Port Multiplier Compatibility When configured as a set of individual drives and connected to a SATA or an eSATA host adapter, the Port Multiplier will only work with a Port Multiplier aware host. This includes setting up the unit with more than one array. Identify your host controller and check with its hardware manufacturer if you are unsure. Addonics offers several Port Multiplier aware host adapters. Using identical drives for all settings other than JBOD or LARGE is strongly recommended

RAID 3 (Stripe set with dedicated parity) Number of drives: at least 3 Unit capacity: size of one member times number of members minus one. Spares: yes Fault tolerance: can withstand the loss of one drive without losing data. RAID 3 works by striping data for individual I/O blocks across all members except one, which contains parity data for the stripe set computed internally by the Port Multiplier. In the event of failure, the missing information can be calculated using the parity informatio

It should not harm individual drives or their contents; however, creating backups of all data is strongly recommended before proceeding.

Next, click the Basic RAID Configuration tab and select the type of RAID desired. Note that RAID 1 is currently disabled as an option since more than two individual drives are available, and DELETE ALL RAID is disabled since there are currently no arrays to delete. Shown below is the same set of drives being selected as a LARGE array. Finally, click Apply. The Jmicron RAID Manager will confirm the operation with a reminder that existing data on the drives will be lost, then perform the RAID

The RAID and Disk Information screen (shown when the program was launched) will now show the Port Multiplier with an Array. The drives are now listed as M0-M4, indicating they are members of the array. If spares are present (individual drives added later, and the EZ switch is in the OFF position), they would be listed as S0, S1, etc. On the right pane, the RAID Level, status, capacity and members that are online are listed. Status will show “Normal” (all members on line), “Degraded” (a fau
