Note

If you wish to make a RAID 0+1 array using 4, 6, or 8 drives you need to choose RAID 1 (mirroring) and then follow the steps below to create the array.

9.Press SEL to assign Stripe Block Size. 64KB is the optimum value for most applications. Choosing the proper Stripe Block Size facilitates efficient data flow. You might want to choose a different value if you know the size of the cache buffer in your hard drives or the average data block size of the data you retrieve. See Choosing Stripe Block Size on page 10 for more information.

10.Press button to choose the GB Boundary feature. Press SEL to toggle between GB Boundary ON and GB Boundary OFF. The size of the array is always restricted by the size of the lowest capacity disk drive. GB Boundary ON (recommended) causes the size of the array to be rounded down to the nearest whole gigabyte. GB Boundary OFF does not round off the size of the array. (For example: Enabled—1.6GB = 1GB; Disabled—1.6GB = 1.6GB.) See Gigabyte Boundary below for more information.

Note

The Gigabyte Boundary feature is only available for RAID levels 1, 0+1, 3, and 5.

11.Press button to choose the Add/Remove Drives feature then press SEL.

12.Use the and button to select each drive. Press SEL to toggle between adding or removing a drive. Press EXIT when done.

13.Press SEL to Save Changes

14.Press SEL to create the array or press EXIT to cancel.

15.If you pressed SEL to create the array then you should see the message “Array has been created.”

16.Switch the UltraTrak100 power off – wait 5 seconds and switch the power back on.

You have successfully created an array manually. If haven’t already done so, you need to select a SCSI ID before you can begin using the UltraTrak100.

GIGABYTE BOUNDARY

The Gigabyte Boundary feature is designed for fault tolerant arrays (RAID 1, 0+1, 3 and 5) in which a drive has failed and the user cannot replace the drive with the same capacity or larger. Instead, the Gigabyte Boundary feature permits the installation of a replacement drive that is slightly smaller (within 1 gigabyte) than the remaining working drive (for example, a 20.5 GB drive would be rounded down to 20 GB). This can be helpful in the event that a drive fails and an exact replacement model is no longer available. Without this feature enabled, UltraTrak100 will NOT permit the use of a replacement drive that is slightly smaller than the remaining working drive.
