Hitachi Universal Storage Platform V/VM Configuration Guide for SGI®IRIX® Host Attachment
About the Hitachi Universal Storage Platform V
The USP V from Hitachi Data Systems is a comprehensive and fully integrated
universal storage services platform that builds on the proven technical
superiority and features of Hitachi Data Systems’ USP disk arrays. As an
evolution of the USP solutions, the USP V combines refinements to existing
technology with new functionality to deliver higher system performance,
increased scalability, and greater levels of availability.
The USP V provides heterogeneous data replication and copy services between
any platform at any distance, with higher performance, increased data
protection, and more efficient use of network bandwidth than previously
available. The result is reduced costs, simplified management, and improved
data protection and disaster recovery capability. The following list summarizes
the USP V’s key benefits and the advantages they deliver.
•Massive multi-protocol consolidation. The USP V provides an
integrated platform for consolidating and centralizing data, while providing
access to hundreds or thousands of servers with differing connectivity
requirements. USP V support for fibre channel, ESCON, and FICON -
coupled with logical partitioning, virtual storage ports, and centralized
management with HiCommand Software - provides the most
comprehensive and flexible platform for massive consolidation of storage
systems with multi-protocol requirements, while delivering the software
tools to monitor, manage, and optimize the environment to ensure
application quality of service.
•Simplified storage management. Embedded second-generation
virtualization features allow multiple storage systems to be aggregated (or
consolidated) into a single storage pool to reduce storage management
complexities and costs. Customers can now manage the entire
infrastructure from a single pane of glass, or have multiple storage
administrators manage particular sets of storage resources.
•Tiered storage foundation for data lifecycle management. The USP V
reduces costs and improves efficiency by allowing heterogeneous tiered
storage to be managed from a single console and moved non-disruptively
between storage tiers as the value of the data or the usage model changes.
With the USP V, a tiered storage infrastructure can be built internally or in
combination with externally attached storage, including FICON for IBM
z/OS mainframe operating systems.
•Investment protection. USP V customers can enjoy a storage technology
refresh while protecting their current storage system investment by
attaching their legacy storage to the USP V externally and using powerful
software tools such as unique virtualization, storage partitioning, and
universal replication with their legacy storage. Customers can non-
disruptively migrate their data to the USP V, or any other platform within
the USP V’s external storage pool (including FICON for IBM z/OS
customers), at the appropriate time.

Introduction 1-3
Hitachi Universal Storage Platform V/VM Configuration Guide for SGI®IRIX® Host Attachment
•Reduced Total Cost of Ownership (TCO) with improved data
availability. A new thin provisioning software feature improves data
availability while reducing storage TCO by allowing customers to allocate
“virtual” disk storage based on their anticipated future needs, with less
physical disk than initially required. Additional physical disks can be
purchased later and installed transparently without interrupting application
services.
•Increased Return on Investment (ROI). The USP V increases ROI by
providing investment protection and longer life for legacy storage, superior
storage and server utilization, improved application quality of service,
lower software licenses/costs, and simplified and centralized storage
management.
•Reduced mainframe storage costs. The USP V lets mainframe
customers exploit SATA storage either internal to the USP V or externally
attached to improve data protection, cost-effectively store larger amounts
DFSMS Migration Level 1 data and offload costly DFSMS mainframe
processing cycles, or deploy a long-term and secure data archive solution
for regulatory compliance. The USP V’s virtual private storage machines are
the ideal compliment to mainframe LPARs for providing workload isolation
and optimum quality of service.
•Application data mobility solutions. The USP V is complemented by a
rich suite of software solutions for managing storage across an entire
heterogeneous storage pool:
–HiCommand Tiered Storage Manager - lets customers continually adjust
their storage infrastructure to meet their changing business needs.
–HiCommand Tuning Manager and HiCommand Device Manager – let
customers continually monitor and forecast their storage infrastructure
needs.
–Hitachi ShadowImage In-System Replication and Hitachi Universal
Replication - deliver proven scalable data-protection for meeting the
most stringent business continuance and compliance requirements of
the world’s largest financial institutions.
–Hitachi Universal Replication and Hitachi ShadowImage now support
more volumes and replication pairs than before. Performance has also
been improved, with support added for more consistency groups spread
across four USP V systems located at each site within a 2- or 3-
datacenter configuration.
Note: The availability of the Hitachi USP V features and functions depends on
the level of microcode installed.

