Also see : General QuestionsQ: Have there be any recent price updates to the GigaSwift Ethernet adapter cards?
A:
The Sun GigaSwift Ethernet Adapter sells for $285 & the Sun GigaSwift Ethernet MMF adapter sells for $750. Part numbers to be used while ordering are as follows:
Q: What are the platforms supported by this product?
A:
The SunSwift Gigabit Ethernet Adapters are supported on a broad range of platforms. For detailed list, please see the Detailed View.
Q: What are the key benefits of using Gigabit Ethernet?
A:
Product SpecificationsQ: Is the Sun GigaSwift Ethernet Adapter fully compatible with the IEEE Gigabit Ethernet Standards?
A:
Yes, the UTP/MMF adapters are in full compliance with IEEE 802.3ab for UTP applications.
Q: Does the Sun GigaSwift Ethernet Adapter support 10/100/1000 auto detection?
A:
Yes, the Sun GigaSwift Ethernet UTP/MMF Adapters support 10/100/1000 auto detection.
Q: What Gigabit Ethernet switches does the Sun GigaSwift Ethernet Adapter interoperate with?
A:
Sun GigaSwift Ethernet Adapter is compliant with any other Gigabit Ethernet equipment that complies with IEEE 802.3ab standards.
Q: What interfaces do the Sun GigaSwift Ethernet Adapters support?
A:
Bus interface:
PCI 32/64 bit, 33/66 MHz, single slot universal half length. Network interface: Supports MII, GMII, PMA, and PMD network interface. Q: What is the maximum distance for 1000 Base-T UTP?
A:
Up to 100 meters for Category 5 UTP cable.
Q: What is the maximum distance for 1000 MMF?
A:
The distance depends on 2 factors: the diameter of the fiber and the modal bandwidth.
Q: What are the power requirements for this adapter?
A:
5V or 3.3V DC.
12 Watts (2.4A at 5v) typical or 15 Watts (3.0A at 5V) maximum. Energy Star not supported. Q: When does a user set the local MAC address for the Sun Gigaswift Ethernet UTP adapter card?
A:
The network interface of the Sun GigaSwift Ethernet adapter is assigned a unique Media Access Control (MAC) address that represents the 48 bit address for that interface. The OpenBoot firmware reports this MAC address via the local-mac-address property in the device nodes corresponding to the network interface. A system can use the system-wide MAC address (if there is one) instead of the assigned MAC address.
Q: Does the product support Jumbo frames?
A:
Yes, Jumbo Frame support reduces overhead by enabling sending/ receiving larger packet size (up to 9216 bytes) instead of standard Ethernet packet size (up to 1518 bytes or 1522 bytes when VLAG tagging is enabled). The key benefit to the end user is increase of throughput and reduction in CPU utilization. Supported on Solaris 8 and 9.
Q: Are VLANs supported in this product?
A:
Virtual Local Area Networks (VLAN) support is included with the product. VLANs allow groups of network users to exist in different manageable broadcast domains & to create logical segmentation of workgroups. Each VLAN exists as its own separate network, with its traffic and broadcasts isolated from the others, increasing the bandwidth efficiency within each logical group.
Q: Are any upgrades/replacements being planned for the existing adapters?
A:
Yes, low-cost versions are being planned in the Q3-Q4FY04 timeframe.
These adapters sell for the updated prices $285; $750.
Q: Are there any known incompatibilities with switches?
A:
The user may experience interoperability issues when using the Sun GigaSwift Ethernet adapters with SunSwitch; Alteon ACE 110 switch.
There is a known issue with the autonegotiation feature in the 18-port Cisco Cat5 switch blade when working with the GigaSwift ethernet fiber adapter. The workaround is to turn off autonegotiation at the NIC and the switch port. This converts the connection to 1000Mbps full duplex mode.
Q: What impact does the choice between IPv4 and IPv6 have on Sun's network interfaces?
A:
IPv6/IPv4 streams are treated similar to any other stream. Performance benchmarks are ongoing.
Q: Is there a difference in wirespeed on the Gigabit Ethernet cards w.r.t IPv4 & IPv6 implementations? What is the impact of IPv6 on the requirements for the CPU processor speed to support these wirespeeds?
A:
IPv6/IPv4 streams are treated similar to any other stream. Performance benchmarks are ongoing.
Q: Are there any recommendations on product system requirements?
A:
500 MHz of CPU per adapter is recommended, with a minimum of 167 MHz processor to handle interrupts.
A general rule of 1 MHz of CPU power per 1 Mbps may help the user to assess the processor requirement for the Adapter. This rule is based on ttcp results that send maximum speed data streams from point to point. Other system parameters in assessing processor requirements are MTU packet size, single thread/multi-thread and network bandwidth dedicated to a single point. For applications such as data, video streaming and network backup characterized by maximum MTU and maximum network bandwidth dedication, users may apply the 1 MHz per 1 Mbps rule. Q: What features are supported on x86 platforms?
A:
The drivers for Solaris x86 are designed for version 9 update 6 of the OS. The drivers for Linux have been tested on Suse and Red Hat distributions, RHEL 3.0 32 bit, SUSE 8 64 bit. There are a small number of features presently not supported on the Solaris and Linux x86 platform including: Sun Trunking, Jumbo Frames, Multi Data Transmit, and Net Boot. Future releases of the driver may include support for these features. See the supported platforms for x86 platforms supported.
