P9D-E/4L is the flagship model of ASUS UP Denlow server boards. The board is perfectly designed with powerful I/O expandability and digital power solution increasing VR power efficiency up to 94%. The versatile and highly reliable P9D-E/4L is ideal for data center front-end, firewall, gateway, storage, SMB print/file/mail/exchange server, and more.
Powerful PCI-E expandability, advanced I/O technology
The ASUS P9D-E/4L provides 3 PCI Express 3.0 x8 slots and one ASUS PIKE support. Along with the ASUS technology, this board presents powerful PCI-E expandability. The P9D-E/4L server board is built to support up to 4 USB 3.0 ports. USB 3.0 transfers data 10X faster and is also backward compatible with USB 2.0.
Design to support legacy PCI device applications
Besides the PCI-E technology, P9D-E/4L keeps the legacy PCI slots on board which can fulfill various customers' requirements. Customers can move their existing legacy PCI add-on cards to P9D-E/4L, and still benefit from Intel Xeon E3-1200 v3 processor family and DDR3 memory technology to their solutions.
High power efficiency with premium components and digital power control
ASUS-exclusive Beat Thermal Chokes and Dr. MOS (MOSFETs) improve the voltage regulator (VR) power efficiency. The Beat Thermal Chokes handle the pressure with ease, as a unique fin design results in around 4°C lower choke temperatures for added stability, which is increased exponentially by use of highly conductive and efficient gold-treated coating. This translates into minimal-loss power delivery. Besides, with proven stable circuit integrated, Dr. MOS optimizes switching performance.
Digital CPU power
Digital CPU power controls work perfectly together to match digital power signal (SVID) requests from the CPU, with ultra-fast sensing and response efficiently delivering precision power. Accurate delivery reduces waste, and provides more stable voltage. Thus, P9D-E/4L VR is up to 94% power efficient.
Quad Intel I210AT Gigabit Ethernet
The ASUS P9D-E/4L ships with quad server-class Intel Ethernet ports with the I210AT controllers, which doubles queues compared to previous-generation Intel 82574L controllers. This is better for virtualization applications. In addition, the quad LAN teaming ports provide high networking bandwidth with load balance and fault tolerance functions. This design greatly reduces data processing bottlenecks during network traffic.
SATA DOM (Disk on Module) ready
A SATA DOM is a flash drive simulating a hard disc which can be used without additional software or drivers. It is particularly helpful within embedded computing systems or thin clients. ASUS-exclusive design adds an onboard 4-pin power connector and USB header to make SATA DOM installation simple and easy.
Friendly design for front I/O, front VGAIn The Box
An accessible rear power button is reserved onboard for use as front panel ports when reversing the server board. An extra 15-pin VGA header features front-panel monitor connectivity, helping customers with greater flexibility. These designs provide flexible I/O integration for users to fit in various computing environments.
