X79 Chipset Finalized as Ten SATA Interfaces

X79 Chipset Finalized as Ten SATA Interfaces After some torment, the X79 chipset used with the LGA2011 Sandy Bridge-E processor still failed to reach its original level of expectation. There will only be ten SATA disk interfaces.

The X79 chipset targets the desktop, only this version, and the corresponding server platform has four different specifications of the chipset Patsburg-T/D/B/A. The X79 was supposed to be equivalent to the second-stage Patsburg-D, but because of problems it was downgraded to Patsburg-B/A, which lost four SATA/SAS 6Gbps and PCI-E 3.0 channels between the processors.

As a result, the number of SATA disk interfaces of the X79 chipset is limited to ten and is divided into two groups: two SATA 6Gbps and four SATA 3Gbps from the standard AHCI controller, the same as the current 6 series chipset; Four SATA 6Gbps are added through the Storage Controller Unit (SCU).

Special attention should be paid to that, because of different sources, AHCI and the SATA interface managed by the SCU cannot be used to build a RAID disk array. A combination of strips can only be used in the operating system.

As for the new platform's support for PCI-E 3.0 expansion slots (not the PCI-E 3.0 storage channel), Intel is working hard to verify it, but when it can be completed and released, it can't be guaranteed.

The Sandy Bridge-E processor and X79 chipset are scheduled to be released in November, and it is reported that Intel will introduce a new stepping X79 at the end of the year to make up for the functional features.

Linear Encoder

Draw-wire sensors of the wire sensor series measure with high linearity across the entire measuring range and are used for distance and position measurements of 100mm up to 20,000mm. Draw-wire sensors from LANDER are ideal for integration and subsequent assembly in serial OEM applications, e.g., in medical devices, lifts, conveyors and automotive engineering.
