Jasper Forest is first Nehalem with integrated memory controller
One of the most interesting things Intel talked about was its recently launched Jasper Forest embedded Xeon processors for storage servers. Jasper Forest is based on Intel's Nehalem architecture, yet it's using the Ibex Peak chipset also known as the 3420 in this market space. This is the same chipset that the Lynnfield and Clarkdale processors are using and on the desktop side it's known as the P55/H55/H57/Q57.
In other words, Jasper Forest is something of a hybrid solution from Intel, as the CPU features a built in memory controller just as the Lynnfield and Clarkdale processors, but it retains the ability to use triple-channel memory. It also has an integrated PCI Express 2.0 controller that delivers 16 lanes of bandwidth that can be employed in various ways depending on the system and server configuration. One feature Intel is touting is the PCI Express Non-Transparent Bridge Failover option that takes up eight PCI Express lanes and adds a second, redundant platform inside the same server. This secondary setup will take over if the primary would fail, although this is a rather costly solution.
