   2.88Tb/s of switching in a single 1U device."

SX-1000 Product Details
The SX1035 and SX1036 of 40GbE 1U switches deliver industry-leading
latency performance (230ns at 40GbE and 250ns at 10GbE) with ultra-low
power (6.5W per 40GbE port and 3.6W per 10GbE port) and offer flexible
configurations such as:

*) 36-port 40GbE
*) 64-port 10GbE - using QSFP to four SFP+ breakout cables
*) 56 10GbE and eight 40GbE - using QSFP to four SFP+ breakout cables
*) 48 10GbE and 12 40GbE - using QSFP to four SFP+ breakout cables

Product Briefによると、SX1035は "Lite L2" switchということで、
いくつかの機能が SX1036から外されています。対応するソフトウェアも

"Mellanox Accelerates Hadoop and Memcached for Web 2.0 Applications"
 May 9, 2011

  "The Hadoop performance results, demonstrated with the known Terasort
   benchmark (an I/O intensive benchmark for Hadoop), showed that the
   total job runtime was cut in half when using Hadoop-Direct  and
   Mellanox RDMA-enabled ConnectX-2 InfiniBand or 10GbE with RoCE-enabled
   network adapters compared to traditional Ethernet alternatives.
   Hadoop-Direct is transparent to Hadoop users and applications, and
   does not require any modification for existing application and usage
