What ports does the Sun Datacenter InfiniBand Switch 36 support?

It features 36 QSFP standard connectors for QDR InfiniBand at 40GbE speeds, with pinouts including TX/RX pairs, grounds, and I2C signals. Supports ultra-low latency (100ns) and 2.3Tb/s throughput, ideal for dense cabling in HPC setups. Minimum cable bend radius is 5 inches.

What are the physical dimensions and rack compatibility?

The 1RU chassis measures 17.52 in. width, 24 in. depth, 1.75 in. height, and weighs 23 lbs. Designed for standard rack mounting with rear/front rail kits. Acoustic noise is 58.9 dBA idling, compliant for datacenter use.

How is power redundancy handled?

Redundant power supplies provide 550W total (5.6A max at 100VAC), divided equally. Connect to separate sources for failover; green AC LEDs confirm status. Operates on one supply but recommends dual for high availability.

What management options are available?

Managed InfiniBand switch with Subnet Manager support for fabric validation and routing. Defaults to DHCP or static IP 169.254.0.36/16. USB-serial console at 115200 baud, 8-N-1 for direct access.

What environmental specs does it meet?

Operates at 41°F-89.6°F (5-32°C), 5-85% non-condensing humidity (max 80°F wet bulb), up to 9840 ft elevation. Ensures reliability in standard datacenter conditions without additional cooling mods.

Is it suitable for HPC clusters?

Yes, 36-port QDR 40GbE with low latency and high throughput excels in HPC. Subnet Manager auto-establishes links upon QSFP cable connection, perfect for Exascale systems or compute node interconnects.

Product overview

The Sun/Oracle Sun Datacenter InfiniBand Switch 36 (SKU: X2821A-Z, Model: IB-36) is a managed InfiniBand switch designed for datacenter environments. It features 36 QSFP standard connectors supporting QDR InfiniBand at 40GbE speeds, enabling high-performance fabrics with ultra-low latency around 100ns and up to 2.3Tb/s throughput. Housed in a 1RU rack-mount chassis (17.52 in. width, 24 in. depth, 1.75 in. height, 23 lbs), it includes redundant power supplies rated at 550W total input power (5.6A max at 100VAC) for high availability. InfiniBand technology with Subnet Manager support simplifies fabric management and link establishment. Ideal for HPC clusters, it operates in 41°F to 89.6°F ambient, 5-85% humidity. Connect via QSFP cables (min 5 in. bend radius) and manage via USB-serial (115200 baud) or DHCP (default 169.254.0.36). Ensures reliable, scalable networking for demanding workloads.
