computer!tech In order to determine how to discover the a lot of your own products you have to know just what technologies are readily available and you can its effects. Certain processes discussed below are going to be stacked within the a great amount of an approach to increase performance and accuracy, even though at the cost of added complexity. RAID

disk!technologies!RAID This is a method of increasing reliability, speed or both by using multiple disks in parallel thereby decreasing access time and increasing transfer speed. A checksum or mirroring system can be used to increase reliability. Large servers can take advantage of such a setup but it might be overkill for a single user system unless you already have a large number of disks available. See other documents and FAQs for more information. For Linux one can set up a RAID system using either software (the md module in the kernel), a Linux compatible controller card (PCI-to-SCSI) or a SCSI-to-SCSI controller. Check the documentation for what controllers can be used. A hardware solution is usually faster, and perhaps also safer, but comes at a significant cost. A summary of available hardware RAID solutions for Linux is available at . SCSI-to-SCSI

disk!technologies!RAID! This makes the complete cupboard regarding drives look like an individual high, punctual SCSI drive and needs zero unique RAID rider. The downside is the fact that the SCSI coach linking brand new pantry to the machine becomes a beneficial bottleneck. A significant drawback for those who have high computer farms is that there clearly was a limit to help you exactly how many SCSI records truth be told there can also be be in the fresh new directory. In these instances using SCSI-to-SCSI will rescue entries. Constantly he’s designed via the side committee or with a good terminal connected to the for the-board serial interface. You to manufacturer of such systems try . whose sites identify numerous assistance. PCI-to-SCSI

SCSI-to-SCSI SCSI-to-SCSI controllers are usually then followed since complete shelves with pushes and you will an operator one to connects towards computers with another SCSI shuttle

disk!technologies!RAID! This type of controllers wanted unique motorists nevertheless will also get the form regarding managing the RAID arrangement across the system and this simplifies management. Already only a few groups of PCI-to-SCSI servers adapters is served not as much as Linux. along with SmartCache I/III/IV and you can Silies. These types of controllers are supported by brand new EATA-DMA rider in the important kernel. which also describes individuals general areas of RAID and SCSI within the inclusion toward equipment relevant pointers. Much more information on author of brand new DPT controller people (EATA* drivers) can be obtained at their profiles on the and you can . and you may . Talking about not the fastest but i have an excellent history away from confirmed accuracy. Observe that the maintenance gadgets to possess DPT controllers already focus on under DOS/Earn merely and that means you will demand a tiny 2/Winnings partition for many of your own application. This means you have to footwear the computer towards the Windows to keep up the RAID program. presenting as much as 5 independent channels and incredibly fast technology centered for the wise controllers. The latest Linux rider was compiled by the company alone which will show it help Linux. Given that ICP-Vortex offers the repairs app having Linux this isn’t expected having a great reboot to other systems to the configurations and you may maintenance of the RAID program. It helps you save including additional downtime. . drivers arrive out-of to have Linux. ATARAID

PCI-to-SCSI PCI-to-SCSI controllers was, while the identity indicates, linked to the high-speed PCI bus in fact it is hence not struggling with a comparable bottleneck since the SCSI-to-SCSI controllers

computer!innovation!RAID!ATARAID Methods RAID service to have ATA drives are in reality available from loads of people, significantly Vow and Highpoint. These are supported in kernel dos.4 and soon after. To learn more read the for more information. users for more information. App RAID
