Storage System Overview
Storage System Overview
The BlueArc Storage System is a highly scalable and modular Network Attached Storage (NAS)
server with multi-gigabit throughput from network to disk.
The Titan SiliconServer has a patented architecture structured around bi-directional data
pipelines and a hardware-based file system. This allows the storage capacity to scale to 256
Terabytes, and sustain higher access loads without compromising performance. The storage
system can be configured as a single server or as a dual-server, high-availability cluster.
Titan supports BlueArc’s Multi-Tiered Storage (MTS), which can simultaneously connect
multiple diverse storage subsystems behind a single server unit (or cluster). Using MTS, Titan
can be customized to match the storage requirements of your applications. In this way, Titan
provides a solution that can meet your performance and scaling goals.
The BlueArc Storage System consists of the following elements:
❑The Titan SiliconServer. The SiliconServer technology is the core of the BlueArc
Storage System.
❑Enterprise Virtual Servers (EVS). The EVS are the file serving entities of the Titan
SiliconServer.
❑The Storage Subsystem. The storage subsystem consists of devices that store the
data managed by the Titan SiliconServer.
❑The System Management Unit (SMU). The SMU provides server administration
and monitoring tools. In addition, it supports clustering, data migration, and
replication.
❑The Private Management Network. The management network consists of
auxiliary devices required for operation of the BlueArc Storage System, such as
RAID storage subsystems, FC switches, and Uninterruptible Power Supply (UPS)
units.

The BlueArc Storage System
2Titan SiliconServer
The Titan SiliconServer
Titan is a high-performance, enterprise-class Network Attached Storage (NAS) server, which
services file access requests issued by network clients through Gigabit Ethernet. Titan satisfies
these requests by reading and writing data located on one or more storage devices, connected
through two or four Fibre Channel (FC) links. The storage system can be configured with a
single Titan SiliconServer or with multiple servers clustered together, sharing the same storage
devices.
Titan can be configured as an Active/Active (A/A) cluster, so network requests can be
distributed between two Cluster Nodes. Should a Cluster Node fail, its file services and server
administration functions are transferred to the other server.
The Titan SiliconServer chassis is 4U (7”) high, 48.3 cm (19”) rack mountable and a maximum
of 63.5 cm (25”) deep, excluding the fascia. It consists of a passive backplane (that is not
removable), three hot swappable fan trays and two hot swappable redundant power supplies.
The front panel shows system status through two LEDs (a green power LED and an amber fault
LED). The only Field Replaceable Units (FRUs) accessible from the front of the Titan
SiliconServer chassis are its cooling fans.
The unit is serviced from its rear panel, which includes additional status LEDs, connectors
(power, Ethernet, Fibre Channel, RS-232), and FRUs, such as the power supplies and server
modules. See the Titan SiliconServer Hardware Guide for more information on the Titan
SiliconServer hardware.

Storage System Overview
System Administration Manual 3
Enterprise Virtual Servers
All file services are provided by logical server entities referred to as Enterprise Virtual Servers
(EVS). A Titan SiliconServer or High Availability (HA) cluster supports up to eight EVS. Each
EVS is assigned unique network settings and storage resources. In a HA cluster, EVS are
automatically migrated between servers when faults occur to ensure maximum availability.
When multiple servers or clusters are configured with a shared storage pool, they are referred to
as a Server Farm. EVS can be manually migrated between servers in a Server Farm based on
performance and availability requirements.
The Storage Subsystem
The storage subsystem consists of storage devices and the Fibre Channel (FC) infrastructure
(such as FC switches and cables) used to connect these devices to Titan.
Titan supports BlueArc’s Multi-Tiered Storage (MTS), which can simultaneously connect
multiple diverse storage subsystems behind a single server or cluster.
MTS supports 4-tiers of disk based storage subsystems with different disk technologies and
performance characteristics. A fifth tier is used for FC or Ethernet attached Tape Library
Systems (TLS).
MTS usage can be optimized by using Data Migrator with Titan. With Data Migrator, routinely
accessed data can be retained on primary storage, while older data can be migrated to cost-

efficient secondary storage. Titan can monitor a file's size, type, duration of inactivity, access
history, etc., and migrate the files based on pre-defined rules that are triggered by any of the
mentioned criteria reaching a specific threshold. Migrations from primary to secondary storage
are handled as automated background tasks with minimal impact on server performance. To
the client workstation, it is indistinguishable whether the file’s contents have been migrated or
still remain on primary storage. Refer to the Data Migrator section for more detailed
information.
The System Management Unit (SMU)
Titan is managed from the System Management Unit (SMU) through its Web Manager interface.
The SMU also supports data replication and data migration and acts as the Quorum Device in a
Titan cluster. Although the SMU is an integral component of the BlueArc Storage System, it is
not involved in any data movement between the network client and Titan. All network clients
communicate directly with the Titan SiliconServer.
The Private Management Network
Titan operates in conjunction with a number of auxiliary devices such as RAID storage
subsystems, Fibre Channel switches, and UPS units. Most of these devices are managed
through Ethernet.
In order to minimize the impact on the enterprise network, Titan’s physical management

