Hitachi Lightning 9900™ User and Reference Guide 7
Table 1.1 Program Products and Service Offerings (continued)
Function Description See Section:
Resource Management:
HiCommand™ Enables users to manage the 9900 subsystem and perform functions (e.g., LUN
Manager, SANtinel) from virtually any location via the HiCommand™ Web
Client, command line interface (CLI), and/or third-party application.
3.7.14
LUN Manager Enables users to configure the 9900 fibre-channel ports for operational
environments (e.g., arbitrated-loop (FC-AL) and fabric topologies, host failover
support).
3.7.15
LU Size Expansion (LUSE) Enables open-system users to create expanded LUs which can be up to 36
times larger than standard fixed-size LUs.
3.7.16
Virtual LVI (VLVI)
Virtual LUN (VLUN)
Enables users to configure custom-size LVIs and LUs which are smaller than
standard-size devices.
3.7.17
FlashAccess (Flsh) Enables users to store specific high-usage data directly in cache memory to
provide virtually immediate data availability.
3.7.18
Cache Manager Enables users to perform FlashAccess operations from the S/390
®
host system.
FlashAccess allows you to place specific data in cache memory to enable
virtually immediate access to this data
3.7.19
Hitachi SANtinel
Hitachi SANtinel – S/390
®
Allows users to restrict host access to data on the Lightning 9900™ subsystem.
Open-system users can restrict host access to LUs based on the host’s World
Wide Name (WWN). S/390
®
mainframe users can restrict host access to LVIs
based on node IDs and logical partition (LPAR) numbers.
3.7.20
3.7.21
Prioritized Port Control (PPC) Allows open-system users to designate prioritized ports (e.g., for production
servers) and non-prioritized ports (e.g., for development servers) and set
thresholds and upper limits for the I/O activity of these ports.
3.7.22
Hitachi Parallel Access Volume
(HPAV)
Enables the S/390
®
host system to issue multiple I/O requests in parallel to
single LDEVs in the Lightning 9900™ subsystem. HPAV provides compatibility
with the IBM
®
Workload Manager (WLM) host software function and supports
both static and dynamic PAV functionality.
3.7.23
Dynamic Link Manager™ Provides automatic load balancing, path failover, and recovery capabilities in the
event of a path failure.
3.7.24
LDEV Guard Enables the assigning of access permissions (Read/Write, Read-Only, and
Protect) to logical volumes in a disk subsystem. 3390-3A, 3390-3B and 3390-3C
volumes can be used by both mainframe hosts and open-system hosts.
Note: Please check with your Hitachi Data Systems representative for the latest
feature availability.
MK-92RD072
Storage Utilities:
Hitachi CruiseControl Monitors subsystem and volume activity and performs automatic relocation of
volumes to optimize performance.
3.7.26
Hitachi Graph-Track™ (GT) Provides detailed information on the I/O activity and hardware performance of
the 9900 subsystem. Hitachi Graph-Track™ displays real-time and historical
data in graphical format, including I/O statistics, cache statistics, and front-end
and back-end microprocessor usage.
