-2
VPI card with 1 QSFP port, a PCIe2.0 x8 5.0GT/s interface, no on-board memory (mem-free), a
tall PCI bracket, and RoHS R6 compliance. Using the legend,
• field M = M to indicate a Mellanox
Technologies product,
• field H = H to indicate an InfiniBand Adapter
Card,
• field T = Q to indicate QSFP QDR,
• field S = H to indicate ConnectX®-2
• field # = 1 to indicate one port,
• field I = 9 to indicate PCI Express 2.0 x8 running at 5.0GT/s,
• field G = B to indicate Generation B
• field X = X to indicate no on-board memory,
• field B = T to indicate a tall bracket, and
• field R = R to indicate RoHS R6 (with no exemptions) compliance
