About the Hitachi RAID Storage Systems
The Hitachi RAID storage systems offer a wide range of storage and data
services, including thin provisioning with Hitachi Dynamic Provisioning™
software, application-centric storage management and logical partitioning, and
simplified and unified data replication across heterogeneous storage systems.
These storage systems are an integral part of the Services-Oriented Storage
Solutions architecture from Hitachi Data Systems, providing the foundation for
matching application requirements to different classes of storage and
delivering critical services such as:
•
Business continuity services
•
Content management services (search, indexing)
•
Non-disruptive data migration
•
Volume management across heterogeneous storage arrays
•
Thin provisioning
•
Security services (immutability, logging, auditing, data shredding)
•
Data de-duplication
•
I/O load balancing
•
Data classification
•
File management services
The Hitachi RAID storage systems include the Virtual Storage Platform (VSP),
Universal Storage Platform V and VM (USP V/VM), and the TagmaStore
Universal Storage Platform and Network Storage Controller (USP/NSC). These
storage systems provide heterogeneous connectivity to support multiple
concurrent attachment to a variety of host operating systems (OS), including
VMware® as well as Windows®, UNIX®, Linux®, and mainframe servers,
enabling massive consolidation and storage aggregation across disparate
platforms. The storage systems can operate with multi-host applications and
host clusters, and are designed to handle very large databases as well as data
warehousing and data mining applications that store and retrieve terabytes of
data.
The Hitachi RAID storage systems are configured with OPEN-V logical units
(LUs) and are compatible with most fibre-channel (FC) host bus adapters
(HBAs). Users can perform additional LU configuration activities using the LUN
Manager, Virtual LVI/LUN (VLL), and LUN Expansion (LUSE) features provided
by the Storage Navigator software, which is the primary user interface for the
storage systems.
For more information about storage solutions and the Hitachi RAID storage
systems, please contact your Hitachi Data Systems account team.

Hardware Installation
Configuration Guide for VMware™ ESX Server Host Attachment
Table 2-1
Logical Device Types
Device Type
Description
OPEN-V Devices
OPEN-V logical units (LUs) are logical devices of variable sizes as defined by the
user.
LUSE Devices
(OPEN-V*n)
LUSE devices are LUs that are created by combining up to 36 LUs. The LUN
Expansion (LUSE) software on Storage Navigator enables you to configure these
devices. LUSE devices are designated as OPEN-x*n, where x is the LU type (e.g.,
OPEN-V) and n is the number of combined devices. For example, a LUSE device
created from 10 OPEN-V LUs is designated as an OPEN-V*10 device. This enables
the host to access the data stored on the storage system using fewer LU numbers.
VLL Devices
(OPEN-V VLL)
VLL devices are customized LUs that are configured using the Virtual LVI/LUN
software on Storage Navigator. The VLL devices are configured by “slicing” a single
LU into several smaller LUs that best fit your application needs to improve host
access to frequently used files. VLL devices are designated as OPEN-V-CVS
devices, where “CVS” stands for custom volume size.
VLL LUSE Devices
(OPEN-V*n VLL)
The VLL LUSE feature allows you to combine Virtual LVI/LUN devices (instead of
standard OPEN-V LUs) into LUSE devices. For example, a VLL LUSE device created
by using LUSE to combine 10 OPEN-V VLL (OPEN-V-CVS) volumes into a single
logical device is designated as an OPEN-V*10-CVS device.
OPEN-x Devices
The OPEN-x LUs (e.g., OPEN-3, OPEN-9) are logical devices of predefined sizes.
The Hitachi RAID storage system supports OPEN-3, OPEN-8, OPEN-9, OPEN-E, and
OPEN-L devices. For more information about these device types, contact your
Hitachi Data Systems account team.