structure is divided into two discrete components:
❑A public data network (i.e. the enterprise network). The public management interface
from the BlueArc Storage System perspective consists of the first Ethernet port on the SMU
(the public Ethernet interface). In addition, management access can be enabled on
individual Gigabit Ethernet (GE) interfaces on Titan.
❑A private (sideband) management network. The private management network is a small
network used to connect Titan’s auxiliary devices and is isolated from the main network
through the SMU using Network Address Translation (NAT) technology. It consists of the
private management interface of the SMU, the 10/100 Mbps Ethernet management interface
on the server, and all the Ethernet managed devices that comprise the Titan Storage
Subsystem.
The private management network manages the storage subsystem, including auxiliary devices.
Devices on this network are only accessible from the public (data) network through the SMU,
which provides NAT, NTP, and email relay services. The SMU has two 10/100/1000 Mbps
Ethernet interfaces. The first interface (eth0) connects to the public (data) network, while the
second interface (eth1) resides on the private management network.
The diagram below shows how NAT isolates the private management network. The example
shows a device with the IP address 192.0.2.13:80 accessible through HTTP, and a second
device with IP address 192.0.2.14:443 accessible through HTTPS. These devices appear on the
enterprise network as 10.1.1.13:28013 and 10.1.1.13:28014.

Titan SiliconServer Initial Setup
The BlueArc Storage System is normally installed and pre-configured by BlueArc Global
Services.
Follow these steps to configure Titan:
1. Configure the SMU through its serial interface. When the SMU is first installed, the
following settings will need to be configured:
❑A server (or host) name. This is the name by which the SMU is identified on the
network.
❑An IP address and subnet mask. These are used to access the SMU.
❑A gateway IP address.
❑A DNS domain name.
❑Passwords for the root and manager accounts (default password is bluearc).
2. Perform the initial configuration of the Titan SiliconServer using the serial interface.
When Titan is first installed, it requires the following configuration settings:
❑An admin name. This is the server name. It should be unique as it will be used
to identify this specific server.
❑An administrative IP address and subnet mask. These are assigned to the 10/
100 management port, which is typically connected to the private management
network.
Note: The subnet mask should be the same as that used for the private
management network on the SMU (i.e. 255.255.255.0), and the IP address
should correspond to that network (i.e. 192.0.2.x).
❑A file serving IP address and subnet mask. These are assigned to the first
Gigabit Ethernet (GE) interface on the server. Once the initial configuration has
been completed, additional GE ports can be aggregated together to share these
settings, and further IP addresses can be assigned.
Tip: These settings should NOT correspond to the private management
network.
❑The IP address of the default gateway.
Completing the setup
1. Complete the setup of the SMU by running the SMU Setup Wizard.
2. Add Titan to the Managed Servers List in the SMU. Use the default administration
account with user name supervisor and password supervisor.

3. Enter License Key(s) for the server.
4. Run the SiliconServer Setup Wizard.
5. Complete Titan setup:
❑Network interface
❑Storage management
❑File services
❑Data protection
6. Optionally, configure Titan as part of a high availability cluster.
Managing the Titan SiliconServer
Titan and its storage subsystem is managed through Web Manager, a Web-based
administration tool. This tool allows most administrative tasks to be performed from any client
on the network using a suitable Web browser (Microsoft Internet Explorer 6.0 or later, or Firefox
1.0.4, or later). Web Manager can be configured to support multiple Titan SiliconServers.
As an alternative to the Web Manager, use the Command Line Interface (CLI), which is
documented in the Command Line Reference Guide.
Using Web Manager
The Web Manager is used to set up, operate, and monitor Titan and its storage subsystem. Web
Manager can be configured to support multiple Titan SiliconServers. However, only one server
can be managed at a time. This is referred to as the currently managed server.
Tip: Use the drop-down page in the Server Status console to select a
different server from the managed servers list.
The Web Manager’s home page shows the Server Status Console, the top-level page, and
shortcuts to commonly used functions.

Starting Web Manager
1. Open a Web browser.
2. In the Address or Location field, type the https:// prefix, followed by the name (or IP
address) assigned to the SMU. For example:
https://10.1.6.104/
3. Click ENTER.
4. When the login page appears, type the user name and password. Note that user names
and passwords are case-sensitive and that there is a default user account with the user
name admin and password bluearc.
Note: BlueArc recommends that this password be changed as soon as
possible.
Once the login procedure is completed, the Web Manager home page is displayed.
