Introduction
Infortrend storage systems are made of high quality and durable components based on a high-scalable hardware design,
providing support in terms of scalability and upgradeability. You also have the option to expand your storage system's
capacity with Infortrend's expansion enclosures in different form factors, allowing you more storage and provide quicker and
more efficient storage services without downtime.
The sections in this chapter list the expansion rules that you must follow when configuring the expansion enclosures with SAS
12 Gb/s drive-side models.
Overview of Maximum Drives
Infortrend provides various form factors that you can select for storage systems and expansion enclosures. The maximum
number of drives can be calculated based on the different models. Infortrend always uses SAS expansion technology to
implement massive drive scalability. Most of the products have onboard SAS ports to connect expansion enclosures and
some models support SAS expansion board to connect more expansion systems.
Take a look at the table below for Infortrend’s products, the maximum number of drives, and their supported interfaces:

Hybrid Expansion Enclosures
Infortrend allows some models to support hybrid expansion enclosure connections. The onboard SAS expansion port (either
dual or single port) supports up to 448 drives for each expansion chain, which is limited by the SAS chip used. Infortrend also
offers SAS 12 Gb/s expansion board for some models, which uses the same SAS chip as the onboard expansion ports. You can
use twice the supported number of drives of up to 896 (1792 for EonStor GS/GSc 5000) by cascading the second expansion
chain via the expansion host boards. Do note that not every model supports hybrid expansion enclosures configuration.
For the supported number of drives, see section Overview of Maximum Drives.
Systems that support hybrid expansion enclosures:
EonStor DS/GS/GSe family (12 Gb/s SAS drive-side models)
EonStor GSc family
EonStor GSe Pro 3000 series
Systems that do not support hybrid expansion enclosures:
EonStor DS/GS/GSe family (6 Gb/s SAS drive-side models)
EonStor GSa family
EonStor GSi family
EonServ family
EonStor GSe Pro 100/200/1000 series
Expansion Enclosure Number
Before setting up an extra expansion enclosure to an existing configuration, you must set the rotary ID switch using a
flat-blade screwdriver. Do note that each expansion enclosure must have a unique ID within an expansion chain. Currently,
the expansion enclosure's rotary ID switch is numbered from 1 to 15, which means you can only connect up to 15 expansion
enclosures per expansion chain.
IMPORTANT!
To prevent any ID conflicts, ensure that you set a unique ID to each expansion enclosure when connecting in a multi-array
environment.

Expansion Enclosure Connections
The sections in this chapter discuss the connections between expansions and storage systems with SAS 6 Gb/s and SAS 12
Gb/s technologies. Since the SAS drive-side protocol technology has been upgraded from SAS 6 Gb/s to SAS 12 Gb/s, the
operating storage system can use different SAS protocol for expansion.
SAS 12 Gb/s Storage System
For Infortrend storage systems with SAS 12 Gb/s drive-side, the onboard SAS expansion ports are marked as IN.
Figure 4: SAS 12 Gb/s Storage System Onboard Expansion Port
For any type of expansion enclosure, connect a SAS cable (blue) from the primary controller's SAS expansion port of the
storage system to the primary controller's OUT SAS port of the first expansion enclosure.
To configure the redundant paths in two daisy-chain topology, connect a SAS cable (orange) from the second controller's SAS
expansion port of the storage system to the second controller's SAS OUT port of the last expansion enclosure. Basic
connection rule when connecting systems in this connection type is IN to OUT, from the last expansion enclosure to the first
expansion enclosure.

SAS 6 Gb/s Storage System
For SAS 6 Gb/s drive-side storage system, the SAS expansion ports are marked as OUT.
Figure 9: SAS 6 Gb/s Storage System Onboard Expansion Port
For any type of expansion enclosure, attach a SAS cable (blue) from the primary controller's SAS OUT port of the storage
system to the primary controller's IN SAS port of the expansion enclosure.
To ensure redundancy in two daisy-chain topology, connect a SAS cable (orange) from the second controller's SAS expansion
port of the storage system to the second controller's IN SAS port of the last expansion enclosure. Basic connection rule when
connecting systems in this connection type is OUT to IN, from the last expansion enclosure to the first expansion enclosure.
Figure 10: SAS 6 Gb/s Storage System Expansion Connection
NOTE:
1. SAS 6 Gb/s to 12 Gb/s cables are required for SAS 12 Gb/s expansion enclosure connection.
2. Currently this configuration is only supported by the model that is newer than EonStor DS 1000. For G6 and G7/G7i
models, please refer to Previous G7/G7i Model Expansion Table and Previous G6 Model Expansion Table.

