balance-rr

This mode uses a round-robin policy; it transmits

 

 

packets in sequential order, from the first available

 

 

slave through the last. This mode provides load bal-

 

 

ancing and fault tolerance.

 

 

 

1active-backupIn this mode, one slave interface is active at all times. If one interface fails, another interface takes over the MAC address and becomes the active interface. This mode provides only fault tolerance. This mode does not require special switch support.

2balance-xorIn this mode, transmissions are balanced across the slave interfaces based on ((source MAC) XOR (dest MAC)) modulo slave count. The same slave is selected for each destination MAC. This mode pro- vides load balancing and fault tolerance.

3broadcast This mode transmits everything on all slave inter- faces. This mode provides fault tolerance.

4802.3a This mode provides standard IEEE 802.3ad dynamic link aggregation. It requires 802.3ad sup- port in the switch, and driver support for retrieving the speed and duplex of each slave.

5balance-tlbThis mode provides adaptive transmit load balanc- ing. Incoming traffic is received only on the active slave. Outgoing traffic is distributed according to the current load on each slave. This mode does not require special switch support.

6balance-albThis mode provides adaptive load balancing through ARP negotiation; both transmit load balanc- ing (TLB) and receive load balancing are supported for IPv4. This mode does not require special switch support, but does require the ability to change the MAC address of a device while it is open.

3000, 3100 specifications

The Q-Logic 3100 and 3000 series are advanced networking solutions designed for high-performance data centers and enterprise environments. Known for their innovative technology, these switches and adapters are tailored for seamless integration in modern computing infrastructures, offering scalability and robustness essential for today's demanding applications.

One of the standout features of the Q-Logic 3100 and 3000 series is their support for high-speed data transmission, reaching up to 16 Gbps in Fibre Channel connections. This capability ensures minimal latency and exceptional throughput, which is critical for applications that require rapid data access and processing, like virtualization and cloud computing.

Both series incorporate cutting-edge virtualization technologies, enabling multiple environments to be managed efficiently through a single physical instance. This support for virtualization reduces hardware costs and maximizes resource utilization, a vital aspect for organizations looking to optimize their IT investments. Additionally, the series provides enhanced Quality of Service (QoS) features, which prioritize data traffic and ensure stable performance across various applications.

Security is another primary concern addressed by the Q-Logic 3100 and 3000 series. They offer advanced security features, including hardware-based encryption, which protects data in transit and at rest. Access control mechanisms are in place to prevent unauthorized access, making these solutions suitable for organizations that handle sensitive information.

The Q-Logic 3100 and 3000 series are built with reliability in mind. They include built-in redundancy features, such as dual power supplies and hot-swappable components, which reduce the risk of system failure and improve overall uptime. This reliability is crucial for businesses that operate around the clock, as downtime can lead to significant financial losses.

Configuration and management of the Q-Logic series are simplified through user-friendly interfaces and comprehensive management tools. These tools allow administrators to monitor performance, configure settings, and troubleshoot issues efficiently, thereby enhancing operational productivity.

In summary, the Q-Logic 3100 and 3000 series stand out as exemplary solutions for high-performance networking needs. With their impressive speed, support for virtualization, strong security features, and robust reliability, these products continue to solidify their position as leaders in the networking technology landscape. As businesses evolve and grow, these innovative solutions are poised to adapt and meet the challenges of the future.
