Ques. to ask Sun and IBM customers re: SSHA. Can your operating system maintain 24x7 availability in a dynamic environment?

Ques. to ask Sun and IBM customers re: SSHA • Can your operating system maintain 24x7 availability in a dynamic environment? • HP’s integrated high availability components are integrated. (PRM is integrated with Psets, WLM, PRM, vpars, npars are integrated with MC/ServiceGuard) to maintain the highest availability… • Are you concerned with unplanned down time due to application faults. If so, does your OS have the ability to self-manage application resources? Or To recover against in-system failures, can your system adjust dynamic partition size based on load? • HP has vPars, Psets, variable page sizing, dynamic tunable kernels,… • To provide the highest availability, does your operating system enable isolation of a CPU to a portion of a system (rather than to an entire SMP or SMP partition)? • HP vpars can… • Do you have requirements to maintain a high availability infrastructure in a multi-OS environment? • MC/Serviceguard, Openview, etc… • Do you want to pay for high availability when you haven’t used it? • Pay per use… *** HP Confidential ***
2001 D.H.Brown “Unix Function Review”Reliability, Availability, Serviceability Reliability Availability Serviceability Score 8.24 7.53 7.26 6.55 6.24 • Solaris leads in this category due to • OL* capability for CPUs/memory/IO • dynamic reconfiguration capability for system domains on E10000. • hot-patching its kernel • live-upgrade feature • HP-UX is credited for good component failure recovery, leading resource workload balance tools, first-class Fibre Channel support, and strong Disaster Recovery options. • Tru64 UNIX has the strongest Cluster File System (CFS). • AIX lags due to not having partitions. NOTE: DHBrown only scores the OS. Sparc CPUs have had major reliability issues with their Caches and is a major cause of system crashes on SUN boxes. *** HP Confidential ***
