-- SANworks Management Appliance Rules with Enterprise
-- SAN Fabric Zoning Rules with Enterprise
-- Specific Operating System Rules with Enterprise
-- Heterogeneous Platform HSV110-based Storage System Maximums
Intended Audience
This document is intended for customers who purchased the StorageWorks SAN by Compaq
Enterprise Virtual Array and who wish to incorporate that storage into a heterogeneous open SAN.
Additional documentation, including white papers and best practices documents, are available via the
Compaq website at:
http://www.compaq.com.
Controllers and Storage Systems Terminology
HSV110 controllers are used in Enterprise Storage Systems that comprise Enterprise Virtual Arrays.
The HSG60 and HSG80 controllers are used in these storage systems:
MA 6 0 0 0
RA/MA8000
ESA/EMA12000
EMA16000
In this document, Host Bus Adapter (HBA) is equivalent to Fibre Channel Adapter (FCA) or Fibre
Channel Host Bus Adapter (FC HBA).
In HSG-based storage systems, Selective Storage Presentation (SSP) is used to control LUN access by
host type. In HSV-based storage systems, LUN Presentation is used to control access by host type.

SAN Configuration Rules with Enterprise Virtual Arrays
SAN Configuration Rules with Enterprise Virtual Arrays
This section presents updates to Chapter 3 and Chapter 4 of the Heterogeneous Open SAN Design
Reference Guide, 2nd Edition, (SAN Design Guide) that have changes specific to Enterprise Virtual
Arrays. Please see the SAN Design Guide for a more complete discussion of SAN fabric rules.
General HSV110 Configuration Rules
1. The supported platforms and operating systems are listed in Table 1.
2. The HSV110 controller is supported in all Compaq supported SAN Fabric topology configurations
noted in the SAN Design Guide or the platform application notes. The HSV110 is compatible in
SANs using SAN Switch 8/16, 8/16-EL, and SAN Switch Integrated 32/64 model switches.
3. Any mix of servers (clustered and standalone) and storage systems is allowed that satisfies the
maximums given in Table 2 and in the platform-specific release notes and documentation.
4. Refer to the SAN Fabric Zoning Rules with Enterprise section for information related to mixing
platforms on a single shared storage system.
5. The HSV110 controller supports cross-cable and the straight-cable high availability cabling
schemes. See Figure 41 and Figure 42 in the SAN Design Guide for cabling diagrams.
6. Supports Multiple-Bus Failover mode only. Multiple-Bus failover requires operating system or
separate multi-path driver functionality.
7. SSP - LUN level masking:
Use storage system LUN Presentation to enable/disable LUN access to specific hosts.
NOTE: Shared access between different servers to the same storage unit (LUN) requires specific application
software (i.e., MSCS) to ensure proper data preservation.
8. All host table entries must have the proper operating system type parameter set based on platform
type accessing the assigned LUNs. Refer to Table 1.
SANworks Management Appliance Rules with Enterprise
The SANworks Management Appliance (SWMA) manages Enterprise Virtual Arrays with the
HSV Element Manager.
1. A SAN Appliance is required to manage Enterprise Virtual Arrays. The HSV Element Manager
may manage up to 16 HSV controller pairs per appliance.
2. One SAN Appliance is required for each fabric in multiple fabric SANs.
3. Multiple appliances per fabric are allowed as long as only one appliance is accessing a controller
pair at a time. Zoning is required.
4. A license key is required for each Enterprise Virtual Array managed by the SWMA. Additional
licenses are required to take advantage of value added software functionality.
5. The Element Managers for HSG and for HSV controllers can not coexist on the same appliance.
4 Addendum - Heterogeneous Open SAN Design Reference Guide for Enterprise Virtual Array
SAN Configuration Rules with Enterprise Virtual Arrays
SAN Fabric Zoning Rules with Enterprise
Zoning must be used with Enterprise Virtual Arrays.
Each SWMA with the Element Manager for HSV (HSV SWMA) and the HSV controllers it
manages must be in a unique HSV management zone
For SANs with both HSV and HSG based storage:
-- Each SWMA with the Element Manager for HSG (HSG SWMA) and the HSG controllers it
manages must be in a unique HSG management zone
An HSG management zone must not overlap with an HSV management zone
-- HSG and HSV controllers can coexist in zones with servers but not with each others SWMAs
TRU64 UNIX and Windows NT/2000 servers must be in separate zones
For SANs with more than 1024 HBAs, an HSV controller must be zoned so that it can see no more
than 1024 HBAs. It may be necessary to add a zone to a SAN to satisfy the 1024 HBA limit.
Specific Operating System Rules with Enterprise
Table 1 summarizes the rules for configuring each supported hardware platform or operating system
with an Enterprise Storage System. Table 1 lists the platforms, HBAs, SANworks Secure Path version,
and the preferred method of storage attachment for each platform type. The sections following the
table describe additional rules not listed in the table.

Heterogeneous Platform HSV110-based
Storage System Maximums
Table 2 lists the maximum connections supported by HSV110 controllers. In addition, Table 2 lists the
maximum supported storage limits for each hardware platform or operating system. The maximums
shown here are for access to an Enterprise Storage System with dual redundant HSV110 controllers. If
the connection requirements for the number of servers in a particular SAN exceed the maximums, then
deploy multiple storage systems within the SAN.
Maximum of 1024 Host Bus Adapters (HBA)
Maximum of 256 LUNs
Maximum of 256 Hosts: A host is defined as one or more HBAs
The # of LUNs times the # of Hosts must not exceed 8192
-- Example: 64 LUNs on an Enterprise Storage System gives a maximum of 128 hosts that may
access that storage system
Table 2: Platform Storage Maximums - Enterprise Virtual Arrays
Host Bus Active Controller
LUNs per
Adapters per Ports (Targets) per
Platform or Operating System HBA Target
Server HBA
See Reference Notes 1 2 3
Compaq OpenVMS 7.2-1H1, 7.3 4 128 128
Tru64 UNIX 5.1, 5.1A 64 128 255
Microsoft Windows NT 4.0 SP6a 4 2/4 8/64
Windows 2000 (SP1 & SP2)
Sun Solaris 2.7, 2.8 16 2/4 128
Reference Notes
1. The maximum number of HBAs supported per server is dependent on the specific server model.
2. For Tru64 and OpenVMS this column typically represents the total number of active controller
ports per HBA when accessing all ports of a storage system or ports on multiple storage systems.
For all other platforms, this column typically represents 2 ports per storage system, or a total of 4
ports across 2 storage systems. Use of zoning may be required to limit the number of active targets
presented to each HBA to the maximums stated for each platform in this column.
3. For Microsoft Windows, supports 8 LUNs per HBA target with the Large LUN feature disabled
and 64 LUNs per HBA target with the Large LUN feature enabled.
