Chapter 1 RAID introduction 1.1 Features i Series features: • Gigabit LAN (x2) -to- SATA II (xN bays) RAID controller. • RAID 6 ready. • SATA II support with SATA I backward compatible. • N-way mirror. • On-line volume expansion and RAID level migration.
1.2 Terminology The document uses the following terms: RAID RAID is the abbreviation of “R edundant A rray of I ndependent D isks ” . There are different RAID levels with different degree of the data protection, data avai lability, performance to host environment.
WT W rite- T hrough cache write policy. A caching technique in which the completion of a wr ite request is not signaled until data is safely stored on non-volatile media. Each data is synchronized in both data cache and the accessed physical disks. WB W rite- B ack cache write policy.
iSCSI I nternet S mall C omputer S ystems I nterface. CHAP C hallenge H andshake A uthentication P rotocol. An optional security mechanism to contro l access to an iSCSI storage system over the iSCSI data ports. iSNS I nternet S torage N ame S ervice.
Chapter 2 Getting started 2.1 Before starting Before starting, prepare the following items. 1. Check the “Certification list” in Appendix A to confirm the hardware setting is fully supported. 2. Read the latest release notes before upgrading. Release notes accompany with release firmware.
The iSCSI target is the storage device it self or an appliance which controls and serves volumes or virtual volumes. The target is the device which performs SCSI commands or bridges it to an attac hed storage device. iSCSI targets can be disks, tapes, RAID arrays, tape libraries, and etc.

The above diagram describes the relation ship of RAID components. One VG (Volume Group) consists of a set of UDVs (User Data Volume) and owns one RAID level attribute. Each VG can be di vided into several UDVs. The UDVs from one VG share the same RAID level, but may have different volume capacity.

Enter “Volume group” to view the status of each volume group. • VG column description: Figure 3.6.3.1 (Figure 3.6.3.1: There is a RAID 0 with 2 ph ysical disks, named “V G-R0”, total size is 148GB, related to 2 UDV. Another is a RAID 5 w i th 3 physical disks, named “VG-R5”.
Status 2 “R” Æ R ebuild. This volume group is doing rebuilding. Status 3 “M” Æ M igration. This volume group is doing migration. RAID The RAID level of the volume group. The button next to the RAID level is “Migrate” fun ction. Click “Migrate” can add disk(s) to do expansion or change the RAID level of the Volume group.

• UDV operations description: Attach Attach to a LUN. Create Create a user data volume function. Delete Delete a user data volume function. 3.6.5 Cache volume Enter “Cache volume” function to view the status of cache volume.
• CV operations description: Create Create a cache volume function. Delete Delete a cache volume function. If there is no free space for creating a new dedicated cache volume, cut down the global cache size first. After resized, then dedicated cache volume can be created.
Figure 3.6.6.1 Figure 3.6.6.2 (Figure 3.6.6.2: UDV-01 is attache d to LUN 0 with every host can access. UDV-02 is attached to LUN 1 w i th only initiator not e named “iqn.1991 -05.com.microsoft:s1300n” can access.) • LUN operations description: Attach Attach a logical unit number to a user data volume.
Example 2 is to create two UDVs. One shares global cache volume, the other uses dedicated cache volume. Set a dedicated spare disk. • Example 1 Example 1 is to create two UDVs in one VG, each UDV uses global cache volume. Global cache volume is created after system boots up automatically.
Figure 3.6.7.2 (Figure 3.6.7.2: Creating a RAID 0 with 2 physi cal disks, named “VG-R0”. The total size is 148GB. Because of no related UDV th ere, free size still remains 148GB.) Step 2: Create UDV (User Data Volume). To create a data user volume, please follow the procedures.
Figure 3.6.7.4 (Figure 3.6.7.4: Create UDVs named “UDV-1” an d “UDV -2”, related to “VG-R0”, the size of “UDV-1” is 50GB, the size of “UDV-2” is 98GB. The status of these UDVs are online, write back, high priority with cache volume 383MB.

