ESU2-RD e-SATA & USB 2.0 to Dual SATA RAID Bridge Board Brief Overview and Instructions: Please make sure to have a paper clip handy when changing Raid modes as the reset button does require to be pressed for 5 sec. This is done for security reasons so customers do not delete their data just by switching the selection knob. The ESU2-RD is a unique hardware SATA RAID that can be configured without any operating system or graphical user interface. Simply turn the configuration knob on the back of the card, and press the change configuration button, and the board will automatically reconfigure the SATA RAID settings. For best results, you should delete any partitons that already exist before changing modes. Please note that data on the two disks will be lost by changing the RAID configuration, and you will have to create and format partitions on the volumes that are created. By default, safe RAID 1 partitions are set to rebuild automatically, if the controller finds that it is necessary. In case of a rebuild, the link light for the drive that is being rebuilt will blink on and off steadily, and the activity lights should be almost constant for both drives. If you set the configuration knob to GUI mode, you will be able to manage the RAID configuration with the Silicon Image SteelVine RAID management software. Settings: There are 6 RAID settings available. Hardware RAID with USB 2.0 and eSATA host connection Theis is a self contain storage solution for digital home and small office storage enviroment. It is a plug and Play hardware raid device and no driver or RAID configuration utility needed. Easy to use USBG-2RAID1W designs with no IT requirement in mind, just plug and ready to use in any configuration. Change raid mode? Easy enough! Rotate the dial on the back of the unit to: BIG, SAFE, FAST, SAFE, SAFE33, SAFE50, JBOD, or GUI push the CHANGE MODE button - case will change mode with 30 second. PLEASE NOTE: Any storage policy that has more than one volume (including JBOD), requires a SATA II Port Multiplier-Aware Host Controller, when using the eSATA connection. BIG The BIG storage policy concatenates a series of physical hard drives as a single large volume; resulting in a seamless expansion of virtual volumes beyond the physical limitations of singularly connected hard drives. SteelVine BIG storage policy delivers maximum storage space without a single large capacity and costly hard drive. It is also possible to create a BIG volume using only a single hard disk drive connected to Port 0, and then increase the storage capacity of the volume later by adding another hard disk drive (or another SteelVine Storage Processor with at least one hard disk drive) to Port 1 and pressing the Mode Change push-button. The new disk blocks of Port 1 will be concatenated to the end of the disk blocks of Port 0, and any data that is stored on the existing BIG volume will be preserved. However, it is not possible to expand an existing BIG volume by adding another hard disk drive to Port 0 and still preserve any existing data on that volume. JBOD The JBOD (Just a Bunch of Disks) storage policy enables each hard drive to be seen separately as one drive. When using a SATA host controller, JBOD should only be used if the SATA host controller provides Port Multiplier (PM) support. If a host is not PM-aware, only a single drive is presented (drive 0). No such limitation if using a USB host connection. FAST The FAST storage policy distributes access across all hard disks, also called striping (equivalent to RAID 0). FAST presents the best data speed but no data redundancy. FAST storage policy accelerates hard disk operating speed by using many disks in parallel. Hard drive data segments are written to different disks simultaneously which increases performance while sacrificing data redundancy. To implement the FAST storage policy, the SteelVine Storage Processor creates a single virtual volume that is striped across both hard drives, with a storage capacity that is equal to the sum of both hard disk drives. SAFE The SAFE storage policy stores all data in duplicate on separate drives to protect against data loss due to drive failure. One drive mirrors the other at all times, equivalent to RAID 1. Every write operation goes to both drives. SAFE provides the highest level of data protection for critical data that you cannot afford to lose if a hard drive fails, but halves the amount of storage capacity because all data must be stored twice. The resulting storage capacity of the virtual SAFE volume will be equivalent to the size of one hard drive (if both drives are the same) or the smaller of the two drives (if they are different). If one drive fails, the SAFE volume is still usable, but it is in a vulnerable state because its mirrored hard drive is inaccessible. When the offline drive comes back online, the appliance begins a rebuild process immediately to restore data redundancy. A message box appears in the GUI to notify you that a rebuild is in progress. Although the volume remains available during the rebuild process, the volume is susceptible to data loss through damage to the remaining drive until redundancy is restored at the end of the rebuild and verification process. Host access takes precedence over the rebuild process. If you continue to use the SAFE volume during the rebuild, the rebuild process will take a longer time to complete, and the host data transfer performance will also be affected. It is also possible to create a SAFE volume using one hard disk drive connected to Port 0 of the SteelVine Storage Reference Design, although no mirroring will occur until a second hard disk drive is connected to Port 1. With only one hard disk drive connected, the SAFE volume will be available, although no data protection will be provided until a second hard disk drive is connected. SAFE33 The SAFE33 storage policy creates two virtual volumes; one SAFE volume and one BIG volume, and should be used when you need the high reliability for some of your data (with the added overhead of mirroring) but you dont need high reliability for the remainder of your data. SAFE33 reduces the cost of additional hard drives in operations where non-critical data could be lost without severe consequences. SAFE33 uses a SAFE volume that is mirrored across two hard drives to protect your critical data in the event a hard drive failure. If one drive fails the SAFE volume is retrievable although the BIG volume is not. When you replace the failed drive, the SAFE volume is automatically rebuilt on to the replacement drive. The size of the SAFE volume of a SAFE33 policy will be one-third of the size of one hard drive (if they are equal) or one-third of the size of the smaller (if they are not equal.) The size of the BIG volume will be the combination of all remaining capacities. When using a SATA host connection, you must have a PM (Port Multiplier) aware host adapter. If your SATA host adaptor is not PM aware, then ONLY the SAFE volume will be detected and the BIG volume will not be accessible. No such limitation exists when using a USB host connection. SAFE50 The SAFE50 storage policy creates two virtual volumes; one SAFE volume and one BIG volume, and should be used when you need the high reliability for some of your data (with the added overhead of mirroring) but you dont need high reliability for the remainder of your data. SAFE50 reduces the cost of additional hard drives in operations where non-critical data could be lost without severe consequences. SAFE50 uses a SAFE volume that is mirrored across two hard drives to protect your critical data in the event a hard drive failure. If one drive fails the SAFE volume is retrievable although the BIG volume is not. When you replace the failed drive, the SAFE volume is automatically rebuilt on to the replacement drive. The size of the SAFE volume of a SAFE50 policy will be one-half of the size of one hard drive (if they are equal) or one-half of the size of the smaller (if they are not equal). The size of the BIG volume will be the combination of all remaining capacities. When using a SATA host connection, you must have a PM (Port Multiplier) aware host adapter when using SAFE50 on the top level node of a cascaded configuration so that ALL volumes can be detected by the host. If your SATA host adaptor is not PM aware, then ONLY the SAFE volume will be detected and the BIG volume will not be accessible. No such limitation exists when using a USB host connection.
