Description
Product Overview about the IBM 00E2865
The IBM 00E2865 is a network interface card (NIC) designed for use in IBM servers. This particular NIC uses the PCI-E2 interface and has four Ethernet ports, two of which support 10 Gigabit Ethernet (10GBE) using SFP+ transceivers, and the other two support 1 Gigabit Ethernet (1GBE) using RJ45 connectors. In this article, we will explore the various features and capabilities of the IBM 00E2865 NIC in detail.
PCI-E2 Interface
The IBM 00E2865 NIC uses the PCI-E2 interface, which is an upgraded version of the PCI Express (PCI-E) interface. PCI-E2 provides higher bandwidth and better performance than the original PCI-E interface. Specifically, the PCI-E2 interface used by the IBM 00E2865 supports up to 8 lanes, allowing for a maximum bandwidth of 40 Gbps in each direction.
Four Ethernet Ports
The IBM 00E2865 NIC has four Ethernet ports, making it ideal for use in high-performance servers that require multiple network connections. Each port can operate independently at different speeds and with different protocols.
Two 10GBE SFP+ Ports
The IBM 00E2865 NIC has two ports that support 10GBE using SFP+ transceivers. SFP+ is a small form-factor pluggable (SFP) transceiver that supports 10 Gigabit Ethernet. SFP+ transceivers are hot-swappable, which means they can be replaced without shutting down the server.
SFP+ transceivers support both optical and copper cables. Optical cables are ideal for long-distance connections, while copper cables are better suited for short-distance connections. The IBM 00E2865 NIC supports both types of cables, allowing for greater flexibility in network design.
Two 1GBE RJ45 Ports
The IBM 00E2865 NIC also has two ports that support 1GBE using RJ45 connectors. RJ45 connectors are the most commonly used type of Ethernet connector and are compatible with standard Cat5e and Cat6 Ethernet cables.
1GBE is the most common Ethernet speed and is suitable for most network applications. The 1GBE ports on the IBM 00E2865 NIC can also be used for management and control purposes, allowing for separate network traffic for these tasks.
Advanced Features
The IBM 00E2865 NIC supports a number of advanced features that enhance its performance and reliability. These features include:
- TCP/IP Offload Engine (TOE): The TOE offloads the processing of TCP/IP packets from the server’s CPU, improving network performance and reducing CPU utilization.
- Virtual Machine Device Queues (VMDq): VMDq allows for the efficient distribution of network traffic to virtual machines (VMs), improving overall system performance and reducing latency.
- Direct Cache Access (DCA): DCA improves network performance by allowing the NIC to directly access the server’s CPU cache, reducing memory access latency.
- Interrupt Coalescing: Interrupt coalescing reduces the number of interrupts generated by the NIC, improving overall system performance and reducing CPU utilization.
Compatibility
The IBM 00E2865 NIC is compatible with a wide range of IBM servers, including the IBM System x3650 M4, x3550 M4, x3500 M4, and x3530 M4. The NIC is also compatible with a number of operating systems, including Windows Server, Red Hat Enterprise Linux, and VMware ESXi.
Overall, the IBM 00E2865 NIC is a high-performance network interface card designed for use in IBM servers.
