Before you upgrade your HP-UX 11i environment, you want to know why it’s worth the time and effort. HP-UX 11i v3 exceeds the prior release’s advantages in several substantial ways that combine to drive up your ROI when you upgrade. If you’re still running v1 or v2, see what you’re missing! Find the quantified benefits below of upgrading, and the technical advancements that explain why. |
First, if your HP-UX system is on support, you can upgrade for no additional cost. Upgrading to v3 gets you the latest OE bundles: you gain up to 81% incremental software value. Plus, you can reduce software support costs in two ways—lower OE support prices, and eliminating support for stand-alone software if it’s bundled in the new v3 OEs. That’s in the single-system upgrade case: if you consolidate multiple older systems into fewer new systems, your advantages multiply.
Next, HP-UX 11i v3 functionality is enhanced in ways that drive down costs, while increasing productivity for end users, system administrators and software developers. |
- HP Integrity servers running v3 require 68% less time to manage than HP 9000 servers running v1/v2
- HP-UX 11i customers who upgraded to v3 reported an average performance increase of 29%
- Consolidating to HP Integrity v3 can cut energy usage by more than 50%
- Upgrading to v3 on Integrity reduces unplanned downtime

The benefits quantified above reflect users’ experience with early releases of v3, which first shipped in February ’07. To keep your systems running at their best, HP recommends updating to the latest v3 release. HP releases bundled updates about every six months.
Everything here is what HP has engineered into HP-UX 11i v3 that is not available on v2 or v1. This isn’t everything that’s hot in HP-UX 11i v3.
HP engineers a great many enhancements that benefit v2 customers, even though we released our final functional update to v2 in 2007. Instant capacity, single-pane-of-glass management with SIM and SMH, all things security, to name a few, are key HP-UX 11i benefits but are generally equivalent across HP-UX 11i releases.

Cost savings: simply spend less |
|
Performance |
|
HP-UX 11i v3 is faster than v2. And v2 set records for best results across the range of workloads tested in industry-standard benchmarks, now trumped by v3 benchmarks!
On average, v3 delivers 30% increase in application performance compared to v2—but customers report even higher benefits! That’s due to kernel optimization: With v3, HP optimized the HP-UX 11i kernel for HP Integrity servers’ Itanium processor architecture. The optimization benefits different applications differently: test your workload on an HP-UX 11i v3 in an HP Solution Center near you!
Memory File System on HP-UX 11i v3 is a new implementation that is twice as fast as the v2 MemFS, accelerating database and ERP performance through operations performance on data in memory, versus on disk.
Mass Storage Stack accelerates access to data on disk, with native multi-pathing and load balancing, as well as by eliminating SAN port congestion by increasing the port queue depth. (By the way, you can buy fewer disks when you get more performance from existing ones.)

Availability: driving down planned and unplanned downtime |
|
- Self-healing—where HP-UX 11i v3 fixes problems so you don’t have to—applies in v3 to failed I/O paths and devices and PCI errors.
- Dynamic nPars—enhancing our electrically isolated hard partitions—enables system administrators to reconfigure nPars without rebooting.
- PCI online deletion eliminates reboots associated with those configuration changes.
- HP presses on to make HP-UX 11i system tunables dynamic, eliminating the need to reboot when administrators change settings. Of the total, 73% of the tunables are now dynamic, up from 50% with v2 and 15% with v1.
- HP-UX Swapoff enables the removal of disks from a running system, eliminating another reboot.
- Logical Volume Manager (LVM) supports online provisioning changes. In the event of a Serviceguard cluster failover, data re-synch is much faster because we re-synch in parallel in v3, and implemented Mirror Write Cache to reduce the amount of data to be re-synched.
- Dynamic Root Disk enables online upgrades within HP-UX 11i v3 (e.g. Update 3 to Update 4), leaving only the reboot time left as downtime. For an HP Integrity rx3600 server, that’s a downtime reduction of about 50%.
- Preventive measures—when you care enough to cluster and use RAID, you care about increased redundancy. The number of mirrored copies of data is up from 3 to 6, and the number of cluster nodes that can concurrently access mirrored data is increased from 2 to 16
|
Simplified management: driving down the time and effort |
|
- Power management comes with HP-UX 11i v3, with controls to reduce energy costs from active and idle processors, I/O cards, and entire cells.
- Mass Storage Stack simplifies storage management with SAN device auto-detection and configuration. HP-UX 11i v3 also ships with an ‘erase-in-place’ disk sanitizer for convenient DoD-compliant hard drive erasure to render data unrecoverable, and leave the drive ready for re-use.
- Locality-optimized Resource Alignment (LORA) for cell-based servers automatically and continually aligns CPU, NUMA memory and applications to minimize latency and optimize performance.
- Tune-N-Tools is a run-once script that assigns values to HP-UX 11i v3 tunables, tested to optimize a system for typical UNIX workloads, like databases and ERP applications. LORA and Tune-n-Tools get you pretty close to full system performance potential, without the hand-tuning (and years of experience to learn how to hand-tune!)
- For Montvale processor-based Integrity servers, HP-UX 11i v3 delivers Automated Processor Recover (APR).
|
| The new HP-UX 11i v3 Operating Environments trump the v2 OEs. V3 OEs have more software and the software in highest demand by today’s mission-critical virtualization installations. At installation and update time, one kit and installation procedure brings the entire OE software set up to date. |
Flexibility with partitioning |
|
Integrity Virtual Machines—sub-CPU partitioning available for HP-UX 11i v2 and v3, has these advantages on v3: online guest migration, CPU capping, the hpvmsar tool for performance analysis, and size - up to 8 virtual CPUs.
Dynamic vPars resource movement for CPUs is available for all HP-UX 11i releases— but only v3 enables memory migration.
Dynamic nPartitions, famous for avoiding downtime, also increases flexibility for system administrators who want to reconfigure online.
