What is a KVM Splitter?
by 42U
A KVM splitter, also called a "reverse KVM switch," creates two or more keyboard, mouse, and monitor access points to one computer, and allows all attached keyboards, mice, and monitors to function as though they were connected directly to the target computer.
KVM splitters can be used successfully in a variety of applications. For example, they work well in offices or manufacturing plants that require multiple monitoring stations to accomplish similar or identical tasks. Instead of using (or purchasing) a second computer, a KVM splitter allows two or more users to share the capabilities of one computer without installing software on the target system.
It is important to note that KVM splitters do not allow users to work on different programs. All users accessing the KVM splitter are required to view the same application at all times, as KVM splitters do not provide multiple instances on the same computer, only multiple points of access to the same peripheral connections.

Modes of Operation:Some KVM splitters offer modes of control to limit user activity. "Delay Mode", which permits active users to lock out idled users for a specific amount of time, is the most widely available function. Some products, such as Raritan's PC Share device, allow users to change the delay mode from 2 to 99 seconds.
NTI's PS2 KVM Splitter has multiple modes of operation. For example, "User 1" mode allows only "User 1" to type or activate the mouse, and all remaining users under this mode have "Video Only" functionality. In order for all users to retain keyboard and mouse control, "User 1" is required to change the mode back to "Delay Mode."

The MultiStation allows multiple users to connect on a first-come, first-served basis to a single computer. Proprietary user cables and computer cables must be purchased along with the MultiStation KVM Splitter.

Unresolved gap kvm system
1, a number of KVM management system can also manage its own brand of KVM IP switches and equipment, and with the information storage and applications, a number of IT-related departments need to adopt a new type of switch. This means that some years later, some companies will face different types of KVM switches and equipment companies can not hope that, as a set of common management system exists in the data center. When the customer needs centralized management system, manufacturers will be the previous system, only the KVM switch and equipment away.
2, data center managers are faced with many problems, such as: the budget and very little artificial circumstances, to update the time and data. Although customers are convinced that the future requires a global centralized management system, but the data center is faced with so many external costs, inevitably deferred consideration, thereby reducing the customer's return on investment.
3, each of the cost of KVM switch in a few hundred dollars to several thousands of dollars, if the work of these products can also put it away for the customers, some economically unacceptable. In response to these complicated situations, many of the previous switch was used, and for the company's CFO is also very confusing, "Now that can not be used, why it also installed"?
4, the previous removal of KVM switches and KVM products to replace a whole will inevitably cause conflict and server installation can not work for some time, it is cause-related data center managers and network administrators to consider the total system in the replacement plan, which affect the company's normal working hours.

Computer Analysis of KVM switch
When multi-computer KVM switch more universal application, the user demands of the diverse and increasingly complex, KVM manufacturers continue to develop more innovative intelligent features, the information management personnel, the effective function of the acquisition of new trends to assess the business demand is very important. Note the following new models currently on the market the most advanced product features and functions to provide the system administrator in the procurement of products in the above order of reference.
Interface Connection: Many indoor KVM systems are through the special cable and PS / 2 interface connected, but the keyboard and mouse is a USB interface port can only connect with a USB keyboard and mouse interface, so manufacturers in particular the introduction of KVM the "PS / 2 to USB" adapter to adapter head. But there are only a mouse and keyboard to provide a single USB interface (for example, a number of Logitech models), then the problem occurs. To this end, the current manufacturers are actively engaged in R & D KVM support the latest new models CAT5 specifications.
Hotkey switch: as long as it is in the order of more than KVM, there hotkey (Hot Key) and OSD (On Screen Display) to switch the server in two ways, in other words, the function of KVM, keyboard, through a combination of special keys to switch and control, the emphasis on efficiency and speed of operation of the system administrator, it is very convenient and reliable design.
Intelligent processor: in the above bands are using high-performance KVM microprocessor emulator to manage each KVM port; KVM connection so that all computer can boot at the same time, and to provide automatic scanning, detection and other functions, making KVM is very easy to use and management. In addition, KVM microprocessor intelligent computer can be recorded for each of the CAPSLOCK key, NUM LOCK key, SCROLL LOCK key's use, and has hot-swappable (hot pluggable) function.
Control software: Some models provide sophisticated control software, in order to monitor system hardware and sensors (such as temperature, voltage, fans, etc.), control system components (such as power, blade server, etc.), records of important system events (such as open chassis, the system re-boot, etc.), administrators can remotely manage and respond to system failures.
More synchronous control: In the face of the continued expansion of business demand for rooms, many new KVM can be a different number of computer equipment and managers to provide flexible solutions to more than the effectiveness of control.
Power Management: Power Management KVM will also become the focus of product development. The use of power management features, the system administrator to shut down the system remotely executable, or for any computer or server reboot in order to improve the speed of system maintenance and efficiency. Management staff can remote control the engine room of the computer or server, and stay at home depends on effective power management devices.
Interface Connection: Many indoor KVM systems are through the special cable and PS / 2 interface connected, but the keyboard and mouse is a USB interface port can only connect with a USB keyboard and mouse interface, so manufacturers in particular the introduction of KVM the "PS / 2 to USB" adapter to adapter head.