1-4 Introduction
Hitachi Universal Storage Platform V/VM Configuration Guide for SGI®IRIX® Host Attachment
Device Types
Table 1-1 describes the types of logical devices (volumes) that can be installed
and configured for operation with the USPV on an SGI IRIX operating system.
Table 1-2 lists the specifications for devices supported by the USP V. For
information about configuring devices other than OPEN+V, contact your
Hitachi Data Systems representative.
Note: Logical devices are defined to the host as SCSI disk devices, even
though the interface is fibre channel.
Table 1-1 Types of Logical Devices Supported by the USP V
Device Type Description
OPEN-x Devices OPEN-xlogical units (LUs) (e.g., OPEN-3, OPEN-9) are disk devices of
predefined sizes. USP V supports OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-
L, and OPEN-V devices (OPEN-V is a VLL-based volume and has no standard
size). For the latest information about supported LU types, please contact
your Hitachi Data Systems account team.
LUSE Devices (OPEN-
x*n)
LUSE devices are combined LUs that can be from 2 to 36 times larger than
standard OPEN-x LUs. Using LUN Expansion (LUSE) remote console software,
you can configure these custom-size devices. LUSE devices are designated
as OPEN-x*n, where x is the LU type (e.g., OPEN-9*n) and 2< n < 36). For
example, a LUSE device created from 10 OPEN-3 LUs is designated as an
OPEN-3*10 disk device. This lets the host combine logical devices and
access the data stored on the USP V using fewer LU numbers. For more
information about LUSE, see the Hitachi Universal Storage Platform V LUN
Expansion (LUSE) and Virtual LVI/LUN User’s Guide (MK-96RD630).
VLL Devices (OPEN-x
VLL)
VLL devices are custom-size LUs that are smaller than standard OPEN-xLUs.
Using Virtual LVI/LUN remote console software, you can configure VLL
devices by “slicing” a single LU into several smaller LUs that best fit your
application needs to improve host access to frequently used files. For more
information about the Virtual LVI/LUN feature, see the Hitachi Universal
Storage Platform V LUN Expansion (LUSE) and Virtual LVI/LUN User’s Guide
(MK-96RD630). The product name for the OPEN-xVLL devices is OPEN-x-
CVS (CVS stands for custom volume size). The OPEN-L LU type does not
support Virtual LVI/LUN.
VLL LUSE Devices
(OPEN-x*n VLL)
VLL LUSE devices combine Virtual LVI/LUN devices (instead of standard
OPEN-xLUs) into LUSE devices. Use the Virtual LVI/LUN feature to create
custom-size devices, then use the LUSE feature to combine the VLL devices.
You can combine from 2 to 36 VLL devices into one VLL LUSE device. For
example, an OPEN-3 LUSE volume created from a0 OPEN-3 VLL volumes is
designated as an OPEN-3*10 VLL device (product name OPEN-3*10-CVS).

Introduction 1-5
Hitachi Universal Storage Platform V/VM Configuration Guide for SGI®IRIX® Host Attachment
Device Type Description
FX Devices (3390-
3A/B/C, OPEN-x-FXoto)
Using USP V’s Cross-OS File Exchange (FX) feature, you can share data
across mainframe, UNIX, and PC server platforms using special
multiplatform volumes. The VLL feature can be applied to FX devices for
maximum flexibility in volume size. For more information about FX, see the
Hitachi Cross-OS File Exchange User’s Guide (MK-96RD647), or contact your
Hitachi Data Systems account team.
FX devices are not SCSI disk devices, and must be installed and accessed as
raw devices. UNIX/PC server hosts must use FX to access the FX devices as
raw devices (no file system, no mount operation).
The 3390-3B devices are write-protected from UNIX/PC server access. The
USP V rejects all UNIX/PC server write operations (including fibre-channel
adapters) for 3390-3B devices.
Multiplatform devices are not write-protected for UNIX/PC server access. Do
not execute any write operation by the fibre-channel adapters on these
devices. Do not create a partition or file system on these devices. This will
overwrite any data on the FX device and prevent the FX software from
accessing the device.

Table 1-2 USP V Device Specifications (continued)
Note 1: The availability of a specific USP V device type depends on the level of
microcode installed on the USP V system.
Note 2: The category of a device (SCSI disk or FX) determines its volume
usage. Table 1-3 shows the volume usage for SCSI disk devices and FX
devices. The SCSI disk devices (OPEN-x, VLL, LUSE, VLL LUSE) are usually
formatted with file systems for SGI IRIX operations. The FX devices (3390-
3A/B/C, OPEN-x-FXoto) must be installed as raw devices and can only
accessed using FX. Do not create a partition or file system on any device used
for FX operations.

(The number of sectors per track is 128 for OPEN-V and 96 for the other
emulation types.)
Example: For an OPEN-3 VLL volume with capacity = 37 MB:
# of blocks = (53 cylinders – see Note 3) ×(15 heads) ×(96 sectors
per track) = 76320
