Both switches also support IPv6 routing and dual-stack IPv4/IPv6 implementations for transitioning customers to the new routing protocol. The switches are also designed to support the IETF's TRILL specification for multipath and multihop Ethernet forwarding in the data center, and the IEEE's VEPA specification for offloading switching from hypervisors to physical switches in the infrastructure, HP says.
HP also enhanced its 12500 data center core switch with new software that improves resiliency and performance. IRF has been added to the switch, which allows four of them to be combined into a single logical switch, regardless of where they are physically located, HP says. The 12500 also supports IPv6 in this new software release.
For the campus, HP rolled out the HP 3800 stackable switch. There are a total of nine models in the 3800 line, including 24-port, 48-port, 24-port PoE+, 48-port PoE+ with either SFP+ or 10GBASE-T uplinks, and 24-port SFP switch with two SFP+ uplinks. The switches are based on HP's ProVision ASIC.
The 3800 line also reduces power consumption through support for the IEEE Energy Efficient Ethernet standard, HP says.
In the branch office, HP unveiled virtualized service modules for its 5400zl and 8200zl switches that integrate hypervisor technology from partners Citrix and VMware. The services modules are designed to accelerate application delivery to branch offices while reducing expenses by virtualizing those applications rather than running them physically on a branch office server. The modules, which run VMware VSphere 5 or Citrix XenServer, also reduce power consumption and space requirements, HP says.
For mobility, HP enhanced its Intelligent Management Center software with Release 5.1, which includes integrated mobile network access control. This helps enforce enterprise access of mobile devices and protect the IT infrastructure from unauthorized mobile access.
IMC 5.1 supports 5,786 devices from more than150 manufacturers, HP says.
Despite the breadth of this launch, some analysts are still noting gaps in the FlexNetwork architecture.
"It's still not clear architecturally how they all fit together," says Zeus Kerravala, principal analyst at ZK Research. "What's missing is the piece that fits in the middle, particularly in a mixed mode environment [of multivendor gear]). But it's certainly a step up from where they were in May. I'm happy to see them get to where they are."
Architectures aside, HP also introduced services to help customers navigate the transition from IPv4 to IPv6, and that its 10500 campus core switch, announced in May, is now shipping. HP also said Bethany Mayer, interim head of HP Networking since the departure of General Manager Marius Haas, is the unit's new senior vice president and general manager, effective immediately.
The 5900 switch starts at $38,000. It will be available in the first quarter of 2012. The 12500 with the IRF and IPv6 software is available this fall at no additional cost to existing 12500 users.
The 3800 switches are available now, starting at $4,969. The services modules for the 5400 and 8200 switches are available now, starting at $5,299 for VMware and $4,499 for Citrix.
IMC 5.1 will be available in the first quarter of 2012, at a price of $6,995.
