2014, the global IDC market growth rate slightly increased, the overall market size reached 32.79 billion U.S. dollars, growth of 15.3%. The main driving force of its growth is from the Asia-Pacific region, where IT companies, internet companies and telecommunications companies invest in data centers to boost the overall market. 2014 China IDC market rapid growth, the market scale reached 37.22 billion yuan, the growth rate of 41.8%, the Internet market rigid demand to pull IDC rapid growth. In the past six years, China IDC market compound growth rate reached 38.6%. The rapid growth of IDC market has put forward higher requirements for management and maintenance, this paper introduces the application of the Intelligent Infrastructure Management system of Rosenberg Pyxis based on an IDC managed data center cabling system.

One, IDC Data Center integrated cabling system overall planning characteristics

IDC (Internet Data Center) is an internet datacenter, and the main applications of IDC hosting are Web publishing, virtual hosting and e-commerce. It is developed rapidly with the development of the Internet, IDC is not only the center of data storage, but also the center of data flow, it should appear in the Internet network in the most centralized data exchange. IDC is accompanied by people on the host hosting and virtual hosting services put forward higher requirements of the situation, is the Internet Enterprise Division of labor more refined products.

IDC market is growing rapidly, facing more challenges and requirements, the public cloud with rapid deployment, scalability and low prices for small and medium-sized customers more and more attractive, its growth rate of twice times the traditional IDC hosting business, the traditional IDC hosting market is facing unprecedented challenges Customer requirements for security and availability have increased with the development of cloud computing, to reduce the risk of traditional data center outages, the construction of a distributed data center, centralized management through a unified platform is also the trend of IDC data center development.

As the physical channel of data transmission, the importance of the integrated cabling system is self-evident. In the planning and design, we must fully consider the application needs and trends of IDC, to ensure the stability and reliability of existing systems, while taking into account the future expansion and upgrade. Traditional IDC data Center cabling system generally consider the following points:

High reliability: The stability and security of the data center is the most important, the disruption of any business will cause significant economic loss and serious social impact. System architecture should be in the data Center standard tia-942-a planning requirements, the use of higher-level cabling solutions, including product performance, installation of the process, fire-retardant capacity and so on.

High scalability: With the emergence of many new technologies and applications in the Internet, the installed capacity of the server is growing rapidly, and the bandwidth requirement is higher. Cabling System design must consider the partial redundancy, while the cabling product has a certain expansion function.

High utilization ratio: the increase of cabinet density, the number of stand-alone cabinet support server greatly increased, cabling system in the use of high-density scheme, how to fully utilize the idle redundant link, through the timely switch port, the maximum possible to enhance the load capacity of data transmission channel, has been an important embodiment of IT operations and maintenance management capabilities.

Real-time High: IDC hosting a wide range of customers at different levels, the daily operation of the main work for job orders and alarm processing, wiring system physical link and its corresponding port must be quickly find and locate, in order to timely and effective guarantee the timely communication and data transmission of the link.

Traditional cabling system can not effectively meet the high-level IDC data Center new operation and maintenance requirements, therefore, the high efficiency of intelligent cabling management system will be more and more introduced IDC integrated cabling System solutions. Intelligent Cabling Management system is composed of software and hardware, without changing the wiring structure, through the active module to monitor the real-time connection status of jumpers, thus improving the efficiency of operation and maintenance management, reducing the cost and time of the human maintaining, timely and effective to ensure the rapid realization of business applications.

Second, an IDC data center Intelligent Cabling Management overall plan

IDC managed data Center uses ansi&tia-942 Tier4 standard design and construction, set DC,TELEHUOSE,DR,NOC,SOC and other services in one of the new generation of composite data center; unique detached, 6-storey building, seismic 7, the total area of 13000 square meters, 5 and 6 floors of the office area, 1 (including power zone) to 4 floor for the production area, about 1500 cabinets, power SLA commitment of up to 99.995%, professional (non-outsourced) operators more than hundred people, support the same city of the disaster preparedness, with a sound security management system. With more than 15 years of operational experience, has been repeatedly the best data Center maintenance service provider of the year.

