The 8-port D-Link DMS-1100 Series is a line of multi-gigabit managed switches supporting 2.5 Gbps, 1000 Mbps and 100 Mbps network speeds, with two 10 GbE SFP+ uplink ports.

Each of the eight 2.5 GbE ports can auto-detect the speed of a connected device and adjust itself to the right link rate. Dubbed by D-Link as “cost-effective”, these new switches are compliant to the IEEE 2.5 BASE-T standard and use Cat 5E Ethernet cable, letting customers upgrade to 2.5 Gbps networking speeds without needing to re-cable their network infrastructure.

A second model in the line, the DMS-1100 -10TP, is an 8-port PoE managed switch with an overall power budget of 240W (30W x 8 ports).

Additional features include Layer 2 functions (STP, RSTP, ERPS, 802.1Q/Port/Asymmetric VLAN, Port mirroring, IGMP/MLD Snooping, LACP), D-Link’s Network Assistant Utility, web-based GUI management, SNMP MIB for remote NMS, D-Link Safeguard Engine (security) and DoS attack prevention. “Green” power saving features include LED shut-off, link status, port shutoff, and hibernation.

Though pricing for the D-Link DMS-1100 Series wasn’t given at this time, D-Link did say the two new switches will be available through VARs, channel partners, and retailers early this month.
Over $500 for the non PoE version.
For that kind of money you can get Buffalo's 10Gbps equivalent, although it admittedly doesn't have the two SFP+ ports.
Still, nice to see more products that offer speeds above 1Gbps.
Sub $200 managed switch with Distributed Switch Architecture (stackable switch fabric with each switch port configurable using iproute2 or similar command set) is available today.

If it isn't enough, you just add another one. DSA lets you extend a network bridge across devices as if it was one device. You can choose a device with an SPF or not depending on your needs.

for $400 you can get a fully managed mikrotik switch with 16 SFP+ ports, 2 PSUs that will take 2.5G/5G ethernet SFP+ modules. even though factoring the price pf modules, you get 2x more ports at 160gb/s forwarding capacity vs dlink's 40gb/s. this also allows you to use used SFP+ cards and use SFP+ direct for less.
