  • Page 8: Overview

    The current ExaSAN products employ PCIe3.0 protocol that provides 8 Gb/s per lane transfers. With 4 lane QSFP (Quad SFP) connector and cable, ExaSAN can transfer up to 32 Gb/s by using single connection. Post production work including non-linear editing (NLE) requires high bandwidth storage to quickly move the volume of data being processed and ExaSAN storage solution meets those demands.
  • Page 9 Whether it’s collaborative video editing in a post-production workgroup, or a shared research project in a university, the ExaSAN solution offers a range of performance levels and storage capacities that scale to meet the needs of small-to-medium-sized organizations. Equally important and useful is its integrated design, centralized administration and monitoring, and a suite of built-in management tools;...

  • Page 35: Preference

    5. RAID 4.5 Preference 4.5.1 Disk Lag Proof This feature ensures the stability and continuity of the RAID performance. In RAID 5 and RAID 6, DLP prevents the aging or slow responds of a single hard disk from influencing the overall performance.

  • Page 36: Ncq

    5. RAID In the event of performance degradation or delay of a single drive due to aging, the RAID system reads both data and parity stripes concurrently. It bypasses the slow reads and returns data to the host with the regenerated data and to provide stable performance based on the RAID parity.

    5. RAID 4.5.4 Beeper To enable/disable system beeper, default is enabled. 4.5.5 Equalization Mode Regardless the transmission method, the data transmission speed cannot be guaranteed at all times. This feature allows the continuous I/Os to operate more smoothly and substantially reduce large fluctuations in efficiency during data transfer.

  • Page 38: Misc

    5. RAID Caution Data in cache may be erased if power down unexpected. Suggest using a UPS (uninterruptible power supply) to prevent this scenario. Synchronize Cache – Check this box to enable cache synchronization with drives, to ensure all write data is correct, there is a frequently latency time within. For video capture, disable synchronization, because the video capture needs to be able to constantly write data to the RAID storage without long latency.
  • Page 39 5. RAID Password – Enter the new controller password. The default password is 00000000 (8 zeros). Type another 8 characters. Password Confirmation – Confirm the new controller password. Note: If you forget your password, you will have to contact your agent or the Accusys Support Team.

  • Page 40: Slicing

    5. RAID 4.6 Option 4.6.1 Slicing RAID slicing overcomes the inherent design of how data is stored on an drive or RAID system by subdividing a RAID array into segments, or slices. These slices are effective hardware partitions of all drives in the array. Each slice is a separate LUN and appears as a separate volume on the host computer.

  • Page 41: Lun Map

    5. RAID 1. Select the array by clicking on a drive with an array number. The capacity is displayed. By default, Slice 0 contains the entire capacity of the disk array. 2. Click on Slice 0, use the slide bar or button of percentage to slice space and click OK to confirm.

  • Page 42: Expansion

    5. RAID 1. Select the array to map by clicking on a drive with an array number. 2. Choose a LUN and from the drop down list select a slice to map to, check the Confirm box and click OK. 3.

  • Page 43: Migrations

    5. RAID Follow the steps below to select an array to expand. 1. Select the array to add additional drives, and select the number of drives to be added. A “+” sign appears above the drives to be added. 2. Check the Confirm box and click Expand Array. 4.6.4 Migrations Different from Expansion, which enlarges an array by adding hard drives to a fixed RAID level, Migration changes the RAID level of an array.

    5. RAID 4.6.6 Health Center To ensure the accuracy of the RAID parity data, RAID controller offers Background checking and “Rebuild parity data”. During checking or rebuilding parity, the performance of the array will be affected. You may check the progress in the Main view or in the Health Center. Follow the steps below to select an array to verify, rebuild, or condition.

  • Page 50: Unlock Drives

    5. RAID 4.6.7 Unlock Drives The RAID controller may lock abnormal drives in an array. You may unlock these drives and rejoin them in an array. Drives may be locked with one of two conditions: 1. If a drive returns data too slowly, the controller determines the drive is experiencing a failure and executes Drive Drop.
