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.

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.

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

with Parity Verify or Scan only.

4 Select the Target type - RAID Group or

Individual Drive.

5 Select the drives or RAID Group on which you

would like to perform a Media Scan. 6 Click Commit. 7 A Media Scan will begin immediately after you

finish the selection process.

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

SCSI Enclosure Services (SES)

Drive enclosures may have a SCSI Enclosure Processor which indicates enclosure health status, drive identification and drive fault identification.

The ATTO FastStream recognizes drive enclosures that provide SCSI Enclosure Services (SES).

Use SES to identify individual drives, all the drives in the same enclosure, all the drives in a single RAID

Group, or faulted drives, and to monitor the status of enclosure power supply(s), fan(s) and temperature sensor(s).

You may set up the FastStream to send notifications when certain events occur using page of the ExpressNAV Storage Manager.

You designate the person receiving notification of conditions and the level of severity which prompt notification using Email notification.

Error Notification

Types of errors

• Device/drive errors such as medium error, aborted command and hard error

• Device/drive transitions from online to offline

• Critical and warning temperature conditions

• Critical and warning voltage conditions

• Power recycle/power failure conditions

• Enclosure issues, when SES is Available

Email notification

Warning messages

• device down

• medium error

• abort command

Message severity levels

• Critical: critical event Emails

• Warning: warnings and critical event Emails are sent

• Informational: information which you may want to know but which probably does not require action: only information messages are sent

• All: warnings, critical events and informational messages

• None: no Emails are sent

Phone home Email notification allows the FastStream to send an Email message to you, a network administrator or other users when certain events occur with the FastStream.

Serious error messages are sent immediately, while messages for less serious errors are sent every 15 minutes.

You may send Emails to up to five Email addresses and designate which conditions prompt each Email notification.

For example, a recipient with a critical severity level only receives critical messages and not warning or informational messages.

When an event occurs that warrants Email notification, the FastStream sends the message; it cannot respond to a rejection by a server for an invalid address. Ensure all Email addresses typed in are valid.

Each Email is time stamped when it is sent as part of the SMTP header information.

6.3 CacheAssure

Note

CacheAssureTM is a maintenance-free, flash-based data protection feature that safeguards against the loss of cached data during a power or system failure. CacheAssure is optional on both Desktop and Embeddable models.

In the event of a power or system failure, CacheAssure instantly detects the failure and preserves the cached data in Non-Volatile memory, allowing users to maintain their data until power is restored. CacheAssure provides quick and easy access to cached data upon system re-boot by keeping the data in Non-Volatile memory until all the drives are ready to accept the transfer and data is verified. Competitive solutions immediately flush the cached data upon system re-boot, risking data loss in the event the drives are offline and not available.

CacheAssure requires no maintenance, no monitoring and no replacement. The power module charges in 10 minutes and the Non-Volatile (NV) Memory Module can then hold the data for up to 10 years. Once power is restored, the FastStream will write all cached data out to the drives. CacheAssure will be ready for another power disruption in just 10 minutes.

Benefits of CacheAssure

Lifetime Backup

data for up to 10 years, offering a more substantial return on investment. Typical battery backup units last approximately 1 or 2 years and only provide upwards of 72 hours of data protection.

- CacheAssure protects cached

to strict disposal regulations. This reduces the costs and the negative environmental effects associated with battery disposal.

CacheAssure Status

CacheAssure Status is displayed on the Health and Status Monitor page.

FastStream models with CacheAssure have disk write caching disabled by default. Disabling disk write caching ensures data integrity in the event of a power failure and can lower write performance of attached disk drives. Disk write caching can be enabled to override ATTO's recommended default setting while improving disk write performance. In the event of a power failure with disk write caching enabled there is a chance that data residing in the disk write cache during a power failure or catastrophic event will result in the loss of that data.