Configuring the Hitachi RAID Storage System
Complete the following tasks before connecting the Hitachi RAID storage
system to your VMware server:
1. Use the LUN Manager software on Storage Navigator to set the host mode
and host mode options for the host groups on the fibre-channel ports.
2. Review the system option modes (SOMs) for your storage system model,
and ask your Hitachi Data Systems representative to set the applicable
system option modes on the service processor (SVP).
3. Use the LUN Manager software on Storage Navigator to set the
host-specific parameters and configure the fibre-channel ports.
4. Configure the fibre-channel HBAs connected to the storage system.
Setting the Host Mode
You can connect multiple server hosts of different platforms to a single port,
but you must group server hosts connected to the storage system by host
groups, which are segregated by platform. For example, if both VMware hosts
and Windows® hosts are connected to a single port, you must first create a
separate host group for each platform, and then register the hosts to the
corresponding host group. When you create a host group, you need to set the
host mode and host mode options for the group.
Use Storage Navigator to create host groups, register hosts in host groups,
and set host modes and host mode options. For the VSP storage system, see
the Provisioning Guide for Open Systems for instructions. For the USP V/VM
and USP/NSC storage systems, see the LUN Manager User’s Guide for
instructions.
For VSP and USP V/VM: Select one of the following host modes:
•
01 [VMware]
•
21 [VMware Extension]*
*Use host mode 21 if you think you will create LUSE volumes. If you think
you will create a LUSE volume using a volume to which an LU path has
already been defined, you must use host mode 21.
For TagmaStore USP/NSC: Use host mode 0A for VMware, even though
host mode 0A is displayed as 0A[NetWare].

Hitachi RAID Storage System Configuration
Configuration Guide for VMware™ ESX Server Host Attachment
Setting the Host Mode Options
When you create a host group, you need to set the host mode and host mode
options (HMOs) for the group. Table 3-1 lists the host mode options that apply
to VMware host attachment.
Note: There may be additional host mode options that can be set for VMware
operations. For a complete list of host mode options, see the Provisioning
Guide for Open Systems for VSP, and see the LUN Manager User’s Guide for
USP V/VM and USP/NSC.

Setting the System Option Modes
To provide greater flexibility and enable the Hitachi RAID storage system to be
tailored to unique customer operating requirements, additional operational
parameters called system option modes (SOMs) are available. At installation,
the SOMs are set to their default values. The SOMs are set on the service
processor (SVP) and can only be changed by the Hitachi Data Systems
representative.
To ensure that the appropriate SOMs are set:
1. Review the SOMs for your storage system model. The SOMs are described
in details in the User and Reference Guide for your storage system model:
–
Hitachi VSP User and Reference Guide, MK-90RD7042
–
Hitachi USP V/VM User and Reference Guide, MK-96RD635
–
Hitachi USP/NSC User and Reference Guide, MK-94RD231
2. Discuss the SOMs with your Hitachi Data Systems representative, and ask
the representative to set the SOMs that apply to your configuration and
environment.

Hitachi RAID Storage System Configuration
Configuration Guide for VMware™ ESX Server Host Attachment
Configuring the Fibre-Channel Ports
The LUN Manager software on Storage Navigator is used to configure the FC
ports. Table 3-2 explains the LUN Manager settings. Using LUN Manager,
select the appropriate settings for each FC port based on the device to which
the port is connected. Determine the topology parameters supported by the
device and port type, and set your topology accordingly. For details and
instructions, see the Provisioning Guide for Open Systems for VSP, and see the
LUN Manager Users Guide for USP V/VM and USP/NSC.
Port address. In fabric environments, the port addresses are assigned
automatically by fabric switch port number and are not controlled by the

Configuring the Fibre-Channel HBAs
Before connecting the Hitachi RAID storage system to the VMware system,
configure the fibre-channel HBAs to be connected to the Hitachi RAID storage
system. For information about supported HBAs, refer to the Hitachi Data
Systems interoperability site: http://www.hds.com/products/interoperability
Check the manufacturer’s documentation for your fibre-channel HBAs for these
options that are required to meet your operational requirements:
•
Queue depth, BIOS, target reset, and FC topology parameters.
•
Determine whether the BIOS must be disabled to prevent the system from
booting from the Hitachi RAID storage system.
To prepare for connecting the Hitachi RAID storage system, configure the
fibre-channel HBAs connected to the storage system. For information about
configuring your HBAs, refer to these sources:
•
Documentation that came with your HBA
•
HBA vendor’s website
•
Hitachi Data Systems interoperability site:
http://www.hds.com/products/interoperability
•
VMware Server Configuration Guide
The HBAs may require additional configuration. Refer to the user
documentation for your HBA to ensure that all options required for your
operational environment are set. After configuring the HBA, you may have to
reset the VMware server to have the change take effect before restarting the
VMware server.
Use the same settings and device parameters for all Hitachi RAID storage
systems. Then, after configuring the HBAs, reset the VMware ESX Server to
have the change take effect before booting to the VMware ESX Server.
The following subsections describe:

