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 c
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.

• 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.

1.6 Super-Capacitor Pack

To protect controller module cache in case of power failure, each controller enclosure
model is equipped with super-capacitor technology, in conjunction with CompactFlash
memory, built into each controller module to provide unlimited cache memory backup time.
The super-capacitor pack provides energy for backing up unwritten data in the write cache
to the CompactFlash, in the event of a power failure. Unwritten data in CompactFlash
memory are automatically committed to disk media when power is restored. In the event of
power failure, while cache is maintained by the super-capacitor pack, the Cache Status LED
flashes at a rate of 1/10 second on and 9/10 second off.

2.2 Powering on/Powering Off

Before powering on the enclosure for the first time:

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

• Connect the cables and power cords to the enclosure as explained in the installation
sheet.

Installation

NOTE :

PSUs power on when connected to a power source, and power off when disconnected.

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

- Drive enclosures first

- Controller enclosure next

- Data host last (if powered down for maintenance purposes).

TIP :

powering on.

Newer AC power supply units (PSUs) do not have power switches. Switchless

This ensures that the disks in the drive enclosure 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

3.1 Host System Requirements

Hosts connected to an EF3015 controller enclosure must meet the following requirements:

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.

• For Windows Server 2003, use the MPIO DSM available from DDN Support.

• Use native Microsoft MPIO DSM support with Windows Server 2008. Use either the
Server Manager or the command line interface (mpclaim CLI tool) to perform the
installation.
See the following web sites for information about using native Microsoft MPIO DSM:

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

3

Connecting Hosts

• To prevent Microsoft Windows 2003 hosts from displaying the Found New Hardware
Wizard when the storage system is discovered, install the SCSI Enclosure Services
driver available from DDN Support.

NOTE :

The SCSI Enclosure Services driver is required for Windows Server 2003.

3.2 Cabling Considerations

Common cabling configurations address hosts, controller enclosures, drive enclosures, and
switches. Cabling systems to enable use of the licensed AssuredRemote™ feature — to
replicate volumes — is yet another important cabling consideration. See 3.7 "Connecting

Two Storage Systems to Replicate Volumes" for more information.

Fibre Channel ports can connect to Fibre Channel hosts; or be used with AssuredRemote for
replication (licensed option).

3.3 Connecting the Enclosure to Hosts

A host identifies an external port to which the storage system is attached. Cable connections
vary depending on configuration. This section describes host interface protocols supported
by EF3015 controller enclosures, while showing a few common cable configurations.

EF3015 Setup Guide (Rev A)

17

Connecting Hosts

NOTE :

The EF3015 controllers use Unified LUN Presentation (ULP) — a controller
firmware feature enabling hosts to access mapped volumes via host ports — without
the need for internal or external switches.

3.3.1 FC Host Ports

The EF3015 controller enclosures use Fibre Channel (FC) interface protocol for host port
connection, featuring either one or two controller modules. Each controller module
provides two host ports configured with a Fibre Channel small form-factor pluggable (SFP
transceiver) connector, supporting data rates of up to 8 Gbps, with a 1.2 GHz processor and
2 GB cache.

The models referenced above support Fibre Channel Arbitrated Loop (FC-AL or “loop”)
topology by default. Connection mode can be set to loop or point-to-point. Loop protocol can
be used in a physical loop or in a direct connection between two devices. Point-to-point
protocol is used to connect to a fabric switch. The EF3015 controller enclosures can
alternatively be cabled to support replication via the FC host interface ports.

3.4 Connecting Direct Attach Configurations

The EF3015 supports up to four direct-connect server connections, two per controller
module. Connect appropriate cables from the server’s HBAs to the controller module’s host
ports as described below, and shown in Figure 7.

• To connect the EF3015 controller enclosure to a server HBA or switch — using the
controller’s FC host ports — select Fibre Channel cables supporting 2/4/8 Gb data rates,
that are compatible with the controller module‘s host port SFP connector. Such cables
are also used for connecting a local storage system to a remote storage system via a
switch, to facilitate use of the optional AssuredRemote replication feature.

• The table below maps SFP transceiver data rates to relative fiber optic cable
characteristics (i.e., cable length, multimode fiber type (MMF), and ISO/IEC optical
multimode cable performance standards). When transferring data through FC
connections, cable lengths should not exceed the lengths listed for each given fiber type
and performance code within the applicable data rate (2/4/8 Gb) class.
