96-30065-001 Rev. A0 DataDirect Networks EF4024 FC RAID System Setup Guide | 9

The EF4024 FC RAID system is a 2U enclosure that supports 24 2.5" small form factor (SFF)
disks. It can be used as either a controller enclosure or expansion enclosure.

Each controller enclosure includes two controller modules while the expansion enclosures
include dual expansion I/O modules (IOMs). Both types of enclosure are equipped with two
redundant power and cooling modules.

1.1 Front Panel Components

Figure 1 illustrates the front of an EF4024 enclosure with the bezel installed. The enclosure

status LEDs and enclosure ID LED are visible through the front bezel.

There are 24 disk bays at the front of the enclosure. Figure 2 illustrates the LEDs on the front

1.2.2 Power and Cooling Module

Power redundancy is achieved through two independent load-sharing power supplies. In the
event of a power supply failure, or the failure of the power source, the storage system can
operate continuously on a single power supply. Greater redundancy can be achieved by
connecting the power supplies to separate circuits.

Refer to Appendix A for LED descriptions on power and cooling modules.

1.3 Expansion Enclosure Rear Panel

The EF4024 storage capacity can be increased by daisy-chaining expansion enclosures to the
controller enclosure. Up to three expansion enclosures are supported.

Figure 5 shows the rear panel of an EF4024 expansion enclosure. Each expansion enclosure

includes two expansion modules and two power and cooling modules. Refer to Appendix A
for LED descriptions.

Figure 6 illustrates the I/O ports on an expansion module.

Figure 6. Expansion Module

1.4 Cache

To enable faster data access from disk storage, the following types of caching are performed:

• Write-back or write-through caching. The controller writes user data into the cache
memory in the controller module rather than directly to the disks. Later, when the
storage system is either idle or aging —and continuing to receive new I/O data—the
controller writes the data to the disks.

Service Port

Expansion Module B

SAS In Port

Power and Cooling Module

SAS Out Port

• Read-ahead caching. The controller detects sequential data access, reads ahead into the
next sequence of data—based upon settings—and stores the data in the read-ahead
cache. Then, if the next read access is for cached data, the controller immediately loads
the data into the system memory, avoiding the latency of a disk access.

TIP:

See “Volume cache options” and “System cache settings” in the EF4024 RAIDar
User Guide for setting options.

96-30065-001 Rev. A0 DataDirect Networks EF4024 FC RAID System Setup Guide | 12

1.5 CompactFlash

During a power loss or controller failure, data stored in cache is saved off to non-volatile
memory (CompactFlash). The data is restored to cache, and then written to disk after the
issue is corrected. To protect against writing incomplete data to disk, the image stored on the
CompactFlash is verified before committing to disk.

The CompactFlash card is located at the midplane-facing end of the controller module as
shown in Figure 7. It is used for cache recovery only.

Figure 7. CompactFlash Card in Controller Module

System Components

CompactFlash Card

CAUTION :

IMPORTANT:

The CompactFlash card should only be removed for transportable

purposes. To preserve the existing data stored in the CompactFlash, you
must transport the CompactFlash from the failed controller to the
replacement controller. Failure to do so will result in the loss of data
stored in the cache module. The CompactFlash must stay with the same
enclosure. If the CompactFlash is used/installed in a different enclosure,
data loss/data corruption will occur. Contact DDN Support for guidance
on replacement procedure.

In dual-controller configurations featuring one healthy partner
controller, there is no need to transport failed controller cache to a
replacement controller because the cache is duplicated between the
controllers (subject to volume write optimization setting).

1.6 Supercapacitor Pack

To protect controller module cache in case of power failure, each controller enclosure
model is equipped with supercapacitor technology, in conjunction with CompactFlash
memory, built into each controller module to provide extended cache memory backup time.

The supercapacitor pack provides power for backing up unwritten data in the write cache
to the CompactFlash, in the event of a power failure. Unwritten data in CompactFlash
memory is automatically committed to disk media when power is restored. In the event of
power failure, while cache is maintained by the supercapacitor pack, the Cache Status LED
flashes at a rate of 1/10 second on and 9/10 second off.

enclosure

96-30065-001 Rev. A0 DataDirect Networks EF4024 FC RAID System Setup Guide | 15

2.2 Connecting the Enclosures

The EF4024 controller enclosure supports up to three expansion enclosures, or a maximum
of 96 disk drives. The EF4024 enclosures support both straight-through and reverse SAS
cabling. Reverse cabling allows any drive enclosure to fail—or be removed—while
maintaining access to other enclosures. Fault tolerance and performance requirements
determine whether to optimize the configuration for high availability or high performance
when cabling. The EF4024 controller modules support both 3-Gbps and 6-Gbps internal disk
drive speeds together with 3-Gbps and 6-Gbps expander link speeds.

Installing Enclosures

CAUTION :

Cabling diagrams in this section show fault-tolerant cabling patterns. Controller and
expansion modules are identified by <enclosure-ID><controller-ID>. When connecting
multiple drive enclosures, use reverse cabling to ensure the highest level of fault tolerance,
enabling controllers to access remaining drive enclosures if a drive enclosure fails.

For example, Figure 10 shows reverse cabling, wherein controller 0A (with enclosure-ID=0;
controller-ID=A) is connected to expansion module 1A, with a chain of connections
cascading down (blue cable). Controller 0B is connected to the lower expansion module (B)
of the last drive enclosure in the chain, with connections moving in the opposite direction
(green cable).

Some 6-Gbps disks might not consistently support a 6-Gbps transfer
rate. If this happens, the system automatically adjusts transfers to those
disks to 3 Gbps, increasing reliability and reducing error messages with
little impact on system performance. This rate adjustment persists until
the controller is restarted or power-cycled.

