Key enhancements include:

'We recently implemented HP-UX 11i v3 on HP Integrity servers in our SAP production environment. Version 3 gives us a rich set of management tools to tune our environment for outstanding performance and efficiency. The operating system's deployment and configuration features let our system administrators automate routine maintenance, simplify complex tasks and save time.'

– Hemant Dhamane, Assistant Manager, Information & Technology, Alkem Laboratories

OS control for additional energy savings: save up to 8% of processor power costs

HP-UX 11i v3 Green Active Processors raises the control to the operating system, enabling you manually or automatically to power down active processors to reduce energy consumption, for a saving of up to 8% on processor power costs.

HP-UX 11i v3 already enables powering down floating cells, I/O cards and idle processors. HP facilitates power planning with Capacity Advisor and a set of power calculators.

Serviceguard A.11.19: 83% faster failover, simpler management

Serviceguard A.11.19 reduces unplanned downtime by 83% with faster failover.

With SAP liveCache, SAP recovery after a failover takes less than two minutes.

Serviceguard A.11.19 eliminates planned downtime associated with cluster maintenance and configuration.

It delivers fully integrated advanced resource management to reduce custom scripting, avoid human error, and provide a fully supported environment.

Integrity Virtual Machine Online Guest Migration                                                                    

Integrity Virtual Machine (VM) Online Guest Migration enables a running VM, its operating system, and its applications to be moved to a different VM Host system without service interruption.

Enterprise Cluster Manager Toolkit: clustering made easier

Serviceguard Enterprise Cluster Manager Toolkit (ECMT) now includes toolkits for DB2, Sybase and MySQL at no charge, and accelerates integration of Oracle ASM into a cluster by 13%.

DRD: Update HP-UX 11i v3 online                                                        

Dynamic Root Disk Dynamic Root Disk (DRD) now enables online upgrades to HP-UX 11i v3 with only the reboot time left as planned downtime.

For a typical HP Integrity rx3600, that's a 50% reduction in downtime. This enhancement is just in time to save planned downtime, when you upgrade from older releases of HP-UX 11i v3 to Update 4!

MemFS doubles the performance of in-memory file system operations, vs. v2

Memory File System, new to v3, accelerates database and ERP operations by enabling them to be done in memory.

This new implementation is twice as fast as the v2 implementation, and easier to use in every way.

Logical Volume Manager

Logical Volume Manager reduces planned downtime, improves operations performance and simplifies updating L1 volume group layouts to the latest, most scalable L2 layout.
  • Make provisioning changes online to volumes when your requirements grow or shrink – no downtime boot required.
  • Improve performance by up to 88% in volume group scan and import operations.
  • Upgrade L1 volume group layouts in place to the highly scalable, modern L2 layout

MirrorDisk/UX

If you care enough to use RAID, you'll appreciate MirrorDisk/UX's increased protection through greater data and access redundancy.
  • The number of mirror copies increased from 3 to 6.
  • Concurrent clustered node access to mirrors increased from 2 to 16.
  • Reduce time to re-synch with improved Mirror Write Cache and parallel re-synch enhancements
  • Extended Distance (100 KM) shared clustered nodes increased from 2 to 4.

Bastille: 50% more items, more automation

>Enhanced Bastille offers 50% more system items that can be hardened to further reduce time and expertise required to secure your HP-UX 11i v2 and v3 systems, more automatically, helping you meet security benchmark standards more easily.

Disk Scrub: erase-in-place convenience

Disk Scrub delivers DoD-approved method of overwriting hard drives to ensure data is unrecoverable. When formatting a drive isn't enough, use Disk Scrub – implemented as a new option for the mediainit command – to more thoroughly sanitise the drive for re-use.

HP includes Disk Scrub for your convenience, compared to locating open source tools for overwriting drives.

Note: Disk Scrub is not the solution for you if your requirements include DoD or other tool certification, verification of data erasure, degaussing or physical destruction of a hard drive prior to disposal.

System Management Homepage (SMH)

HP SMH 3.0.0 for HP-UX 11i v2 and v3 simplifies SMH set-up and use. Enhancements include:
  • The new command smhassist which verifies that SMH-required software, port access and user and group IDs exist, and suggests corrective action if not.
  • GUI control for time-out values for waiting for requested data and for the SMH session itself.
  • SMH sessions now persist across SMH configuration changes.

Enhancements to SMH plug-ins expand management scope and simplify multi-system management:

  • In the file system tool: First-ever backup and recovery utility for incremental daily backups, for convenience with small servers

  • Network services configuration: New utility to list, add, modify and clear Ipv6 Neighbour Discovery Cache entries

  • Peripheral devices: Ability to enable, disable and run diagnostics on Fibre Channel adaptors

  • Distributed systems administration utilities (DSAU): Ability to configure consolidated logging for multiple clients, for a single system log on a single server, and a GUI-based wizard for synchronising files (e.g. /etc/psswd) across multiple clients

Mass Storage Stack – faster, cheaper, easier

HP-UX 11i is the first UNIX® operating system to solve a problem as old as UNIX: SAN port congestion. Maybe you've seen the symptom – 'QUEUE FULL' conditions during heavy I/O. Maybe you've experienced performance degradation, and addressed it with more storage devices.

HP-UX 11i v3 allows you to set queue depth for each LUN or LUN path, but most system administrators leave the queue depth at the default value (8), resulting in lower performance for some LUNS when others are not in use.

Update 4 moves queue depth to a higher scope, and automatically tunes the server resources to those on the target storage devices. With Update 4, you should see faster performance, fewer parameters to tune, fewer invoices for additional storage.