FastStream process: adding or removing Hot Spares

If a member of a RAID Group becomes degraded or faulted, you lose some redundancy in your RAID Group until a new member is rebuilt into the RAID Group. However, Hot Spare devices may be designated as replacements for faulted devices without intervention by you or a host.

You may set up a pool of Hot Spare devices of different sizes appropriate for your RAID Groups.

Hot Spares may be set up by the FastStream automatically depending on your choices during initial setup. There are two types of Hot Spares:

• Dedicated: Hot Spares that are dedicated solely for use with a specific RAID Group and may not be used by any other RAID Group

• Global: Hot Spares that may be used by any RAID Group.

• The FastStream replaces the faulted drive with the drive from the Hot Spare pool.

• The FastStream begins an automatic rebuild of the RAID Group(s).

A RAID rebuild may take up to two hours to complete.

1 Follow the instructions in Preliminary steps on

page 37 and click on the FastStream SC arrow from the Select User Process box.

2 Select the Add/Remove Hot Spares button.

Devices in the Hot Spare pool should be of appropriate size to the RAID Group so that smaller devices are not replaced by much larger Hot Spare devices, thus wasting storage capacity.

Drives will be searched for in this order: 1 Search for Dedicated Hot Spare

2 Search for Global Hot Spare (Smallest

available drive of sufficient size)

Configure Storage

JBOD: Just a Bunch of Disks

JBOD configuration allows many individual drives to be available for normal storage operations with no special data protection by combining several drives into one large drive. A special case of a RAID Group, multiple physical drives are assigned to a JBOD RAID

If a drive has corrupt or outdated configuration data, that drive cannot be assigned to any RAID Group. Ensure all drives are configured properly. Refer to page 15 or

on page 41.

A RAID Group is a virtual, independent single drive whose data is written to physical drives according to a RAID algorithm. The ATTO FastStream supports JBOD, DVRAID, RAID Level 0, 1, 1+ 0, 4, 5 and 6.

RAID improves data accessibility and reliability during normal operations, however, you still need a good backup strategy for long-term protection of your data.

RAID Level 1: additional mirror

RAID Level 0 (striping) is based on the fact that increased performance can be achieved by simultaneously accessing data across multiple drives, increasing data transfer rates while reducing average access time by overlapping drive seeks. Drives are accessed alternately, as if stacked one on top of the

other. RAID Level 0 provides no data protection. If one drive fails, all data within that stripe set is lost.

RAID Level 0 is used by applications requiring high performance for non-critical data.

The ATTO FastStream supports 2 to 16 drives per RAID Level 0 group.

RAID Level 1: mirroring (duplicate drives)

RAID Level 1 ensures the security of data by writing the exact same data simultaneously to two different drives. With RAID Level 1, the host sees what it believes to be a single physical drive of a specific size: it does not know about the mirrored pair.

This application is used for critical data which cannot be at risk to be lost or corrupted due to the failure of a single drive.

The ATTO FastStream supports an even number of 2 to16 drives per RAID Level 1 group.

RAID Level 1 plus additional mirroring

RAID Level 1 with multiple mirrors uses at least 3 drives with the same data on each drive. This application offers the highest fault-tolerance with good

performance, especially for small database applications.

RAID Level 1+0 increases data transfer rates while ensuring security by writing the exact same data simultaneously to two or more different drives.

RAID Level 1+0 is used in applications requiring high performance and redundancy, combining the attributes of RAID Levels 1 and 0.

The ATTO FastStream supports an even number of 4 to 16 drives per RAID Level 1+0 group.

RAID Level 4: striping, one parity drive

RAID 4 writes data across multiple drives or devices (striping) with parity blocks written to a single drive in the RAID Group. This increases reliability while using fewer drives than mirroring.

RAID Level 4 is best suited for applications that perform mostly sequential access such as video applications.

You must have at least three drives to set up RAID Level 4.