2.2.1 Cable Requirements

The expansion enclosures, supporting 6 Gb internal disk drive and expander link speeds, can
be attached to an EF4024 controller enclosure using supported mini-SAS to mini-SAS cables.

The EF4024 enclosures support 6-Gbps or 3-Gbps expansion port data rates. Use only
DDN-qualified cables, and observe the following guidelines:

• When connecting SAS cables to expansion modules, use only supported mini-SAS x4
cables with SFF-8088 connectors supporting your 6 Gb application

• Qualified mini-SAS to mini-SAS cables are used to connect cascaded enclosures in the
rack; the “mini-SAS to mini-SAS” cable designator connotes SFF-8088 to SFF-8088
connectors

• The maximum expansion cable length allowed in any configuration is 2 meters (6.56')

• Cables required, if not included, must be separately purchased

• When adding more than two drive enclosures, you may need to purchase additional
1-meter or 2-meter cables, depending upon number of enclosures and cabling method
used; spanning 3 or 4 drive enclosures requires 1-meter (3.28') cables

• You may need to order additional or longer cables when reverse-cabling a fault-tolerant
configuration (see Figure 10).

• Use only DDN-qualified cables for host connections

2.3 Powering On and Powering Off

Note the following before powering on the enclosures for the first time:

• Install all disk drives in the enclosure so the controller can identify and configure them
at power-up

Expansion
Enclosure 1

Expansion
Enclosure 2

Expansion
Enclosure 3

• Connect the power cords to the enclosures (as described in Section 2.3.1)

• Generally, when powering up, make sure to power up the enclosures and associated
data host in the following order:

❖ Expansion enclosures first

This ensures that the disks in the expansion enclosures have enough time to
completely spin up before being scanned by the controller modules within the
controller enclosure.

While enclosures power up, their LEDs blink. After the LEDs stop blinking—if no
LEDs on the front and back of the enclosure are amber—the power-on sequence is
complete, and no faults have been detected. See Appendix A for LED descriptions.

96-30065-001 Rev. A0 DataDirect Networks EF4024 FC RAID System Setup Guide | 18

❖ Controller enclosure next

Depending upon the number and type of disks in the system, it may take several
minutes for the system to become ready.

❖ Data host last (if powered down for maintenance purposes)

TIP:

In general, when powering off, you will reverse the order of steps used for
powering on.

2.3.1 Powering on the System

To power on the system:

1. Connect one end of the power cords to the power cord connectors on the back of all
expansion enclosures (Figure 11). Only the power cords supplied with the enclosures

should be used.

Figure 11. Power Cord Connector on Power Supply Modules

Installing Enclosures

Power Cord Connector

2. Connect the other end of the power cords to the rack power source (Figure 12). For
redundancy, connect the two power supplies to separate power source.

Figure 12. Connect Power Cords to Rack Power Source

3. Allow a couple of minutes for the disks to spin up.

4. Similarly, connect the power cords between the controller enclosure’s power supplies

and the rack power source. Only the power cords supplied with the enclosures should
be used.

96-30065-001 Rev. A0 DataDirect Networks EF4024 FC RAID System Setup Guide | 19

2.3.2 Powering off the System

1. Stop all I/O from hosts to the system (see Section 5.3, Stopping I/O on page 35).

2. Shut down both controllers using one of the two methods below:

❖ Use RAIDar to shut down both controllers, as described in the EF4024 RAIDar

User Guide

❖ Use the command-line user interface (CLUI) to shut down both controllers, as

described in the EF4024 CLUI Command Reference Guide

3. Turn off the controller enclosure by unplugging the power cords from the rack power
source.

4. Turn off all expansion enclosures by unplugging the power cords from the rack power
source.

Chapter 3

3.0Connecting Hosts

96-30065-001 Rev. A0 DataDirect Networks EF4024 FC RAID System Setup Guide | 21

This chapter provides information on how to connect your hosts to the EF4024 FC RAID
system.

3.1 Host System Requirements

Hosts connected to an EF4024 controller enclosure must meet the following requirements:

• Depending on your system configuration, host operating systems may require that
multipathing is supported.

• If fault tolerance is required, then multipathing software may be required. Host-based
multipath software should be used in any configuration where two logical paths
between the host and any storage volume may exist at the same time. This would
include most configurations where there are multiple connections to the host or
multiple connections between a switch and the storage.

Use native Microsoft MPIO DSM support with Windows Server 2008 and Windows
Server 2013. Use either the Server Manager or the command-line interface (mpclaim
CLI tool) to perform the installation.

See the following web sites for information on using native Microsoft MPIO DSM:

http://support.microsoft.com/gp/assistsupport
http://technet.microsoft.com (search for “multipath I/O overview”)

Connecting Hosts

3.1.1 Cabling Considerations

Common cabling configurations address hosts, controller enclosures, drive enclosures, and
switches. Host interface ports on EF4024 controller enclosures can connect to respective
hosts via direct-attach or switch-attach.

Qualified options support cable lengths of 1 m (3.28'), 2 m (6.56'), 5 m (16.40'), 15 m (49.21'),
30 m (98.43'), and 50 m (164.04') for OM4 multimode optical cables and OM3 multimode FC
cables, respectively. A 0.5 m (1.64') cable length is also supported for OM3.

3.2 Connecting Enclosures to Hosts

A host identifies an external port to which the storage system is attached. Cable connections
vary depending on configuration. This section shows a few common cabling configurations.

NOTE :

ULP can show all LUNs through all host ports on both controllers, and the interconnect
information is managed by the controller firmware. ULP appears to the host as an
active-active storage system, allowing the host to select any available path to access the
LUN, regardless of vdisk ownership.

EF4024 controllers use Unified LUN Presentation (ULP)—a controller feature
enabling a host to access mapped volumes through any controller host
port.
