i Not all customers or software applications will benefit from the use of a dual core processor. Compatible software including compatible operating system software, may be required to obtain the full benefit
of this technology
ii Intel EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation)
without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. See www.intel.com/info/em64t for more information including details on which
processors support Intel EM64T or consult with your system vendor for more information.
iii Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See
www.intel.com/products/processor_number/ for details.
iv Hyper-Threading (HT) Technology requires a computer system with an Intel Pentium processor supporting HT Technology and an HT Technology enabled chipset, BIOS, and operating system. Performance
will vary depending on the specific hardware and software you use. See http://www.intel.com/info/hyperthreading/ for more information including details on which processors support HT Technology
v Hardware RAID is not supported on Linux systems. The Linux kernel, with built-in software RAID, provides excellent functionality and performance. It is a good alternative to hardware-based RAID. Please
visit http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00060684/c00060684.pdf for RAID capabilities with Linux.
