the contents of the bundle on your local
workstation. Within the bundle you will find the
Driver VIB file (.vib) for your ATTO adapter.

2 Use the Datastore Browser in the vSphere

Client to upload the VIB file to your ESXi host.
Alternatively, you can use a program like
winscp on Windows or scp on Linux to upload
the file directly to your ESXi host.

3 Log in to the ESXi host on the Local Tech

Support Console (ESXi), or through an SSH
client.

4 Install the VIB using the following command on

the ESXi host:

Driver Configuration

# esxcli software vib install -v <full path to VIB file>

3 New Windows OS Installation

When you install a new or different copy of the Windows operating system on a disk attached to an ATTO
ExpressSAS adapter, you must reinstall the ATTO ExpressSAS drivers.

If you are changing the version of Windows you are
using or installing a fresh copy of your current version
onto your system, you must ensure Windows
recognizes your ATTO ExpressSAS and uses its
drivers.

You may create an installation media (disk, CD or USB
flash drive) from a file from the ATTO website, then
use that media to install the adapter and its driver to
the new version of Windows.

Follow these procedures after you have completed
installation of the ExpressSAS adapter and you have
connected storage devices (refer to
on page 15).

hexadecimal mask value is the sum of the event type
values for the events you would like to see.

The ATTO driver uses the system log to communicate
driver events to the user. Each event begins with a
driver and channel identifier,

event type 'Fatal' are significant; all others are mostly
for informational or diagnostic purposes. When
turning on event logging, be aware that certain events
reported as errors are expected. For example, a SCSI
Check Condition error will be reported for the first
command sent to a device after power on or a reset
condition. Also, certain data underrun errors are
expected by the software and are normal.

Note

Adaptive Path Optimization (ExpressSAS RAID only)

Often users need redundancy and improved performance. This can be achieved using dual SAS domains via
adaptive path optimization. In this configuration, multiple physical connections to drives are created to eliminate
pathway failure concerns (i.e. external cable failure, expander failure, RAID controller failure, or failure in a
spanned JBOD configuration), as well as to distribute data movement over all available connections to maximize
performance. To take advantage of multiple domains, devices must be dual-ported and cabled properly.

1 In a standard configuration, a single cable is

connected to a storage array (see Exhibit 6-1
for basic connectivity. As an alternative, most
SAS/SATA storage arrays have a second
connector for daisy chaining additional storage.
This connector may also be used to provide a
redundant connection from your ATTO
ExpressSAS RAID adapter (see Exhibit 6-1
This eliminates a single point of failure between
the adapter and storage and may also provide
a performance improvement. As a third option,
SAS drives have two connections to each drive
that can be used to provide even more options
for improved performance and redundancy. To
take advantage of this option, connect a cable
from your ExpressSAS RAID adapter to each
expander port on your storage array (see

Exhibit 6-1

Exhibit 6-1

Exhibit 6-2

).

Exhibit 6-3

)

).

Refer to documentation from your storage
array vendor for additional information on
cabling to your particular array.

2 Adaptive path optimization occurs when

multiple paths to a drive are available. It

automatically configures primary and alternate

paths for highest levels of redundancy, as well

as highest data transfer rates. Using event-

driven algorithms, it evaluates and adaptively

re-configures data path assignments for

optimal performance. No user intervention is

required for this feature. For the cost of a cable,

you get:

• Automatic configuration

• Redundancy and improved performance

• Path matching that is RAID Group aware

• Automatic and balanced failover/failover
capabilities.

• Stable configurations

Connecting an internal Mini-SAS to SATA
Fan-out cables

A mini-SAS to SATA fan out cable has a mini-SAS
connector (SFF-8087) on one end and four SATA
connectors on the other end. Plug the mini-SAS
connector into the appropriate 'Jn' connector on the
adapter. Plug each of the SATA connectors into the
drive backplane. The cable attached to each SATA
cable should have a number that indicates the
connection order within the mini-SAS connector. The
number on the cable indicates the order that the SATA
cable should be connected to drive slots on the
backplane. Consult the documentation for your

backplane to determine the relationship from the SATA
connector to drive slot.

Connecting an internal Mini-SAS to
internal Mini-SAS cables

A mini-SAS to mini-SAS cable has a mini-SAS (SFF-

8087) connector at each end of the cable. Plug one
end into the appropriate 'Jn' connector on the adapter.
Plug the other end into the appropriate connector on
the drive backplane. Consult the documentation for
your backplane to determine the relationship from the
Mini-SAS connector to drive slot.

LED Control for Internal SAS Connectors

This section provides the instructions that define the
cable connections needed to exercise LED Control for
hard drive backplanes. This section applies to the
following models: R608; R60F; H608; and H60F.
These adapters have been designed to support LED
Control functionality through an SGPIO interface or an
I2C interface. These interfaces require different cable
connections and those connections are specified in
this chapter.

Using SGPIO for LED Control

SGPIO with an internal mini-SAS to mini­SAS cable

The signals for SGPIO are included within the Mini­SAS connector located on the adapter. These signals
are routed to the hard drive backplane based upon the
cable used for the backplane connection. Consult the
documentation for your backplane to determine if it
supports SGPIO.

SGPIO with an internal Mini-SAS to SATA
Fan-out cables

Follow the instructions for a connection with internal
Mini-SAS to SATA Fan-out cables. The fan out end

should have an additional connector that is an 8 wire
connector. This connector must be connected to an
SGPIO header on the hard drive backplane. (See
Example 2) Consult the documentation for your
backplane to determine the relationship from the
SGPIO connector to the drive slots.

Note, the SGPIO sideband connector is not standard
and the connector must match the connector on the
backplane. Please see the backplane's and cable's
documentation for more details

Using SES-I2C for LED Control

The signals for LED Control via I2C are generated at
