Cisco: Nexus Switch
Cisco Systems(CSCO) in its ongoing mission to build the data center of the future is offering a way for other server vendors to plug their blades into unified fabrics powered by Cisco networking gear. Cisco announced the release of their Nexus 4000 Blade Switch.
The Nexus 4000 blade switch supports the NX-OS operating system that is central to Cisco’s “Data Center 3.0″ vision for a converged data enter network that allows server and storage networks to connect seamlessly. The blade switch allows for integration with non-Cisco blade chassis – although no other vendor options have been announced at present.
Bob Nusbaum, product line manager for Cisco’s SAN switches, stated Cisco’s approach will support FICON, NAS/iSCSCI and Fiber Channel over IP, in addition to FCoE and CEE.
Cisco IOS Patch for TCP Flaw Released
Cisco (NASDAQ:CSCO) has just released a critical patch out for its IOS operating system fixing a TCP flaw that could trigger a Denial of Service (DoS) condition.
“By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely,” Cisco’s warns in its advisory. “If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted.”
In other words, a flaw in TCP could have enabled a DoS attack. Have you patched your IOS today ?
- I think this is just another reason to use vyatta or PFSense.
