Of course, you will need pretty deep pockets to reach this limit, because 32 GB DIMMs will be very expensive when they are first available (my guess is around $4,000 each, at least initially). 46 Server processors and related hardware Using the on-board memory buffer, the E7 processors can run DDR3-1333 memory at data rates of 800, 978 and 1066 MHz. The E7 processors will support AES instructions, Trusted Execution Technology, and Virtualization VT-x, VT-d and VT-c. Intel claims up to 40% better database performance for the top E7-4870 4-socket model, in comparison to the previous generation Xeon X7560 model.

Also, CPU speed has increased to the point where many systems have substantial spare capacity that can often be used to implement data compression and backup compression, again, to help reduce I/O pressure. " While disk capacity has improved greatly, disk speed has not, and this poses a great problem; most large, busy OLTP systems end up running into I/O bottlenecks. Just as there are many factors to consider when choosing an appropriate processor and associated chipsets, there are equally as many considerations when sizing and configuring the storage subsystem.

Since 2006, Intel has adopted a very structured Tick-Tock strategy for developing and releasing new processor models. Every two years, they introduce a new processor family, incorporating a new microarchitecture; this is the Tock release. One year after the Tock release, they introduce a new processor family that uses the same microarchitecture as the previous year's Tock release, but using a smaller manufacturing process technology and usually incorporating other improvements, such as larger cache sizes or improved memory controllers.