•
Setting the queue depth parameter
•
Configuring the BIOS of the HBAs for use with the Hitachi RAID storage
system.
Hitachi RAID Storage System Configuration
Configuration Guide for VMware™ ESX Server Host Attachment
Setting the Queue Depth Parameter
You may need to change the queue depth value on the server. If the number
is small, I/O performance can deteriorate and when this happens, the Hitachi
RAID storage system reports a queue full status (because the queue depth
exceeds an allowable limit). The system may not operate correctly when the
queue is full and a large value is set. Set an appropriate number according to
your configuration. If necessary, set a queue depth number for each server.
Refer to the documentation for your HBA before setting a value.
Guidelines for settings:
•
Queue depth: 32 commands per LU
•
Commands per port:
–
VSP: 2048
–
USP V/VM: 2048
–
TagmaStore USP/NSC: 1024
The following subsections provide sample procedures for setting queue depth
on QLogic and Emulex HBAs. For information about other HBAs, refer to the
documentation for your HBA or the HBA vendor’s website.
Setting the Queue Depth on QLogic HBAs
To set the queue depth parameter on QLogic HBAs:
1. Issue the following command to identify the HBA's driver name:
# vmkload_mode -l | grep qla
Sample output: qla2300_707_vmw
2. Issue the following command lines, with the following considerations:
Substitute the name output for <driver_name> parameter.
Substitute the queue depth value calculated for the "nn" parameter.
The last line reboots the server.
# esxcfg-module -s "ql2xmaxqdepth=nn" <driver_name>
# esxcfg-boot -b
# reboot
Hitachi RAID Storage System Configuration
Configuration Guide for VMware™ ESX Server Host Attachment

Hitachi RAID Storage System Configuration
Configuration Guide for VMware™ ESX Server Host Attachment
Connecting the Storage System to the VMware Server
After you have prepared the Hitachi RAID storage system (host modes, host
mode options, system option modes, fibre-channel ports) and configured the
HBAs, the Hitachi RAID storage system can be connected to the VMware
system. Some of these steps are performed by the Hitachi Data Systems
representative, while other steps are performed by the user.
Note: The Hitachi Data Systems representative must use the Maintenance
Manual during all installation activities. Follow all precautions and procedures
in the Maintenance Manual, and always check all specifications to ensure
proper installation and configuration.
To connect the Hitachi RAID storage system to the VMware Server host:
1. Verify the system installation. The Hitachi Data Systems representative
verifies the configuration and operational status of the Hitachi RAID storage
system fibre-channel ports, LDEVs, and paths.
2. Shut down and power off the VMware host. The user shuts down and
powers off the VMware host. The power must be off when the FC cables are
connected.
3. Connect the Hitachi RAID storage system to the VMware system.
The Hitachi Data Systems representative connects the fibre-channel cables
between the Hitachi RAID storage system and the VMware host or fabric
switch. Verify the ready status of the storage system and peripherals.
4. Power on and boot the VMware system. The user powers on and boots
the VMware system after the storage system has been connected:
a. Power on the VMware system display.
b. Power on all peripheral devices. The Hitachi RAID storage system must
be on, and the fibre-channel ports must be configured. If the
fibre-channel ports are configured after the VMware system is powered
on, the system may need to be restarted to recognize the new devices.
c. Confirm the ready status of all peripheral devices, including the Hitachi
RAID storage system.
d. Power on and boot the VMware system.
Hitachi RAID Storage System Configuration
Configuration Guide for VMware™ ESX Server Host Attachment
3-11
Storage Provisioning
The Hitachi LUN Manager software on Storage Navigator enables you to
configure and manage host groups, ports, and LUN security. Host groups must
be created to allow and control host access to LUNs. They are created per
VMware cluster or per ESX host on the fibre channel ports on each storage
cluster that the VMware cluster or the ESX hosts can access.
While host groups can be created with more than one WWN, it is
recommended that you create one host group for each HBA and name the host
group the same as the nickname for the HBA. Creating one host group per
HBA provides flexibility and is the only supported configuration when booting
hosts from a SAN.
If you are planning to use the the Hitachi Command Control Interface (CCI)
software to perform operations on the storage system, you will use LUN
Manager to set the command device for the Hitachi CCI software.
The LUN Expansion (LUSE) and Virtual LVI/LUN (VLL) software on Storage
Navigator enable you to configure, reconfigure, and customize the logical
devices on the Hitachi RAID storage system.
For information and instructions on these operations, see the applicable user
documents for your storage system model (see Referenced Documents).

