G-SPEED eS INSTALLATION GUIDE
1. INTRODUCTION
Thank you for purchasing G-SPEED eS from G-Technology,
Inc. (G-Tech)! Specifically designed for professional content
creation applications, G-SPEED eS features a high-speed
3Gbit/sec eSATA interface and provides RAID 0, 1, 5, 10 and
JBOD functionality when used in conjunction with the optional
G-Tech PCI Express (PCIe) RAID controller. Up to four
G-SPEED eS units can be attached to the G-Tech RAID
controller for storage capacities to 16 TB and data rates over
600 MB/sec. G-SPEED eS supports multi-stream video editing
workflows on Mac Pro workstations.
4. WHAT’S IN THE BOX
Take a moment to ensure that the following items are
included in the box. If anything is missing, please call G-Tech
at (310) 449-4599. Please keep the shipping container and
packing materials. In the unlikely event that you need to
return G-SPEED eS to us for any reason, you must use the
G-Tech shipping container. If the Product is returned
damaged caused by improper packaging, the warranty will be
void and liability will rest with the user.
If you purchased G-SPEED eS with the G-Tech PCIe
RAID controller, the system has been set up at the
factory in RAID 0 mode. The controller also supports
RAID 1, 5, 10 and JBOD modes. Refer to Section XX if you
wish to change the mode of operation.
2. SAFETY PRECAUTIONS
The disk drives contained in your G-SPEED eS are delicate
electronic instruments and are susceptible to damage due to
excessive physical shock. Place the unit in a vented area away
from moisture or liquids. Please handle the unit with care. Do
not open the case. Doing so will void the warranty. If the
Product is returned with damage caused by improper
handling, the warranty will be void and liability will rest with
the user.

G-SPEED eS INSTALLATION GUIDE
7. G-SPEED eS AUDIBLE ALARMS
7.1 The G-SPEED eS enclosure is equipped with an audible
alarm that sounds when:
1. The internal temperature of the G-SPEED eS enclosure
reaches a temperature of 60° centigrade
and/or
2. When the main FAN fails or the RPM of the fan slows to
a state where the fan can longer adequately cool the
system.
8. SETTING UP G-SPEED eS WITH THE G-TECH PCIe
RAID CONTROLLER
G-SPEED eS comes pre-configured in RAID 0 mode and
formatted for MAC OS X. Connecting G-SPEED to your Mac
Pro and configuring your system takes just a few steps as
outlined below.
8.1 Installing the G-Tech PCIe RAID Controller
1. Install the G-Tech RAID controller into SLOT 4 (top slot)
of your Mac Pro workstation.
In addition to the audible alarm, the Temperature/Fan
Warning LED located on the front bezel of G-SPEED eS
will illuminate.
If you hear an audible alarm and see the RED warning LED on
the front of G-SPEED eS, stop using G-SPEED eS immediately.
Check to see if the fan is spinning and move the unit to a
cooler location. If you require a new fan, contact G-Tech
Support for a replacement.
G-Tech PCIe
RAID Controller
7.2 The G-Tech RAID controller is also equipped with an
audible alarm that sounds when:
1. A disk drive failure occurs
2. Secure the RAID controller in place.
or
2. When the G-SPEED eS is removed from the RAID
controller without first selecting “Unplug” in the Array
Maintenance menu in the web GUI.
NOTE: If you are using an AJA, Blackmagic Design or
equivalent video capture card, install it in SLOT 3
unless otherwise instructed by the card vendor.
If you hear an audible alarm coming from the G-Tech RAID
controller, see Section 12 “What to do in the Event of a Disk
Drive Failure”. See Appendix A.1.7.2 for information on the
proper way to hot “Unplug” G-SPEED eS.

Description
Disk striping
Mirroring
Disk striping
with
distributed
parity
Advantage
Offers the highest
performance and a
useable storage
capacity of 100%
of total available
storage capacity
Maximum level of
data protection as
identical data is
written to multiple
drives
High read
performance,
medium write
performance with
data protection in
case of a drive
failure.
Disadvantage
No fault tolerance failure of one drive
in the array results
in complete data
loss
Ideal For…
Content creation
applications
requiring highest
storage capacity
Useable storage
space is 50% of
total available
capacity
Applications in
which data
security is
paramount
Useable storage
capacity equals
total capacity of all
drives in the array
less the capacity of
one drive.
Content creation
applications
requiring data
protection
When the G-Tech web GUI is open dropped frames
may occur in editing applications such as Final Cut
Pro. We recommend not having the GUI open while
working in these programs.
It is recommended not to exceed the standard eSATA
cable length of 1 meter (3 feet).
Up to (4) G-SPEED eS storage units can be attached
to the G-Tech RAID controller for up to 16TB of
capacity and over 600 MB/sec of performance.
Replacements / extra G-SPEED eS disk modules are
available for purchase online at:
www.g-technology.com/products/g-speed-es.cfm
For example, a 4x
1TB RAID 5 yields
a useable capacity
of 3 TB.
