Manufacturer's product description
Array Control Processors (ACPs) are configured in pairs for redundancy, up to a maximum of four pairs per system. The exact number of ACP pairs chosen depends on the number and frame location of the disk drive configuration. The quantity may also be influenced by workload performance characteristics.

Advantages: Takes 6 disks in a 2U package Disadvantages: Not a great deal
...which allows you to have Raid1 or raid 5 arrays using the 6 internal hot plug disk slots.

HP have a device called the Integrated Lights-Out Standard, this is a device that is integrated into the server and allows you to power off and restart the server as if you were stood in front of it, you can also watch and interact with the boot sequence, load virtual CD's and Floppy disks into the server from anywhere.

Advantages: THREE functions all for one technology / good value for money for all THREE functions Disadvantages: The COPY function gives average results. Ink cartridges are rapidly used up in premium photos
...TRUST in Hewlett Packard was fully established. As months passed through 2004, 2005, 2006, I settled in the routine of traditionally, upgrading from one HP printer to another of a greater, modernised standard to enjoy the benefits of HP technology with respect to everyday printing. So far, in 2007, the year of MODERN DAY electronics, I currently own a 'HP Deskjet F380' that is not just a simple printer. It is actually an ALL-IN-ONE hardware that is designed to combine the functions of (1) printer, (2) scanner and (3) a copier!