Visualization of data center management tools
To AMIE, it is an underlying database, the database through the CMDB to help manage data and data relationships. AMEI the graphical interface and data is a direct counterpart, so that is not a drawing tool for AMIE. AMIE is the reverse, from the data in order to reverse the form of graphical display of the shape.
From higher levels of efficiency, we excel in the use of many administrators and Auto CAD drawings V9 or the problems encountered:
First, who is going to integrate these data? In fact, no one. A phenomenon we have seen, when the data center after the initial deployment, each person is the same data, but when you are using Excel or V9 drawing drawings, the data of each individual to start their own change, when data collection is reality the process is very difficult to complete. AMIE speaking for all data in a unified database, only to tune the database, but of course we have different data transfer time to maintain data consistency and integrity.
Second, Excel, and V9 is static, when a person is to change the data when there is no change other people and we do not know whether the change occurred. The data I have with me now is that other people have already made changes? After I made changes to how to get to know other people? There is no way these issues to be resolved. AMEI basis for such a graphics data generated by the mode of expression, these problems can be solved.

Ｔhe difference between KVM and IT architecture to centrally manage
KVM arising from its process of speaking, first just as a switch. Stage in the rack-mounted servers, each server that are equipped with their own mouse, keyboard and display, we will find for each server to have contact with such a switch, is actually a huge waste of space and the cost . Through the KVM switch, allows multiple servers to share a key, mouse and display equipment.
To the operational phase, we can see another kind of demand, the demand for remote management. Operation of the server process, we need to be able to protect the IT system operation and maintenance personnel or management control of the server, then the system needs to be resolved between management and server connectivity problems. KVM birth of this new technology, in fact, to a certain extent in order to help us resolve in the process of operation and maintenance requirements for a link. Therefore, KVM is only a single technology, it's individual and can not be used as a comprehensive solution to data center solutions, the existence of Operation.
In addition, KVM is often only a part of our data center, that is the problem of server connection.
When we talk about data center when the concept of centralized management, in fact, contain a lot of content there.
From a horizontal perspective, focused on data center management is to control all the assets inside the capacity, managerial capacity and the ability to monitor together, etc., which go far beyond the physical server on which the concept of a single object, so that the KVM in the data center only a tool.
Speaking from the vertical, centralized management contains many objects, as I described above about Avocent solutions, and many have mentioned, is to monitor the level. Is only one part of control, how to monitor the operation of IT infrastructure, and how to understand the infrastructure, including servers, network equipment, data center deployment, how to monitor the entire data center environment is not applicable to or suitable for IT infrastructure operating conditions, etc., are all we focus on data center management by domestic demand content.
So, we hear more and more customers are now referred to a problem is the so-called three-dimensional monitoring of data centers, three-dimensional from the horizontal and vertical data center will monitor the needs of all together. Of course to do a single platform, which fully meet the needs of users, or there is a certain distance. However, we do one thing now is to integrate as much as possible the original management of different platforms and management tools, enabling them to concentrate as much as possible, to make full use of a single control platform for a wide range of ideas to meet the needs of users.
So, KVM centralized management and IT architecture have quite a big difference.
To the operational phase, we can see another kind of demand, the demand for remote management.

