disk!innovation To decide how to get the much of your own products you must know what technology is readily available and you can the ramifications. A few the league hesap silme of the techniques revealed below might be piled during the an excellent level of ways to maximise overall performance and you may reliability, in the event at the expense of extra 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!technology!RAID! This will make the whole cabinet out of drives look like just one higher, quick SCSI push and requirements no special RAID rider. Brand new disadvantage is the fact that SCSI shuttle linking the brand new closet to the system will get a great bottleneck. A critical drawback if you have higher computer farms is that there clearly was a limit to just how many SCSI records truth be told there can be get into the latest index. In these cases using SCSI-to-SCSI usually conserve entries. Usually they are set up via the front side committee or that have a beneficial terminal linked to the into-board serial screen. You to name brand of such possibilities is actually . whoever web pages define several expertise. PCI-to-SCSI

SCSI-to-SCSI SCSI-to-SCSI controllers are often adopted due to the fact over cabinets which have pushes and you can a control you to links with the desktop that have a second SCSI shuttle

drive!tech!RAID! These types of controllers require unique vehicle operators nevertheless will also get the form from managing the RAID arrangement over the community hence simplifies administration. Already not all the families of PCI-to-SCSI host adapters is actually supported significantly less than Linux. in addition to SmartCache We/III/IV and Silies. This type of controllers is supported by the latest EATA-DMA rider regarding the standard kernel. which also identifies various standard aspects of RAID and you will SCSI for the inclusion to the tool related pointers. Considerably more details in the writer of brand new DPT control motorists (EATA* drivers) is obtainable at the his users toward and you may . and you can . Speaking of maybe not the quickest but have a great track record out of confirmed accuracy. Remember that the maintenance equipment for DPT controllers already work on below DOS/Winnings merely you will demand a little Dos/Profit partition for many of your app. This also setting you have to boot the device with the Windows to steadfastly keep up the RAID program. presenting to 5 separate streams and very punctual hardware depending to your intelligent controllers. The brand new Linux driver are published by the firm in itself which shows they assistance Linux. Just like the ICP-Vortex provides the fix application getting Linux this is not necessary having a good reboot for other os’s into the setup and you will restoration of RAID system. That it helps you to save also a lot more downtime. . drivers appear out of to have Linux. ATARAID

PCI-to-SCSI PCI-to-SCSI controllers was, just like the term implies, connected to the high speed PCI bus in fact it is for this reason perhaps not struggling with an equivalent bottleneck while the SCSI-to-SCSI controllers

drive!innovation!RAID!ATARAID Knowledge RAID help to own ATA pushes are now offered by a lot of people, somewhat Guarantee and you may Highpoint. These are supported inside kernel 2.cuatro and soon after. To learn more take a look at the for more information. pages to learn more. Application RAID
