MicroNet Technology RAIDBank4 manual To service interruptions

host bus adapter and the host Operating System to be usable. Windows 2003, Vista, Windows 2008, Mac OS X >10.4.8, and Linux distributions with appropriate kernels all support large LUNS. Windows XP and prior cannot address large LUNS natively over USB, and must use eSATA host bus adapters that have RAID support to be usable. MicroNet offers such host bus adapters- consult your MicroNet authorized reseller for more information.

3.1.4The volume set attributes screen shows the volume set default configuration value that is currently being configured. The volume set attributes are:

Volume Name	Default name is RAIDbank-VOL#nn. You can rename the volume set
	name providing it does not exceed 15 characters.
RAID Level	RAID level 0,1, 0+1 (10), 3 and 5.
Stripe Size	This parameter sets the size of the segment written to each disk in a
	RAID 0, 1, 3, or 5 logical drive. You can set the stripe size to 4 KB,
	8 KB, 16 KB, 32 KB, 64 KB, or 128 KB. A larger stripe size produces
	better-read performance for mostly sequential reads. For better
	random reads performance, select a smaller stripe size.
Write Cache Mode	RAIDBank4 supports Write-Through and Write-Back Caching algo-
	rithms. In the Write-Back caching method, modifications to data in
	the cache aren’t copied to the cache source until absolutely neces-
	sary, whereas Write-Through cache data is written to the storage and
	the cache memory simultaneously. Write-back caching yields better
	performance than write-through caching because it reduces the num-
	ber of write operations to disk, but is also more prone to data loss due
	to service interruptions.
HOST Channel (SATA/USB)	RAIDBank4 supports two host channels. Host Channel 0 is the host
	eSATA interface, and Channel 1 is the USB 2.0 host interface.
Drive Number (LUN 0-4)	RAIDBank4 supports 4 logical units. Any Volume Set may be mapped
	to eSATA and/or USB host channels independently.
Host SATA Transfer Mode.	SATA150, SATA150+NCQ, SATA300, SATA300+NCQ (default.)

!SIMULTANEOUS HOST CHANNEL VOLUME MAPPING

The RAIDBank4 can map a Volumeset to both host channels simultaneously for clustering environment. Never attempt to mount the same volume on both channels without proper clustering software.

Mounting the same volume on both channels without proper software can result in

data corruption or loss!

Press the UP/DOWN buttons to select the attributes. Press the ENT to modify each attribute of the default value. Using UP/DOWN buttons to select attribute value or press ENT to accept the default value. To complete the attribute definition, press ESC

3.1.5Enter the appropriate volume size to fit your application. Each volume set must have a selected capacity which is less than or equal to the total capacity of the RAID set on which it resides.

3.1.6Press ENT to select foreground initialization or ESC to select background initialization. Background initialization allows immediate access to the new volume but at an increase volume creation time. Foreground initialization does not allow access to the host until completion but at a faster completion rate.
