Depending on the application you choose, the number of drives you choose and several other factors, you may have other choices to customize your FastStream to your particular needs.

Some features are customized by you only if you use the custom setup. Refer to on page 19.

V arious outcomes are available when Auto-Rebuild is enabled.

• If an existing RAID group member becomes faulted or unavailable, such as when a drive is pulled out from an array, the controller initiates a rebuild using an available unallocated drive.

• If the controller boots up with drives missing or faulted, the FastStream tries to switch them out automatically.

• If no unallocated drive is available, you must replace the faulted drive and a rebuild will begin. Hot Spares are not required, allowing the maximum number of drives for data storage.

However, if you require maximum fault tolerance, it is best practice to have a Hot Spare available to supply the unallocated drive for immediate use. Refer to FastStream process:

6.1 Remote System Monitoring

You may set up the FastStream to send notifications using Email when certain events occur.

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 Notifcation

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.

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.

Note

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)

When the ATTO FastS tream detects a faulted device:

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

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

Note

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

1 Follow the instructions in Preliminary steps on

page 34 and click on the FastStream SC arrow from the Select User Process box.

2 Select the Add/Remove Hot Spares button.

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

Note

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 14 or

data

on page 38.

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 0: striping, no redundancy

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 dat a 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 FastS tream supports an even number of 2 to16 drives per RAID Level 1 group.

RAID Level 1+0: striping, mirror spans two drives

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 FastS tream 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.

Appendix C Multipathing

For environments where storage availability and performance are important, it is recommended that you take advantage of the ATTO FastStream’s Failover and Load Balancing Functionality.

The FastStream Storage Controller is compatible with Generic Multipathing for Windows, OS X and Linux, however best results are achieved and supported with the A TTO Windows DSM MPIO driver and A TT O Celerity Multipathing for OS X.

Setup instructions for A TTO Celerity Multipathing for OS X and ATTO Windows DSM MPIO can be found on the A TTO Technology website Linux Multipathing can be found on the FastStream CD. If you are in need of an ATTO Celerity Host Adapter, please contact ATTO Sales at 716-691-1999 x240.

Setup of the FastStream with Multipathing

Multipathing functionality is setup and controlled from the Fibre Channel Host Adapter, minimal interaction is required on the FastStream. When the FastStream Storage Controller is used with any Multipathing technology, the FastStream must have the MultiNode functionality disabled. This can be set via the Advanced CLI page with the command “FCMultiNode disabled” or from the ExpressNAV Storage Manager from the Manage Menu -> System Configuration -> Establish Access through FC Ports (this must be set to Yes). No other setting changes are required in order for Multipathing compatibility.

Improved Availability of Storage with improved performance

Multi Pathing 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.

Multi Load-Balancing:

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

Pressure:

is domained 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:
