AMD RAID Creation

Southbridge Battle: 780a, ICH10 and SB750, Compared
By

The RAIDXpert management console is straightforward. Navigation is on the left, and actions are taken in the center area. It also provides a quick feature overview, illustrated in the screenshot.

First, you have to select the desired RAID level. Keep in mind that you’ll need two drives for RAID 0 or 1, and at least three drives for RAID 5.

 It is possible to use arrays within a RAID array.

We attached six Intel X25-E SSDs to the six SB750 SATA ports, and we selected all of them to be included in our array.

Pick a name to identify the RAID array.

The final settings screen allows the user to select the stripe block size, cache strategy, and other parameters.

Initialization starts right away and took 23 minutes in the case of our our test system. The RAID rebuild, however, only took 20 minutes. It is important to know that the rebuild process does not commence automatically. Once you replace the faulty drive, you have to enter RAIDXpert and trigger the rebuild process. The RAIDXpert tool will tell you that this step is necessary, though.

    Erm, you seem to have made a mistake with either your graphs or your text.

    Looking at the graphs, the LSI's read access time is 250 to 360us = 0.25 to 0.36ms, whereas your text says, 2.5 to 3.6ms (which would be 2500 to 3600us)

    Thanks for an overall good article.

    Anyone reading through the delivery will applaud INTEL's ICH 10R and question the recommendation of the LSI MegaRAID SAS9260-8i.

    I do not question the ability to stick on a battery that protects data inside the card in case of power loss.... no a UPS would protect data.

    Solid State devices are the new kid on the block and not yet MAINSTREAM.
    We also find that the LSI MegaRAID SAS9260-8i is a SATA and SCSI device.

    (In PART) SATA devices have still to catch up with SCSI devices, so if an entity wants a RAID using MAINSTREAM devices the choice goes to LSI.
    I quote..
    " LSI’s MegaRAID SAS9260-8i is one of the first SAS/600 cards, although it’s backward-compatible with Serial ATA at 150 and 300 MB/s via SATA Tunelling Protocol (STP). A different article will deal with SAS/600 soon." Unquote

    One final question: "Should not the SSD have used SAS/600 ?"