(Figure 3.6.7.7: Slot 5 is set as global spare disk.) Step 5: Done. They can be used as iSCSI disks. Delete UDVs, VG, please follow the steps. Step 6: Detach LUN from UDV. In “/ Volume config / Logical unit” , Figure 3.6.7.8 1. Select LUNs by clicking the c heckbox of the row, then click “ ”.
1. Select “/ Volume config / Volume group” . 2. Select a VG by clicking the checkbox of the row, make sure that there is no UDV on this VG, or the UDV(s) on this VG must b e deleted first. 3. Click “ “. There will pop up a confirmation page. 4.
Figure 3.6.7.9 1. Select “/ Volume config / Cache volume” . 2. If there is no free spac e for creating a new dedicated cache volume, cut down the global cache size first by clicking the button “ ” in the size column. After resized, click “ ” to return to cache volume page.
Figure 3.6.7.10 1. Select “/ Volume config / User data volume” . 2. Click “ ”. 3. Input a UDV name, choos e a VG Name, select Dedicated cache which is created at Step 1, and input the size for the UDV; decide the stripe height, block size, read/write mode and set priority, finally click “ “.
Step 4: Attach LUN to UDV. Please refer to Step 3 of Ex ample 1 to attach LUN. Step 5: Set dedicated spare disk. To set dedicated spare disks, please follow the procedures: 1. Select “/ Volume config / Physical disk” . 2. Select a VG from the list box, then select the free disk(s), click “ ” to set as dedicated s pare for the selected VG.
To free dedicated spare disks, please follow the procedures: 1. Select “/ Volume config / Physical disk” . 2. Select the dedicated spare disk by c licking the checkbox of the row, then click “ “ to free disk. Step 11: Delete dedicated cache volume.
5. LED status: 10 seconds. Figure 3.7.1 3.7.1 SES configuration SES represents S CSI E nclosure S ervices, one of the enclosure management standards. Enter “SES config” function can enable or disable the management of SES. Figure 3.7.1.1 (Figure 3.
Figure 3.7.2.1 If “Auto shutdown ” has been checked, the system will shutdown automatically when voltage or temperature is out of the normal range.
Figure 3.7.3.1 3.7.4 UPS Enter “UPS” function will set UPS ( U ninterruptible P ower S upply). Figure 3.7.4.1 Currently, the system only support and comm unicate with smart-UPS function of APC (American Power Conversion Cor p .) UPS. Please check detail from http://www.
(%) function. Shutdown Delay (s) If power failure occurred, and the system can not return back to the setting value period, the system will shutdown. Setting delay to “0” will disable the function. Shutdown UPS Select ON, when power is g one, UPS will shutdown by itself after the system shutdown successfully.
Figure 3.8.1 3.8.1 Upgrade Enter “Upgrade” function to upgrade firmware. Pl ease prepare new firmware file named “xxxx.bin” in local hard dr ive, then press “ ” to select the file.
3.8.3 Reset to default Enter “Reset to default” function, it allows user to res et controller to the factory default setting. Figure 3.8.3.1 Reset to default sets password to default: admin , and set IP address to default as Static IP. Default IP address: 192.
3.8.5 Shutdown Enter “Shutdown” function; it will display “Reboot” and “Shutdow n” buttons. Before power off, it’s better to press “S hutdown” to flush the data from cache to physical disks. The step is be tter for the data protection.
Chapter 4 Advanced operation 4.1 Rebuild If one physical disk of the VG which is set as protected RAID level (e.g.: RAID 3 , RAID 5, or RAID 6) is FAILED or has been unplugged/remov ed, then, the VG status is changed to degraded mode, the system will search/detect spare disk to rebuild the degraded VG to a complete one.
When rebuilding, the stat us of PD/VG/UDV is “R” ; and “R% ” in UDV will display the ratio in percentage. After complete rebuilding, “R” and “DG” will disappear. VG will become complete one. Tips The list box doesn’t exist if ther e is no VG or only VG of RAID 0, JBOD.
4.2 VG migration and expansion To migrate the RAID level, please follow the below procedures. If the VG migrates to the same RAID level of the original VG, it is expansion. 1. Select “/ Volume config / Volume group” . 2. Decide which VG to be migrated, click the button “ ” in the RAID column next the RAID level.
Figure 4.2.3 (Figure 4.2.3: A RAID 0 migrates to RAID 5, compl ete percentage is 2%.) To do migration/expansion, the total size of VG must be larger or equal to the original VG. It does not allow expanding the same RAID level with the same hard disks of original VG.
4. Extension starts. If UDV needs in itialization, it will display an “I” in “Status 3” and complete percentage of initialization in “R%” . Figure 4.3.1 (Figure 4.3.1: Extend UDV-R0 from 80GB to 90GB.) Tips The size of UDV extension mu st be larger than original.
