It is November 1. Here are HP, due to a slightly offset fiscal year, we are wishing each other a Happy New Year!
A topic that has popped up several times in the past few weeks is File System Performance. I've seen questions about HP-UX 11i v3 file system performance versus Solaris ZFS. I've seen questions about Logical Volume Manager (LVM) performance. Since many customers run Oracle databases on HP-UX, I've seen questions about the performance of the Concurrent and Direct I/O, especially compared to running Oracle ASM.
HP has a whitepaper [PDF] that discusses the results of performance tests that HP has run with an Oracle single instance database to answer some of these questions. We essentially tested the same setup, a 4 socket BL870c blade system with EVA storage, running the different file system mount options. This represents a realistic, real-world type of implementation, unlike some of the unrealistic set ups for large commercial benchmarks.
Earlier this week, I had the chance to have a conversation with a long time HP-UX customer. Like many customers, they are looking at the new HP Integrity blades to upgrade multiple 3 to 5 year old systems. However, we ended up discussing something that many customers also have: they have several legacy applications that are still on HP 9000 PA-RISC servers running HP-UX 11i v1.
It is a story that I've heard many times with different variations. The customer implemented a software package, and it ended up being discontinued, so there is no newer version for HP Integrity servers. However, it still provides an essential function for the business, running away with old hardware, an OS that is several releases behind the current one, and an unsupported application.
When your business is to provide uninterrupted service to customers, any amount of downtime or service interruption is too much. The telecommunication industry is a good example of a torture test for mission-critical computing - especially given today's proliferation of smart phones and the increasing appetite more of us have to share our thoughts with each other in email, texts, voice, photos, and video as it happens, on the spot, and sometimes even with our geolocation id'd. And this is only the beginning.....what's around the corner and what does it mean in your industry?
