What do you need to know about free software? Before installing the driver software, verify that the Windows operating system has been upgraded to the latest version with the latest service pack applied. On the installation CD, open the folder containing the driver installer program Broadcom ethernet 57xx. On each node, the 2 public adapters are teamed, and the private adapter is not.

How to Optimize Bandwidth on a Broadcom NetXtreme Gigabit

Teaming is supported across the same switch or across 2 switches. Gigabit Ethernet is typically used for the following three purposes in high-performance computing broadcom ethernet 57xx HPCC applications:. In our current HPC offerings, only one of the on-board adapters is used. In case of an adapter failure, the administrator can use the Felix package to easily configure adapter 2. Adapter teaming on the host side is neither tested nor supported in HPCC.


PXE is used extensively for the deployment of the cluster installation and recovery of compute nodes. Teaming is broadcom ethernet 57xx not used on the host side and it is not a part of our standard offering.

Link aggregation is commonly used between switches, especially for large configurations. Jumbo Frames, although not a part of our standard offering, may provide broadcom ethernet 57xx improvement for some applications due to reduced CPU overhead. In our Oracle Solution Stacks, we support adapter teaming in both the private network interconnect between RAC nodes and public network with clients or the Application layer above the Database layer. Load Balancing and Failover. Fault Tolerance. When you perform network backups in a nonteamed environment, overall throughput on a backup system adapter can be easily impacted due to excessive traffic and adapter overloading. Depending on the number of backup systems, data streams, and tape drive speed, backup traffic can easily consume a high percentage of the network link bandwidth, thus impacting production data and tape backup performance.

Network backups usually consist of a dedicated backup system running with tape backup software such as NetBackup, Galaxy or Backup Exec. Attached to the backup system is either a direct SCSI tape backup unit or a tape library connected through a fiber channel storage area network SAN. Systems that are backed up over the network are typically called clients or remote systems broadcom ethernet 57xx usually have a tape backup software agent installed. Because there are 4 client systems, the backup system can simultaneously stream 4 backup jobs one per broadcom ethernet 57xx to a multidrive autoloader.

Because of the single link between the switch and the backup system, however, a 4-stream backup can easily saturate the adapter and link. The performance broadcom ethernet 57xx show that as the number of backup streams increases, the overall throughput increases. Although overall throughput increases as the number of backup streams increases, each backup stream can be impacted by tape software or network stack limitations.

For a tape backup system to reliably use adapter performance and network bandwidth when backing up clients, a network infrastructure must implement teaming such as load balancing and fault tolerance. Data centers will incorporate redundant switches, link aggregation, and trunking as part of their fault tolerant solution. Although teaming device drivers will manipulate the way data flows through teamed interfaces and broadcom ethernet 57xx paths, this is transparent to tape backup applications and does not interrupt any tape backup process when backing up remote systems over the network. There are four paths that the client-system can use to send data to the backup system, but only one of these paths will be designated during data transfer.

One possible path that Client-System Red broadcom ethernet 57xx use to send data to the backup system is:. The selected MAC address is essentially the destination for data transfer from the client system. On Client-System Red, the SLB teaming algorithm will determine which of the 2 adapter interfaces will be used to transmit data.

To demonstrate the SLB mechanisms when additional load is placed on the teamed interface, consider the scenario when the backup system initiates a second backup operation: one to Client-System Red, and one to Client-System Blue. When Client-System Blue needs to transmit data, it uses either one of its adapter interfaces, which is determined by its own SLB algorithm. This is important because with both backup streams running simultaneously, the backup system must load balance data streams broadcom ethernet 57xx different clients.

With both backup streams running, each adapter broadcom ethernet 57xx on the backup system is processing an equal load, thus load-balancing data cross both adapter interfaces. The same algorithm applies if a third and fourth backup operation is initiated from the backup system.


Each client then transmits backup data along a route to the target MAC address on the backup system. Purpose Broadcom ethernet 57xx the LAN driver version Need more help? This test verifies the read and write capabilities of the registers of the physical layer PHY. Internal Memory.

This test verifies that the internal memory of the adapter is functioning properly. The test writes patterned values to the memory and reads back the results. The test fails if an erroneous value is read back.This package provides the Broadcom 57XX Gigabit Integrated Controller and NetXtreme C1 NetXtreme Gigabit Ethernet PCI-E driver and.