RAID Level 5: striping, parity distributed among drives

RAID Level 5 increases reliability while using fewer drives than mirroring by using parity redundancy: parity is distributed across multiple drives.

RAID Level 6 increases reliability for mission critical applications by striping both data and dual parity across multiple drives, writing data and parity blocks across all the drives in a RAID Group. RAID 6 can

tolerate failure of two drives and provides redundancy during rebuilds.

The ATTO FastStream requires at least four drives to build a RAID 6 group. Two drives per RAID Group are used for parity protection and are unavailable for data.

Appendix B Multipathing

To optimize storage availability and performance, it is recommended that you take advantage of failover and load balancing provided by host based multipathing.

The FastStream Storage Controller is compatible with generic multipathing for Windows, Mac OS X and Linux but is optimized for use with ATTO’s MultiPath Director

for Mac OS X, Linux and Windows.

Improved Availability of Storage with improved performance

Multipathing Failover:

used to create logical “paths” between the server and the storage device. In the event that one or more of these components fails, causing the path to fail, ATTO Multipathing logic uses an alternate path for I/O so that applications can still access their data.

Multipathing Load-Balancing:

multiple paths between the server and storage, thereby helping to remove bottlenecks and to balance workloads for better overall performance.

Redundant physical path components - host adapters, SFPs, cables and switches are

Multipathing software also serves to redistribute the read/write load among

Load Balancing algorithms provided by ATTO MultiPath Director for OS X and a DSM MPIO Driver for Windows Server

Pressure:

is domain based. The first level of path selection is based on the domain (adapter channel) with the fewest number of bytes being transferred. If there are multiple paths to a target on a domain, a second level of selection is used. Pressure load balancing provides the best (or equal) performance of all load balancing policies regardless of storage topology.

Queue Depth:

is not generally recommended for use in an environment with mixed I/O transfers to many devices.

Round Robin:

Depth, this target-based policy uses an I/O count for path selection; however the count is cumulative for all I/O in the current configuration (not the number of currently queued I/O’s). If an application issues an I/O down one path to a dual ported device, then issues another one five minutes later, the other path will be used.

The path with the fewest number of bytes being transferred is selected for I/O. Pressure load balancing

The path with the fewest outstanding I/O transactions is selected for I/O. This target-based policy

Data is distributed down all paths equally; the least-used path is selected for I/O. Like Queue

Appendix C Tape Pass-Through

A value added feature of the FastStream allows the pass-through of SAS connected tape devices. Connect these devices to a SAN Fibre Channel connection through the host ports on a FastStream Storage Controller.

Enable Tape Pass-Through

If you need to backup data through a fibre channel SAN, you would generally need a tape drive connected to a server. By moving your tape device to the SAN you can reduce overhead on your backup

server while RAID groups and tapes exist side by side without the need for extra hardware like a bridge or storage router. The FastStream allows all workstations to have access to tape storage for fast backups and restores.

To enable via commands:

• set passthroughmode all

• saveconfiguration restart

• routedisplay <topologytype> passthrough for example; "routedisplay sas passthrough" or "routedisplay fc passthrough"

Once passthrough is enabled, routes may be added manually for any passthrough device using "

sastargets

" and "

route

, use the following

• The get form returns the value of a parameter or setting and is an informational command.

• Responses to get commands are followed by Ready.

• The set form is an action that changes the value of a parameter or configuration setting. It may require a SaveConfiguration command and a restart of the system before it is implemented. The restart can be accomplished as part of the SaveConfiguration command or by using a separate FirmwareRestart command. A number of set commands may be issued before the SaveConfiguration command.

• Responses to set commands are either an error message or Ready. *. The asterisk indicates you must use a SaveConfiguration command to finalize the set command.

Use the Delete parameter with a SAS connector, PHY and LUN to delete a map. In verbose mode, overwriting a map requires secondary confirmation of the action. Possible values for conn are: (A - D). Possible values for phy are: (1 - 4).
