In addition, it's possible to configure the server with up to 16GB of ECC-protected main memory. Alternatively, a Mylex dual-channel RAID card can be specified to add extra redundancy and boost performance. Ethernet adapter is also integrated onto the XX4 motherboard and there's plenty of room for extra adapters with the six Hot-Plug PCI slots provided. Two 32-bit PCI slots are also available and the large number of expansion slots made it easy for us to upgrade with the Gigabit Ethernet adapters provided by Netgear for our tests. The XX4 chassis features three hot-swap 375W power supplies, intrusion detection and the usual array of sensors for temperature, voltage level and fan activity.
Management software comes as standard and there's support for remote management via a modem.
A rackmount kit allows the XX4 to be mounted in a standard 19in. Indeed, the big plus with a server like the XX4 is the amount of flexibility that it gives you if you're dealing with a growing network.
