50 –Switchboard products shopping guides of 200 people’s small and medium-sized enterprises
Small and medium-sized enterprises often face two kinds while disposing one’s own networking products puzzledly: The cost pressure results in often facing the choices of price and characteristic while choosing the products; Meanwhile, not causing clearly enough to one’s own IT business demand does not often have clear purpose to the purchase of the products.
Today, we bring and direct against 50 to everybody –The small and medium-sized enterprises switchboard shopping guide’s guide to 200 people’s scale, hope to offer some reference and help when the networking products are purchased for small and medium-sized enterprises.
As enterprises develop to 50 –200 man hour, the requirements for switchboard products further increase, at this moment, there is simple topological planning of network connection in enterprises, include dividing etc. different partial networks. While purchasing networking products, often no longer pursue and integrate the entire apparatus on an apparatus and insert ports at this moment, and mostly adopt distributed arrangement.
Likewise, enterprises of this scale generally have specialized network administrative staff, the application on the network begins to increase too, so, generally need to choose certain network management function products.
1,H3C S1550 can be managed and inserted the switchboard
The first product that we recommended is that S1550 from H3C can manage 48 switchboard products. H3C S1550 switchboard is that the bilaminar linear speed Ethernet of independent development of H3C Company exchanges the products, it is for demanding to possess high performance, high port density and network environment easy to install but intelligent switchboard of the design. S1550 has offered 48 10/100 Mbps ports, copper cable ports and copper cables / SFP mini GBIC It is used in the flexible gigas of copper cables or optic fibre backbone to connect to make the port up. H3C S1550 can offer the economic network solution for trades such as the small and medium-sized enterprises, education, hotel,etc., and can offer the functions characteristics and simple and easy Web such as VLAN division, speed limit of the port, port assembling and QOS etc. to dispose interfaces.
The concrete characteristic of the products is as follows:
Accord with IEEE 802.3, IEEE 802.3u, IEEE 802.3z/802.3ab standard
Flow control way: Full duplex adopts IEEE 802.3x standard, adopt Backpressure standard half duplexly
48 pieces of 10/100M adaptation RJ45 port, support the port automatic turning-over Auto MDI/MDIX
2 pieces of 10/100M/1000M adaptation RJ45 port, one SFP and one giga of optical interfaces multiplex with Ethernet ports
One Console mouth
Support 512 802.1Q VLAN
Support ports to get together: Support 6 groups to assemble the group, 8 ports at most of each group
Offer the control function of bandwidth of ports, the minimum graininess is 64kbps
Support IEEE 802.1p priority agreement mode, support WRR the roll polling of weighting Deployment, support 4 output queues of every port to offer the safe control function of ports
Support the radio storm to control
Support the port mirror image function
Support the aging time of MAC address to set up
Offer Web to manage
Support the staging of the system software of the switchboard
Built-in general supply, 1U steel shell, 19 inches of standard rack construction, technical grade is designed
Reference price: 2600 yuan
2,China is Quidway S2352P switchboard
Quidway S2352P that the second section of products that we recommended come from China. Family property a gleam of inner manufacturer, China for brand unquestionable in influence, what fortes now we come to have a look this facing small and medium-sized enterprises exchanges products to have.
LS-2352P-EI-AC has 48 10/100Base-TX ports, 2 100/1000Base-X SFP ports, 2 1000Base-X SFP ports, are divided into and exchanged two kinds of models of power supply and D. C. supply.
China is that LS-2352P-EI-AC is VRP

Ethernet exchanger manufacturer tries hard to recommend 40/100G to face the data centre virtually
Three exchangers manufacturer will all release the new enhanced products of data centre this week, include the products upgraded to 40Gbps Ethernet in future.
Its first module 10Gbps exchangers of new developing enterprise Arista online publishing, have come out first in the line speed 10G port density.
The software that Extreme releases strengthens the products to allow the customer to manage the virtual machine better, in order to reduce and exchange the quantity of layer in the network of data centre. Force10 declares it will hand over 40Gbps Ethernet exchanger in the second half of this year.
It shows that all these things are released, busy widening it the users Virtual At the range of application, data centre exchange, become the intersection of exchanger and hottest subdividing the market of market continuously. Generally there are thousands of servers in the data centre, each server deposits about about 20 virtual machines, need to increase more bandwidth, management more detailed in granularity, can keep to the control of a large amount of fictitious operating load.
Arista has improved the bandwidth demand with its AN 7500 exchanger. The key exchanger of this framework type is a kind of supplement for there are 1/10G shelf carrying exchangersing.
8 troughs of height 11U 7500, there is 10Tbps that exchanges the capacity, speed L2/L3 10Gbps Ethernet port of 384 lines. The line speed 10G density which this disposition releases before this over Force10, ExaScale E1200 key exchanger of 140 ports – -Though the latter claims to support 420 more extra ports.
The power consumption of 7500 exchangers and each port is 13 watts, to claim is ” most green more ” than it Rival products getting lower 25% still,framework per second throughput, as 5,760 million data packets single. Such outstanding performance, combine with the exchange capacity of 10Tbps, make this exchanger support 40G and 100Gbps Ethernet interface in the future.
Theoretically, the exchange capacity of 10Tbps can make 7500 can support 250 40G Ethernet ports.
Besides E – serial exchangers of Force10, 7500 will also compete with exchangers such as EX8216 of Nexus 7010, Juniper of Cisco and MLX-32 of the rich department,etc. directly.
The starting fare of Arista 7500 is 140,000 dollars, dispose the systematic cost completely probably each line speed port is less than 1200 dollars.
The rival Extreme plans to promote the performance of its existing exchanger with software, the virtual machine helping management to overflow day by day, reducing the network of data centre exchanges the quantity of storey.
XNV software of Extreme aims at allowing the network administrator and manage lifespan to the virtual machining. This software is an additional software module of ExtremeXOS operating system and EPICenter administrative system.
XNV aims at offering automation and parameter of the Internet, is suitable for QoS, ACL, bandwidth speed to limit, and count and statistics of virtual machine. Intention its to want, let physical network – -But not the fictitious exchanger on the server of the blade – -Can control the virtual machine, establish starting point from it until its life ends. This software can offer its exhaustive history, follow situation and report form when the virtual machine is moved in the data centre.
XNV software module will be made available to the users in the third quater of this year, the starting fare is 3000 dollars for 20 nodes.
