Features: • • • • • • • • • • • Front-end 2-ported 4Gb FC ports with load-balancing & failover for high availability. RAID 6, 60 ready. Snapshot without relying on host software. (optional) SATA II drive backward-compatible. One logic volume can be shared by as many as 16 hosts.
RS16 FS – Manual v.6.1A usual without any impact to end users. The "on-the-box" implies that it does not require any proprietary agents installed at host side. The snapshot is taken at target side and done by ULTRASTOR controller. It will not consume any host CPU time thus the server is dedicated to the specific or other application. The snapshot copies can be taken manually or by schedule every hour or every day, depends on the modification.
RS16 FS – Manual v.6.1A LUN Logical Unit Number. A logical unit number (LUN) is a unique identifier which enables it to differentiate among separate devices (each one is a logical unit). GUI Graphic User Interface. RAID width, RAID copy, RAID row (RAID cell in one row) RAID width, copy and row are used to describe one RG. E.g.: 1. One 4-disk RAID 0 volume: RAID width= 4; RAID copy=1; RAID row=1. 2. One 3-way mirroring volume: RAID width=1; RAID copy=3; RAID row=1. 3.

RS16 FS – Manual v.6.1A values are available in export and not available in import which can avoid confliction/date-deleting between two controllers. That says if one controller already exists valuable data in the disks and user may forget to overwrite it. Use import could return to original configuration. If the volume setting was also imported, user’s current data will be overwritten. Figure 3.7.4.1 1. 2. Import: Import all system configurations configuration.
RS16 FS – Manual v.6.1A Figure 3.7.5.1 The event log is displayed in reverse order which means the latest event log is on the first page. The event logs are actually saved in the first four hard drives; each hard drive has one copy of event log. For one controller, there are four copies of event logs to make sure users can check event log any time when there is/are failed disk(s). Tips Please plug-in any of the first four hard drives, then event logs can be saved and displayed in next system boot up.
RS16 FS – Manual v.6.1A Chapter 4 Advanced operation 4.1 Rebuild If one physical disk of the RG which is set as protected RAID level (e.g.: RAID 3, RAID 5, or RAID 6) is FAILED or has been unplugged/removed, then the status of RG is changed to degraded mode, the system will search/detect spare disk to rebuild the degraded RG to a complete one. It will detect dedicated spare disk as rebuild disk first, then global spare disk. RS16FScontrollers support Auto-Rebuild.
RS16 FS – Manual v.6.1A Tips “Set dedicated spare” is not available if there is no RG or only RG of RAID 0, JBOD, because user can not set dedicated spare disk to RAID 0 & JBOD. Sometimes, rebuild is called recover; they are the same meaning. The following table is the relationship between RAID levels and rebuild. RAID 0 Disk striping. No protection for data. RG fails if any hard drive fails or unplugs. RAID 1 Disk mirroring over 2 disks. RAID 1 allows one hard drive fails or unplugging.
RS16 FS – Manual v.6.1A arrays. JBOD The abbreviation of “Just a Bunch Of Disks”. No data protection. RG fails if any hard drive failures or unplugs. 4.2 RG migration To migrate the RAID level, please follow below procedures. 1. 2. 3. Select “/ Volume configuration / RAID group”.

Weekly snapshot will be taken every Sunday 00:00. Monthly snapshot will be taken every first day of month 00:00. 4.4.3 Rollback The data in snapshot VD can rollback to original VD. Please follow the procedures. 1. 2. 3. Select “/ Volume configuration / Snapshot”.
RS16 FS – Manual v.6.1A 2. 3. 4. When making rollback, the original VD cannot be accessed for a while. At the same time, the system connects to original VD and snaps VD, and then starts rollback. During rollback, data from snap VD to original VD, the original VD can be accessed and the data in VD just like it has finished rollback. At the same time, the other related snap VD(s) cannot be accessed. After rollback, the other snapshot VD(s) after the VD which is doing rollback will be deleted.
RS16 FS – Manual v.6.1A top in “/ Volume configuration / Physical disk”. For example, Local, JBOD 1 (vendor model), JBOD 2 (vendor model), …etc. Local means disks in local controller, and so on. The disks in JBOD can be used as local disks. Figure 4.6.1 (Figure 4.6.1: Display all PDs in JBOD 1.) “/ Enclosure management / S.M.A.R.T.” can displays S.M.A.R.T. information of all PDs, including Local and all SAS JBODs.
RS16 FS – Manual v.6.1A Figure 4.6.2 (Figure 4.6.2: Disk S.M.A.R.T. information of Local and JBOD 1, although S.M.A.R.T. supports SATA disk only.) SAS JBOD expansion has some constraints as described in the followings: 1. 2. Up to 4 SAS JBODs can be cascaded. Created RG can not use PDs which located in different controllers. It means that RG can be composed of PDs which are all in Local or one SAS JBOD.
RS16 FS – Manual v.6.1A 3. Global spare disk only supports all RGs which located in the same controller. 4.7 Support Microsoft MPIO MPIO (Multi-Path Input/Output) use multiple physical paths to create logical "paths" between the server and the storage device. In the case which one or more of these components fails, causing the path to fail, multi-path logic uses an alternate path for I/O. So applications can still access their data.

RS16 FS – Manual v.6.1A Tips If the OS is 64bit, user can set the block size to any available value. If the OS is 32bit, user must change the block size to larger values than 512B. There will be a confirmation pop-up message when VD size is over 2TB. Figure D.1: (Figure D.1: choose “OK” for 64bit OS, choose “Cancel” for 32bit OS, this step will change block size to 4K automatically.) 2. Mouse moves to the gray button next to the VD number; click “More information”.
