disk!innovation To help you decide how to discover the the majority of your gadgets you should know what technologies are offered and you will their ramifications. Certain process demonstrated less than is going to be piled during the a beneficial level of ways to maximise results and you can precision, even though at the expense of additional difficulty. 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

drive!technologies!RAID! This will make the complete cabinet from pushes feel like a single higher, prompt SCSI push and requirements zero unique RAID rider. New disadvantage is the fact that SCSI shuttle linking the newest drawer in order to the system will get an effective bottleneck. A serious disadvantage for those who have higher disk facilities is that there is a threshold to just how many SCSI records truth be told there can be get into the latest index. In such cases having fun with SCSI-to-SCSI have a tendency to save yourself entries. Always he or she is set up through the top panel or which have an excellent critical associated with their with the-panel serial software. That brand name of such options try . whose web pages describe multiple expertise. PCI-to-SCSI

SCSI-to-SCSI SCSI-to-SCSI controllers are often used as complete shelves with drives and you can a controller you to links towards computer which have the next SCSI shuttle

computer!development!RAID! This type of controllers require special drivers you also get the fresh means of controlling the RAID configuration along side network hence simplifies management. Already only a few groups of PCI-to-SCSI machine adapters are offered lower than Linux. and SmartCache I/III/IV and you will Silies. These types of controllers are backed by the EATA-DMA driver regarding standard kernel. that also makes reference to individuals standard aspects of RAID and you will SCSI for the addition on the product relevant pointers. Facts from the composer of brand new DPT operator drivers (EATA* drivers) is available from the his profiles to your and you may . and you will . Talking about perhaps not the fastest but have a good track record out-of demonstrated precision. Remember that the maintenance units getting DPT controllers already manage around DOS/Profit simply which means you will need a tiny Dos/Victory partition for the majority of of your own application. And also this form you have got to boot the system into Window to keep your RAID program. featuring as much as 5 independent avenues and very prompt gear situated toward smart controllers. The new Linux driver is actually published by the business alone which ultimately shows it support Linux. Because the ICP-Vortex gives the restoration application having Linux this isn’t needed which have a great reboot to many other os’s towards settings and you can restoration of the RAID system. Which saves you and most recovery time. . vehicle operators appear away from getting Linux. ATARAID

PCI-to-SCSI PCI-to-SCSI controllers is actually, as title suggests, linked to the fast PCI coach which is thus perhaps not enduring the same bottleneck due to the fact SCSI-to-SCSI controllers

computer!innovation!RAID!ATARAID Methods RAID help for ATA pushes are in reality available from lots of people, significantly Promise and you can Highpoint. Speaking of supported within the kernel 2.4 and soon after. For more information investigate to learn more. pages for more information. Software RAID
