The ATTO FastStream initialize and verify drive feature discovers and re-maps bad sectors on drives providing reliable media for your RAID groups.

Before creating any RAID group you should initialize and verify the drives selected to be in the RAID group to ensure drive integrity. When selected, the FastStream writes a pattern to the entire drive, verifying the drive’s readiness and reliability.

CAUTIONCAUTION

Selecting Drive Initialization causes all previous storage data on the drive to be erased. Make sure all of your information is backed up before initializing drives.

During initialization and verification, the FastStream collects performance measurements. Performance data is available once initialization begins. You may view it from the page accessible from the performance data is lost when the appliance is powered off.

You may check drive integrity after you have created RAID groups on drives in RAID groups or drives which you wish to add to your FastStream configuring using the initialize and verify procedure or using a read-only scan of drives.

The read-only drive test performs a non-destructive scan over the entire surface of each drive to identify bad areas of disk drives and determine read performance. It may be run while data is passing through the FastStream.

Running this test may negatively impact performance. Once the read-only test has completed, system operation returns to normal.

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.

• 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

• Warning messages

informational messages are sent

•

None: no Emails are sent

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.

A RAID group may have several Terabytes of total data capacity because of the size of the included drives. Partitions allow you to break up large RAID groups into smaller, more manageable groups.

Health and

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.

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.

When the ATTO FastStream detects a faulted device:

• The Controller searches the Hot Spare pool for

the smallest block device of sufficient size to substitute for the faulted drive.

• 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).

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

Removing RAID configuration data

If you move single drives between devices without erasing the drives, you may want to clean stale RAID configuration data from the drives, permanently removing the drive from the RAID group. Drives must belong to a RAID group now or have once belonged to a RAID group and are labeled scans.

CAUTIONCAUTION

Continue with extreme caution: data is lost on the drive when it is cleaned of RAID information.

8.0 Manage ATTO Devices, Configurations

You may save the current configuration of your FastStream SC, use a configuration from another FastStream, or change the configurations of other ATTO devices from your current browser using the ExpressNAV Storage Manager.

If you have other ATTO devices in the same broadcast domain with no routers between them, and any switches between this FastStream and the other devices are configured to forward UDP broadcast messages, you may physically identify these devices and manage them from within the browser you are currently using.

You may also save the configuration of the FastStream you are currently using, or restore it from a previously-saved configuration, or import a configuration from another ATTO FastStream.

It is best practice to give your current FastStream a recognizable name so that you can distinguish it more easily from among other ATTO devices.

Creating a unique name for your FastStream

You may wish to name your FastStream if you are going to manage several ATTO devices from one browser.

Appendix B Design RAID Groups

The ATTO FastStream provides instant hardware data protection and intelligence to existing storage independent of the storage type.

CAUTIONCAUTION

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

To set up RAID groups refer to

into RAID Groups

The ATTO FastStream allows RAID functionality. In general, the process begins with individual drives called block devices.

on page 13.

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

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 11 or

data

on page 35.

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 and 5 for all models and RAID Level 6 for the FastStream SC

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 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.

Appendix C SCSI Cabling

Additional information to physically connect ports to devices and to your SAN.

SCSI cables and devices must be chosen to maximize performance and minimize the electrical noise from the high-speed data transfers available with the SCSI protocol. Cabling and termination methods become important considerations for proper performance. SCSI cables and devices are subject to specific length and number limitations to deal with electrical problems that arise at increased operating speeds.

Cable types

Use high-quality cables rated for the type of SCSI transfers required: well-insulated SCSI cables ensure error free communications.

Try to keep cable lengths as short as possible to ensure higher signal quality and performance. See

Exhibit A-2

on page xxiv.

Note

UltraSCSI is very sensitive to SCSI bus noise, cable distances and the number of devices connected on the SCSI bus. Carefully connect your devices when working with UltraSCSI.

Connecting SCSI devices to SCSI ports

SCSI ports connect SCSI storage devices to the network. Each SCSI port is totally independent from the other SCSI port.

Each SCSI port is a bus capable of supporting 16 devices and each bus is capable of 40, 80 or 160

MB/sec. (Ultra, Ultra2, Ultra160 or Ultra 320) transfer rates.

Each SCSI bus auto-negotiates the appropriate sync rates with the connected devices. If slower devices are mixed with faster devices, the bus communicates at the rate of the slowest device, thus wasting the performance capabilities of the faster devices. Connect slower devices to one SCSI port and connect faster devices to the other port.

The FastStream supports a wide variety of SCSI storage devices including stand-alone and removable drives.

1 Connect the cable from the SCSI device to a

SCSI port on the FastStream. 2 Check the type of cable, cable length limit and

number of devices recommended for the port.

See Exhibit A-2

Keep cable lengths as short as possible to

ensure the highest signal quality and performance. These cable lengths include the wiring inside the devices.

3 Set the IDs of the SCSI devices connected to

the FastStream to a value other than 7.

Use a sequential ID starting at 0 for each device.

The SCSI port has an internal factory setting ID of 7, typical for a SCSI initiator device.

4 Terminate the SCSI bus after the last device.

The FastStream is terminated internally.