Model Classification (Single and Redundant)
Infortrend products, especially the high-availability models, are also classified by the number of controllers: single and
redundant. Redundant storage models are expandable via the redundant expansion enclosure. Single storage models, on the
other hand, are expandable via the single expansion enclosures. All single models of storage and expansion enclosures are
indentified by two letters: Sand G. Gmodels are not upgradeable to redundant (R) models, while Smodels are upgradeable
to redundant (R) models by installing a second Smodel controller. Take note that not every product supports Smodel.

Expansion Enclosure On-line Expanding
This chapter details the steps of adding expansion enclosures to an already present storage system setup.
Figure 12: Adding an expansion enclosure
1. Setting the expansion enclosure ID
The expansion enclosure ID is located at the front panel of the expansion enclosure. When setting expansion IDs, always set
them in order: Set the first expansion to 1, the second expansion ID in 2, and so on. The newly-added expansion enclosures
must be connected after the current setup's last expansion enclosure. Do take note that the enclosure IDs must be different
from each other.
Figure 13: Expansion enclosure ID
2. Installing the newly-added expansion enclosure
Due to the expansion enclosure's heavy weight, we recommend you to install the hard drives to the expansion enclosure
after the enclosure is already installed to the rack. After the ID assignment and installation of the expansion enclosures to the
rack, you can now connect the added expansion enclosures to the current system assembly via SAS cables.
In connecting the newly-added enclosures, ensure that the SAS cables are long enough to reach between SAS ports. The
longest cable is used to connect the storage system and the last expansion enclosure. In some cases, the expansion
enclosures are not directly installed on top or bottom of the storage system, so the cabling routes may vary. In most cases, at
least one long SAS cable is required.

Expansion enclosure 2
Expansion enclosure 3
(Newly added)

3. Reconnecting the redundant SAS path
(for redundant models only)
Unplug the SAS cable from the current last expansion controller (see dotted orange connection in Figure 9), then connect it
to the SAS port of newly-added last expansion's second controller (see longest orange cable connection in Figure 9). A longer
SAS cable may be required.
This step involves disconnecting one of the SAS cables, so critical events on storage system such as reports of drive-side
redundant path failure are expected. You will get notification events from the management GUI, LCD panel, LEDs, and other
means of notification alerts.
Figure 14: Redundant path failure of expansion enclosures in SANWatch
4. Connecting new SAS cable
Connect new SAS cables (see black connection) from the current last expansion to the newly-added expansion enclosure.
Ensure to follow the SAS connection's IN to OUT rule described in Expansion Enclosure Connections.
NOTE:
The sample diagram is only for SAS 12 Gb/s storage system.
5. Turning on the newly-added expansion enclosure
Press the power button to turn on the expansion enclosure, then wait for the storage management GUI to display the
additional expansion enclosure. Once the added subsystem is successfully working with the system assembly, the storage
system's status on the management, GUI, LCD panel, LED panel, and other status features are back to normal.
Do take note that adding a newly-added expansion enclosure also sets the Hot-Add feature, which may cause delay or pause
for about 10-20 seconds on the host I/O. The delay/pause time may vary depending on the operating system, drivers, and
other factors.

6. Installing the newly added drives
We recommend you to install the drives into the newly-added expansion enclosure after the enclosure is successfully
recognized by the storage system. After installing the drives to the enclosure, check the drives' status in the storage
management GUI. Once the drives appeared on the GUI, you can already use them in storage provisioning. For more details,
refer to the software manual.
IMPORTANT!
If SANWatch or Embedded RAIDWatch is used as a management tool for DS family, you must reload the mentioned
management tool after connecting the new expansion enclosure. If the management tool does not display the
newly-added enclosures, click Data Reload from the upper-right corner of the GUI to refresh the screen.