Note 1: The availability of specific device types depends on the storage
system model and the level of microcode installed on the storage system.
Note 2: The command device (used for Command Control Interface
operations) is distinguished by -CM on the product name (e.g., OPEN-3-CM,
OPEN-3-CVS-CM). The product name for VLL devices is OPEN-x-CVS, where
CVS stands for custom volume size.
Note 3: This capacity is the maximum size that can be configured on the host.
The device capacity can sometimes be changed by the BIOS or host bus
adapter. Also, different capacities may be due to variations such as 1 MB =
10002 or 10242 bytes.
Note 4: The number of blocks for a VLL volume is calculated as follows:
# of blocks = (# of data cylinders) × (# of heads) × (# of sectors
per track)
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 2) × (15 heads) × (96
sectors per track) = 76320
Note 5: The number of data cylinders for a VLL volume is calculated as follows
(↑…↑ means that the value should be rounded up to the next integer):
•
Number of data cylinders for OPEN-x VLL volume (except for OPEN-V) =
# of cylinders = ↑ (capacity (MB) × 1024/720 ↑
Example: For OPEN-3 VLL volume with capacity = 37 MB:
# of cylinders = ↑37 × 1024/720↑ = ↑52.62↑ = 53 cylinders

•
Number of data cylinders for an OPEN-V VLL volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 16/15 ↑
Example: For OPEN-V VLL volume with capacity = 50 MB:
# of cylinders = ↑50 × 16/15↑ = ↑53.33↑ = 54 cylinders
•
Number of data cylinders for a VLL LUSE volume (except for OPEN-V) =
# of cylinders = ↑ (capacity (MB) × 1024/720 ↑ × n
Example: For OPEN-3 VLL LUSE volume with capacity = 37 MB and n = 4:
# of cylinders = ↑37 × 1024/720↑ × 4 = ↑52.62↑ × 4 = 53 × 4 =
212
•
Number of data cylinders for an OPEN-V VLL LUSE volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 16/15 ↑ × n
Example: For OPEN-V VLL LUSE volume with capacity = 50 MB and n = 4:
# of cylinders = ↑50 × 16/15↑ × 4 = ↑53.33↑× 4 = 54 × 4 = 216
Note 6: The size of an OPEN-x VLL volume is specified by capacity in MB, not
number of cylinders. The size of an OPEN-V VLL volume can be specified by
capacity in MB or number of cylinders. The user specifies the volume size
using the Virtual LVI/LUN software.

B-1
VMware ESX Server and VirtualCenter Compatibility
VMware recommends that you install VirtualCenter with the ESX Server
software. VirtualCenter lets you provision virtual machines and monitor
performance of physical servers and virtual machines, monitor performance
and utilization of physical servers and the virtual machines they are running,
and export VirtualCenter data to HTML and Excel formats for integration with
other reporting tools.
It is vital that you make sure that your ESX server and VirtualCenter versions
are compatible. For information about the VirtualCenter versions compatible
with the VMware ESX server versions, please refer to your VMware Release
Notes and the VMware website at www.vmware.com.

Installing and Configuring VMware
For your VMware installation to succeed, it is important to verify that your
server, I/O, storage, guest operating system, management agent, and backup
software are all compatible before you install and configure VMware.
The following sections identify the VMware documentation to consult for
information about installing and configuring VMware ESX Server. These
documents also contain compatibility information.
Installing and Configuring VMware ESX Server
Refer to the VMware documentation when installing and configuring VMware
ESX Server. Be sure to follow the configuration steps for licensing, networking,
and security.
Upgrading an ESX Server and VirtualCenter Environment
Refer to the VMware documentation when upgrading an ESX Server and
VirtualCenter environment.

Creating and Managing VMware Infrastructure
Components
After you install VMware ESX Server on a host, you have completed the
installation of all the major components of the VMware Infrastructure. You can
then perform the following steps to manage your VMware infrastructure
components.
B-4
•
Use the VI client to manage your ESX Server hosts either as a group
through VirtualCenter or individually by connecting directly to the host.
•
Set up a datacenter to bring one or more ESX Server hosts under
VirtualCenter management, create virtual machines, and determine how
you want to organize virtual machines and manage resources.
•
Create a Virtual Machine manually, from templates, or by cloning
existing virtual machines.
•
Configure permissions and roles for users to allocate access to
VirtualCenter, its administrative functions, and its resources.
•
Use resource pools to partition available CPU and memory resources
hierarchically.
•
Configure network connections to ensure that virtual machine traffic
does not share a network adapter with the service console for security
purposes.
•
Install a guest operating system in a virtual machine.
•
Manage virtual machines to learn how to power them on and off.
•
Monitor the status of your virtual infrastructure using tasks and
events.
•
Schedule automated tasks to perform actions at designated times.
•
Configure alarm notification messages to be sent when selected
events occur to or on hosts or virtual machines.
