Overview
17 Mellanox Technologies
1.2 Features List
• 324 EDR (100Gb/s) InfiniBand ports in a 16U switch
• 65 Tb/s aggregate data switching capacity with ultra low latency
• IBTA 1.3 and 1.2.1 compliant
• Up to EDR link speeds
• N+N power supply
• Chassis high availability
• sMB high availability
1.3 InfiniBand EDR Overview
The Mellanox CS7510 switch system supports EDR, standard InfiniBand data rate, where each
lane of a 4X port runs a bit rate of 25.78125Gb/s. The EDR physical layer is an IBTA specified
physical layer using different block types, deskew mechanism and framing rules.
Both FDR and EDR support Forward Error Correction (FEC), as described in IEEE Std 802.3ap-
2007 (Amendment to IEEE Std 802.3-2005) chapter 74.
1.4 Power Supply Redundancy
The CS7510 platform comes standard with 6 power supplies. Each power supply is capable to
provide 48V
DC
2500W output power.
1.4.1 AC Source Requirements
CS7510 system supports 220V
AC
operation only. No support for 110V
AC
source. Each AC source
should be capable of providing at least 12A input current.
1.4.2 Power Redundancy
The minimum complement of PSUs which allows the chassis to run at full capacity is 3. The fol-
lowing two redundancy options are available:
• No redundancy (combined mode)
• N+N configuration (grid-redundant mode)
EDR is only guaranteed to work with approved Mellanox cables.
N+N redundancy only works with a supply voltage of 220V.
