The clocks have gone back, but networking is only going forward, as this week's news round-up makes clear...

Exchange failover without spares
It's possible to do failover for Microsoft Exchange without the need for dedicated backup servers, claimed Quest Software as it announced Availability Manager for Exchange v1. The software monitors your mail servers, and if one should fail, automatically re-routes traffic and moves those users to a defined secondary server. This can be any other Exchange server in the organisation - no hot-spares are needed.

The aim, said Quest, is to buy time for admins to fix the server outage. Availability Manager is part of Quest's Performance Suite for Exchange, along with an MMC-based Exchange management console and a tool called Spotlight on Exchange, which monitors the real-time activity of Exchange system components and uses red/green indicators to warn of impending problems.

Service reporting box gains NetFlow
Crannog Software and Network Physics have agreed to combine their NetFlow and NetSensory products to produce NP-2000 for managing app performance.

NP-2000 costs from £21,000, and the companies claimed it is capable of combining segment-specific application flow detail with service response, route information and security information from data centre to data centre across the WAN - assuming that the WAN uses NetFlow-capable switches and routers, naturally.

Remote server room control
Smaller server rooms can now be managed remotely over IP, said Raritan as it introduced eight and 16-port KVM-over-IP devices which it claimed cost 20 percent less per port than enterprise-class versions. The MasterConsole IP18 and IP116 switches are 1U rackmount devices which encode the keyboard, video and mouse signals and broadcast them over IP, allowing servers to be managed over the Internet, right down to BIOS level.

Advantages of the IP approach to KVM include the capability for multiple users to view the same server - and of course it is compatible with any server hardware or operating software, Raritan said. The MasterConsole IP devices are priced at £1000 ($1800) and £1430 ($2500) respectively, and support up to 256-bit SSL encryption plus external authentication servers, such as LDAP, Active Directory and Radius.
