Chapter 3

Intel Itanium Server Blade
The BladeSymphony 1000 can support up to eight blades for a total of up to 16 Itanium CPU sockets,
or 32 cores, running Microsoft Windows or Linux. Up to four Intel Itanium Server Blades can be
connected via the high-speed backplane to form a high-performance SMP server of up to 16 cores.
Each Intel Itanium Server Blade, illustrated in Figure4, inc ludes 16 DDR2 main memory slots. Using
4 GB DIMMs, this equates to 64 GB per server blade (16 GB per core) or 256 GB in a 16 core SMP
configuration, making it an ideal candidate for large in-memory databases and very large data sets.
Each server blade also includes two gigabit Ethernet ports, which connect to the internal gigabit
Ethernet switch in the chassis, as well as two front-side accessible USB 1.1 ports for local media
connectivity and one RS-232 port for debugging purposes.