The project was designed to use a non-intelligent general cabling system, as the project infrastructure gradually completed and the customer's intention to negotiate a higher service requirements, operators realize the traditional manual management maintenance mode inefficient, in order to improve service level and brand effect, improve management efficiency, save operating costs, The operator decides to change the design of the data center cabling system, uses the intelligent cabling system, uses the electronic wiring frame, replaces the traditional ordinary non-intelligent wiring frame, and with the intelligent cabling System software, realizes the monitoring of the basic physical cabling, thus making up the last short board-physical layer monitoring of the network OSI seven-layer model monitoring and management. With the help of electronic software platform and wiring rack port LED lights, maintenance personnel can quickly according to the information, reduce the range of physical failure, reducing troubleshooting time, improve the overall maintenance efficiency, helping maintenance personnel from the traditional cumbersome time-consuming manual operation.

The project in the basement 1 and 1 to set up two operators to access the data center, two Access data center using 96-cell Gigabit OM3 Optical Cable interconnect, 1 to 4 layer a total of 7 weak data center, two Access data center to each weak data center respectively configured 48-core million OM3 cable, Each floor of the weak data center to its corresponding header cabinet configuration 1600-core fiber optic cable and 800 copper cable, the head of the use of cross-interconnect, and then through the horizontal wiring to the client cabinet, the average per client cabinet configuration 8-core fiber optic cable and 4 copper cable. Regardless of the late expansion, the current access to the data center to the weak data center for 768-core optical cable (including interconnection), the weak data center to the head of the main cabinet for 11200-core optical cable, 5600 copper cable, head cabinet to the client cabinet is also 11200-core cable, 5600 copper cable. From the Access data center to the header cabinet is mainly responsible for the maintenance of the operator, the client cabinet is mainly by the customer's own maintenance, or co-operation with the operator to maintain.

IDC's managed data center focuses on physical link maintenance by adding physical link and link troubleshooting. The connection jumper completes the work order task by allocating the original idle link, and the alarm is removed by switching the link and inserting the jumper. The entire link channel is maintained by the operator and the customer, so it is easy to make communication difficult during maintenance, even the separation of responsibilities, which greatly increases the troubleshooting time. Therefore, in order to improve the overall maintenance service quality, reduce the risk of failure and labor costs, fully consider the return on investment in the case of the following 3 aspects of the selection evaluation, the project decided to use the Rosenberg intelligent Cabling System.

Three, suitable for IDC data Center Intelligent Cabling Architecture

1, wiring structure of electronic wiring frame

There are two main wiring architectures for electronic wiring racks: Single frame architecture and dual frame architecture. Single-use electronic wiring rack instead of the original common wiring frame, mainly for the port-type electronic wiring frame, the number of wiring racks unchanged, and then connected to the switch via jumpers. The main object of the daily maintenance operation is the jumper port to the power port of the switch. When connecting, the jumper must first jump the switch port, and then the power adapter port, however, the power distribution system can only be connected via the trigger of the electrical connection, the other end of the switch port to confirm connectivity must be software immediately through the SNMP protocol from the switch's MIB to the switch port status from down to up, The port gets to the end device Mac. The switch requires SNMP function and open, allowing the power distribution software to read the MIB information, so there are some risks in management. If there are multiple links connected at the same time, it is easy to cause false positives. When removing or changing jumpers, it is also necessary to unplug the power distribution and remove the switch side. Once the link is interrupted, the non-cable itself is connected to quality issues such as removing the switch-side jump line first, the switch port is damaged, the terminal server is down, or the server-side jumper is removed, and the software is unable to identify and help the maintenance staff narrow down the fault range.

Dual frame structure on the basis of a single electronic wiring frame, the addition of an electronic wiring rack mapping switch, the electronic wiring rack and switch between the non-intelligent jumper connection, dual rack structure to the daily operation of the maintenance of the object from the switch port to the rack port changed to a rack port to the rack port, immediately detect the connection between the jumpers.

In this way, the normal jumper plug operation can be monitored to avoid the single frame structure can only monitor one end of the situation, improve the overall management reliability and efficiency, and truly realize the electronic management of maintenance operations.

