Advanced Power Management / Wake on LAN
The S2Konnect N-3010AVB 10/100/1000Base-T Adapters, support power man agement as defined
in the PCI Bus Power Management Interface Specification V1.1 and Net work Device Class Power
Management Reference Specification V2.0. The power management features are implemented
according to the Advanced Configuration and Power Interface (ACPI) Specification V2.0.
The S2Konnect N-3010AVB Adapters utilize an auxiliary power supply to keep some parts run-
ning. This setting enables the network device to "Wake on LAN".
The Wake on LAN functionality uses three mechanisms to create a wake-up event:
•
pattern match
Incoming packets are compared to up to seven patterns stored in a pattern matching table. A
match causes a wake-up event.
•
Magic Packet™
The incoming data stream is searched for a so-called magic packet frame that consists of 6
bytes of OxFF followed by 16 iterations of the adapter's MAC address, If this sequence is
found, a wake-up event is created.
•
link change
Any change of the link status from "link down" to "link up" will cause a wake-up event.
Wake on LAN is supported by Windows 98 SE, Windows Me, Windows 2000, Windows XP, Win-
dows Server 2003, and Windows Vista/Windows 7. For information on other operating systems
sup porting Wake on LAN, check the appropriate readme(s) on the Marvell web site.
Reliability
The S2Konnect N-3010AVB 10/100/1000Base-T adapter, PCI Express come with a variety of re-
liability features, They aim at maintaining a connection as long as possible. This is reached by
redundant or grouped links (link aggregation).
The driver functions help to monitor the health of adapters and their ports enabling pro-active
network management. The reliability features are described in the following sections.
Link Aggregation
Link aggregation or Trunking is a method of combining physical network links into a single logical
link for increased bandwidth. With link aggregation, it is possible to increase the capac ity and avai-
lability of the communications channel between devices (both switches and end stations) using
existing Fast Ethernet and Gigabit Ethernet technology. Two or more Gigabit Ethernet connections
are combined into a team in order to increase the bandwidth capability and to create resilient and
redundant links. A set of multiple parallel physical links between two devices is grouped together
to form a single logical link. Link aggregation offers an effi cient and low-cost solution to increase
bandwidth between server and switch. Another advan tage it provides is that if a connection fails
completely, the remaining links can take over the traffic and thus replace the broken line.
Link aggregation also provides load balancing where the processing and communications activity
is distributed across several links so that no single link is overwhelmed.
By taking multiple LAN connections and treating them as a unified, aggregated link, practical bene-
fits can be achieved in many applications.
Link aggregation provides the following important benefits:
•
higher link availability
•
increased link capacity
•
improvements are obtained using existing hardware (no upgrading to higher-capacity link
technology is necessary)
