A 1 TB capacity of the solid state hard disk can be used as a memory to replace 100 server configuration of dynamic random access memory, making performance have the greater Toshiba Satellite A665-3DV1 Cpu Fan.
Server configuration choice which paragraph solid hard disk depends on user needs to solve what kind of performance problems and server suitable for installation that solid hard disk. Many PCISSD need volume plenty of PCI slot, most 1 u and 2 u server can meet. In these cases, hard disk drive type solid hard disk or SSDDIMM is a better choice, or even the only choice, it depends on whether there is a hard disk or dual in memory module can be used.
Configuration solid hard disk server can be used for a variety of purposes, also can be used as a Shared storage infrastructure supplement, not substitute, and strengthen. In the next chapter we will focuses on more ideal application cases, including import, cache, space and use solid hard disk to replace dynamic ram memory.
