3.1 Drive Diagnostics

Note

You may determine the performance of drives attached to the FastStream using various displays and tests in ExpressNAV Storage Manager.

The following instructions assume you have already set up at least one RAID Group.

The ATTO FastStream collects various metrics to measure performance for physical drives attached to the FastStream during normal system operation and drive initialization and verification.

New performance data is updated every 60 seconds which impacts performance slightly, even if you minimize the browser window. Exit the ExpressNAV Storage Manager completely whenever you need maximum performance.

ATTO Technology Inc. FastStream SC Installation and Operation Manual

3.2 DriveAssure

DriveAssure™ is an ATTO exclusive combination of features that perform predictive and corrective actions to allow the continued operation of marginal drives, while ensuring continued, uninterrupted access to data. DriveAssure lets your storage run longer, faster and smoother without interrupting data flow while avoiding the unnecessary cost of replacing functional drives.

There are six different technologies which make up DriveAssure feature:

• Guaranteed Latency Response

• Rebuilds Continue on Error

• Initialization Media Scrubbing

• Media Scan + Parity Verification

• On-the-Fly Media Error Handling

• Data Recovery Mode

Guaranteed Latency

If there is a slow drive in a storage array, or an intermittently slow drive, or if a drive has a "slow spot", without extra processing this results in larger than usual delays. FastStream with DriveAssure™ technology, for parity and redundant RAID levels, compensate when one drive in a RAID Group does not respond within a specified period of time. The data from the drive can be generated using the parity or redundancy information from the rest of the RAID Group, with only a nominal change in throughput. In that way, the FastStream is forgiving of intermittent problems and can keep data moving smoothly.

Media Scan

A Media Scan reads all member drives and corrects Media Errors by calculating the expected data and rewriting it, so the drive can relocate it to a good sector. The 'verify' option adds a data integrity check by verifying that the data and parity match.

1 If you are not already in the ExpressNAV

Storage Manager, type the IP address of your controller in a standard browser. On the splash screen, click Enter Here. In the box provided, type in your user name and password, and click OK.

2The Health and Status page appears. Click

the Diagnostics button on the left hand menu.

3 Choose Media Scan.

Rebuild Continue on Error

In the event of a soft failure on a drive during a RAID Group rebuild, the FastStream will fix the drive issue, if possible, and continue the rebuild. This will allow rebuilds that occur overnight, during a holiday, or on a weekend, to continue providing additional protection against subsequent drive failures while unattended.

Initialization Media Scrubbing

Initialization Media Scrubbing is performed during Advanced Initialization. When new drives are connected to the FastStream for the first time, it is recommended that they go through Advanced Initialization. FastStream will write a pattern, completely, on all drives and reassign access to any blocks reported as bad and also attempt to fix any soft errors. This provides the most reliable media to create RAID Groups.

4 You may now choose to instantly Start,

Schedule, Display, Cancel or Pause a Media Scan operation. You may also choose to perform a Media Scan when you select Hot Spare drives.

To Start a Media Scan: 1 Select the Start option. 2 Click Next. 3 Select the Scan type - you may choose a Scan

6 Enter the frequency, date and time to schedule

the Media Scan.

7 Click Commit.

Enter time, day of week and 'daily' or 'weekly' to schedule a scan on a recurring basis.You may also view, reschedule and delete scheduled Media Scan events on this page.

Rebuild Recovery Mode

Rebuild Recovery Mode forces a rebuild to continue even when errors are present. When complete, the RAID Group is placed online and all data can be accessed; however, data needs to be verified to confirm that it is intact as a drive failure may have damaged some portion of data.

Basic Recovery Mode

Basic Recovery Mode attempts access to a RAID Group using any drive that was a member of that RAID Group. Although all data may not be recovered from a failed disk, existing data may be copied to a different RAID Group.

Extreme Recovery Mode

Extreme Recovery Mode is an advanced mode which allows RAID Group access in the event of multiple drive failures. Data may be beyond recall, depending on the failure mode of the drives, but attempts will be made to give you access to remaining RAID Group data.

On-the-Fly Media Error Handling

If a media error occurs on a drive during normal data transfers, the FastStream will reassign these blocks as well as attempt to fix soft errors during normal read and write data transfer operations.

Data Recovery Mode

In the event of an actual drive failure, Data Recovery Mode attempts to provide access to data to be copied to a new RAID Group. The option to force a rebuild to continue in this mode is also available. If there is a soft drive failure, it may be possible to continue using the RAID Group.

In the ExpressNAV menu: 1 Click the Diagnostics button. 2 Click Use Recovery Mode. 3 Click Next button.

All recovery modes should be used with care as they are powerful tools which if misused could cause additional problems. Default access is read-only, but write access is also available so that file system utilities can be used.

4.0 Configure Storage into RAID Groups

CAUTIONCAUTION

The ATTO FastStream allows configuration of storage into DVRAID, JBOD, RAID Level 0, 1, 1+0, 4, 5 or 6 with the ability to create multiple partitions.

RAID is a storage configuration which uses multiple drives to increase capacity, performance, and/or reliability. The FastStream can automatically set up an application-ready RAID configuration. Also, you may custom design a RAID configuration, or combine a custom and an automatic configuration.

The FastStream uses all available drives when you select
