Option-Click AirPort Menu for Network Details

If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.

 
 

Apple Unveils G5 Xserve, new Xserve RAID

Send Article to a Friend

Apple Unveils G5 Xserve, new Xserve RAID -- Apple last week lifted the cover on a significant upgrade to the Xserve, its line of 1U (one-unit high) rack-mount Mac OS X-based servers. The Xserve G5 features single or dual 2 GHz G5 processors, a 1 GHz frontside bus for each processor, an 8 GB RAM ceiling, an 80 GB Serial ATA drive with support for up to 750 GB in three drive bays, and an optional slot-loading CD-ROM or DVD-ROM/CD-RW Combo drive. In addition, the Xserve G5 offers two built-in Gigabit Ethernet interfaces, two FireWire 800 ports, one FireWire 400 port, two USB 2.0 ports, and two full-length PCI-X expansion slots on independent buses. (PCI expansion options include video and SCSI support, additional Ethernet interfaces, an Apple Fibre Channel card, or third-party RAID support). Three configurations are available: a stripped-down Cluster Node version (for distributed applications such as video rendering) with dual 2 GHz processors and a 10-client Mac OS X Server license, as well as more traditional Single Processor and Dual Processor configurations with unlimited client versions of Mac OS X Server. Prices start at $3,000.

Apple also revamped the $6,000 Xserve RAID, a 3U (three-unit high) rack-mount system which offers up to 3.5 TB (terabytes) of storage in 14 hot-swappable drive bays. The Xserve RAID connects to Xserves using a 2 Gb Fibre Channel interface. The new Xserve RAID sports throughputs of up to 210 MB/second, and Apple also unveiled support for using the Xserve RAID with Linux and Windows systems. [GD]