2, the detection technology of electronic wiring frame

Electronic wiring frame detection technology has many kinds, different manufacturers of technology and connection architecture are different, mainly divided into port type and link type two categories. Port type is also divided into the end taste type (such as electronic micro Switch, infrared sensor) and port identification type (such as rfid,cpid); the link type is mainly divided into nine-pin link type and 10-pin link type.

The end taste type mainly relies on the wiring frame port to the jumper connector's physical sense to judge the jumper plug situation, through the trigger way carries on the detection. Advantages are simple structure, relatively low cost, can use ordinary 8-core jumper. The disadvantage is that other types of jumpers and even other objects (such as fingers, crystal first) are wrongly reported to the software platform for the actual required jumpers; Because only the detection port, that is, only detect the jumpers of the ends of the connector, the jumper itself can not detect the cable, plug and unplug operation must be at both ends of the one by one corresponding Plug and unplug, Otherwise, the same side of the two jumpers will be inserted at the same end, and the two ends of the same jumper can be misjudged. The jumper relationship must be properly carried out when the database is initially created, or it will be difficult to find out when the error is made later.

The port recognition type mainly passes the reader of the wiring frame port, when the jumper is installed, reads the chip information which is pre-placed on the jumper ends to establish the jumper relationship. The advantage is that the information is stored in a large amount, and you can customize the ports and links as well as the basic information about jumpers. The disadvantage is that the cost is relatively high, you need to add a chip on the jumper end of the same can only detect jumpers on both ends of the connector, can not detect the jumper itself cable, plug and unplug operation must be at both ends one by one corresponding to plug and unplug, or at the same time inserting two jumper at the same end, will be mistaken for the same jumper ends

The link type mainly uses the 9-pin or 10-pin module and the jumper, through the additional pin needle to form the detection loop, passes the detection signal through the circuit to the scanning module, then reports to the software platform. Link Type the biggest advantage is real-time online monitoring, through the database comparison detection method, regardless of the circumstances of the Plug and Unplug connection, can automatically identify and carry out the corresponding alarm. At the same time can be batch jumper operation, all the operation through LED lights, do not worry about jumping the wrong port. Bulk jump, that is, you can first down the task, and then physical jump, you can also first batch physical jump, and then through the software alarm platform to confirm, eliminate the alarm confirmation connection. In addition, the intelligent jumper itself also has a certain detection function, once the jumper is broken by external forces, while affecting the detection circuit, immediately generate alarms.

In addition, the 9-pin link type and the 10-pin link type are not only different in structure, but also the scanning mode of the electric matching. The 9-pin jumper features a non-standard RJ45 crystal Head, an additional detection probe, a 10-pin jumper with a standard RJ45 crystal Head, an additional 2 probes for detection at 0Pin and 9Pin on both sides of the standard 8-pin, and a 2-pin increase in the corresponding RJ45 module. 9-Pin link-type system using a single-chip serial scanning method, for the wiring frame using a one-way scan, scanning period is longer, generally at least a few minutes; 10-pin link-type system uses the parallel scanning mode of chip, support 24-way simultaneous scanning, scanning cycle is short, a few seconds to complete.

3. How to deploy the electronic wiring frame

The deployment mode of electronic distribution rack is divided into two categories: serial and parallel.

Serial mode is often said Daisy chain bus structure, the active monitoring equipment is generally used in single-chip processing, through the serial line will be a number of different electronic wiring frame one by one string up. This kind of connection structure is relatively simple, reduce the number of active control equipment, but the reliability of a certain risk, once any node failure will affect the subsequent electronic wiring frame connection communication. At the same time, the electronic wiring frame power supply demand increases, the general four-in-one electronic wiring rack will need to add an additional power module. When the signal is polled, a single electronic wiring frame can only be scanned by daisy-chaining, and the entire scan cycle may take several minutes to complete.

The parallel mode uses the tree topology structure, the active monitoring device uses the chip processing way, provides 12 or 24 management ports to manage 12 or 24 electronic wiring frame respectively, all electronic wiring frame's signal processing uses the concurrent connection way, this way reliability is high, once has the failure, the influence scope is small. Typically a polling cycle may take only a few seconds to complete, while the active monitoring device provides Poe power to the electronic wiring rack, reducing the power supply module's use. Active monitoring equipment through IP access Management network, easy to manage and maintain, reduce the switch port and IP resources waste. Without the use of active monitoring equipment, all electronic wiring racks need to allocate an IP address, through the switch port to be recognized, the overall network management brings an additional burden.

