CASwell has released its new CAD-0255 desktop appliance offering a wide variety of connection possibilities, high-speed networking and processing acceleration. The CAD-0255 support "Intel QuickAssist Technology" (QAT) to increase performance and efficiency of tasks for security, authentification and compression. Intel QAT is specifically applicable for this device as it can be equipped with extremely fast 10-Gigabit-Ethernet for local networking plus WiFi and even LTE modules for wireless and cellular connectivity.

The CAD-0255 is based on Intel Broadwell-D processors like the Xeon D with two to 16 cores plus Hyper-Threading for up to to 32 simultaneous threads. The CPU is paired with up to 16 GByte of DDR4 SO-DIMM main memory with ECC support. For wired networking the device can be equipped with two SFP+ 10-GbE ports, four RJ-45 GbE ports, six more GbE ports by switch functionality and one more optional GbE port by mainboard. For optional wireless connections there is one mPCIe port onboard for a WiFi module and one M.2 socket for a LTE module plus SIM card. A "Trusted Platform Module" (TPM) for encryption, authentification and digital rights management is also available for the CAD-0255 and the whole system can be monitored by the "Intelligent Platform Management Interface" (IPMI 2.0).

One of the most interesting and beneficial features is the Intel DH8925C, though. This so-called "Crypto Chip" is connected to the CPU via PCI Express x8 and exclusively dedicated to "Intel QuickAssist Technology". QAT not only gives the CAD-0255 significantly more performance by accelerating encrypted data traffic in a secure network but also reducing overall data size and lowering storage demands by faster real-time compression while at the same time relieving the CPU of some of the processing workloads.