Four, one IDC data Center Rosenberg Intelligent Cabling Management Product Solution

Rosenberg's second generation of intelligent cabling management system PYXIS-II, including monitoring host, management Unit, optical/copper electronic wiring rack, optical/copper smart jumper and OMC cabling management software. Pyxis-ii still uses the 10-pin link technology of the dual frame structure, compared to the pyxis-i, the hardware additional monitoring host, while the software is also optimized for upgrading.

650) this.width=650; "title=" Picture 8.jpg "src=" Wkiol1wwvmljajncaafwkj13jwo324.jpg "width=" 594 "height=" 401 "alt=" Wkiol1wwvmljajncaafwkj13jwo324.jpg "/>

For this case, the PYXIS­-II Intelligent cabling Management System Deployment architecture is as follows:

The monitoring host is typically deployed in an MDA or HDA wiring cabinet, and the nearest monitoring snap-in. Through the front LAN port, configure the IP after access to the user Management network, the monitoring data is escalated to the OMC cabling software, while the software work Order task issued to the management unit. A monitoring host can monitor 24 management units, if the number of network ports exceeds the number of management ports of a single monitoring host, you can increase the host as needed, OMC cabling management software can be integrated management of multiple hosts, hardware and software design can enable users to achieve unlimited scale on demand expansion needs. In this case, the actual use of 2 monitoring hosts for the management of 40 management units. Part of the link later in accordance with customer demand for additional, so the corresponding monitoring host, management unit, electronic wiring rack will be added in the later stages.

The management unit is primarily deployed in HDA wiring cabinets and monitors the distribution cabinets or electronic wiring racks in adjacent HDA wiring cabinets. The snap-in comes with an LCD display and buttons for link viewing and related operations in the field. One Management unit can monitor 24 electronic wiring racks. In this case, the current management of 40 management units, distributed in 20 HDA distribution cabinets, for monitoring 600+ optical/copper electronic wiring rack.

The optical/copper electronic wiring frame is deployed in an MDA or HDA wiring cabinet, with a dual frame structure instead of the original common single wiring frame. The copper electronic wiring frame consists of 24 10-pin RJ45 modules and active scanning modules, the RJ45 module can be disassembled separately, the active scan module is Poe powered via the snap-in and comes with 24 LEDs. The opto-Electronic wiring frame contains 3 24-core LC Interface module groups, which can realize the 1hu72 core, while satisfying both the fusion and pre-connected schemes, and the self-contained cable-up cable, which is also powered by Poe. Monitoring host, the management unit and the electronic wiring frame are connected through the ordinary RJ45 jumper connection communication, without the other interface cable.

The optical/Copper smart jumper has 2 more pins than the normal jumper to monitor the connectivity of jumpers and ports. Smart jumpers can be customized for length and color, and are factory tested for performance with a unique SN number. The number of smart jumpers can be configured based on the number of links actually used.

OMC Cabling management software only need to configure a set to meet multi-user login, and can be granted different permissions. Multi-Department multi-user simultaneous landing maintenance, can be viewed separately, work order tasks and other operations. OMC Cabling management software using a graphical cabinet interface, all the equipment contains common wiring racks, active devices, etc. can be graphically displayed in the software interface. With a database backup tool, you can send alarms and logs to the network manager or to a unified alarm platform by mail or message. OMC Cabling management software does not regularly optimize the upgrade, for IDC Data Center maintenance features, added jumper number Add and query function, for some special functions to provide customized development services.

With high-quality solutions from IDC's managed data center over the years, the Rosenberg Smart Cabling System was awarded the "2013-2015 Data center excellent products and Solutions" award from the China Data Center Industry Alliance. For IDC data centers, the management and maintenance of IT infrastructure will be more complex than traditional EDC because of the multiple leasing and hosting methods, and the stability and accident processing efficiency of the hosted IDC Data Center is an important factor to measure customer satisfaction, so the intelligent cabling system is introduced. Help to greatly improve the management and maintenance efficiency of IDC, improve the overall operation of data center