So, KVM centralized management and IT architecture have quite a big difference.
Talking about the basic concepts from the KVM, learn more about KVM.
The basic concepts of KVM:
KVM means "keyboard, monitor and mouse." These three add up to a group known as the KVM console.
KVM switch is the main purpose of a unified group of KVM console can connect to many devices. This allows users to access and control from the console many computers or servers. Most of the enterprises need to implement the server behind the scenes to help the smooth operation of enterprises. The most common type of server, including mail server, database / file servers, web servers and application servers (SAP, ADP).
As a result of mission-critical enterprise server role, it is usually referred to as data centers or on the server room security environment.
Server room may be small cupboard or room, or it may be a lot of space, which contains hundreds or even thousands of servers. These are usually referred to as data centers. Data center is designed to protect the inside of the server, and provide very reliable power supply and generators; a high degree of physical security, as well as hot and cold high-end ventilation and air conditioning (HVAC) system.
KVM switch is to ensure that the main purpose of a KVM console can connect to many devices, allowing users to selectively from their control of a KVM console or another device.
The advantages of KVM switch:
KVM switches allow one or more users to access and control many servers, so businesses of all sizes can achieve the following advantages:
* To reduce costs - the use of KVM switch, no longer need to connect to each server keyboard, monitor and mouse, so only one or a small number of keyboard, monitor and mouse, you can control and management of many servers. This does not only reduce hardware costs, but also more valuable air space, in addition to electricity and also reduce the demand for air-conditioning systems.
* To enhance business continuity - KVM switch allows for "independent of the network" to visit the company's servers and other IT equipment. Switch itself does not need to rely on the enterprise backbone or network. Therefore, even if their own corporate network failure, IT personnel will still be able to access, control and management of the company's server. Can even make use of KVM switch from a remote location to do a full system reboot.
Not limited to the hardware platform and operating system - KVM switch can be in different server operating environment. And there is no restriction to a specific manufacturer's hardware or operating system can operate. Switch the operation of the enterprise IT environment can use many different manufacturers of servers, such as HP, IBM and Sun, a variety of operating system executable, for example, Solaris, Unix or Windows.

Control software: Some models provide sophisticated control software, in order to monitor system hardware and sensors (such as temperature, voltage, fans, etc.), control system components (such as power, blade server, etc.), records of important system events (such as open chassis, the system re-boot, etc.), administrators can remotely manage and respond to system failures.
More synchronous control: In the face of the continued expansion of business demand for rooms, many new KVM can be a different number of computer equipment and managers to provide flexible solutions to more than the effectiveness of control.
Power Management: Power Management KVM will also become the focus of product development. The use of power management features, the system administrator to shut down the system remotely executable, or for any computer or server reboot in order to improve the speed of system maintenance and efficiency. Management staff can remote control the engine room of the computer or server, and stay at home depends on effective power management devices.

CAT5-KVM switch is the trend of the times!
CAT5-KVM switch is the trend of the times!
From the data center has become the core of every enterprise resources, not only the increasing importance of data centers, those responsible for the management of data center room are the work of the administrators there have been changes, and now they faced the server, storage and network exchange of equipment, a day to deal with different issues, a response to another data center for the upgrade, change and challenges to ensure the smooth operation. Slowly, the room was seemingly busy working on the administrator's getting heavier and heavier, and those administrators to become the first company to come to work, but the last work, often sacrificing holidays but quite the "excellent staff" .
Although the room managers are hard working, and slowly get used to their work, accept the current model, but the problem is that they used to and accepted by, is it can be changed? Is there a way to work so that they become easy, efficient up?
The answer is yes, a seemingly simple change in the wire, you can bring the data center management of the great progress
This change is the emergence of Cat 5 KVM.
Obvious advantages of Cat 5 cable
In fact, the administrator for the computer room, the use of Cat 5 KVM is the most obvious benefits: great progress in space. We know that the engine room through the KVM administrator to manage the entire data center of the dozens or even hundreds of servers, and each data center because of its age and idea-building reasons, the Federation of noise, temperature, and there are a lot of space layout the problem, so obvious a problem facing every manager in the front of the KVM cable if long enough, then he will have to keep moving away to accommodate the location of the "long enough KVM switch," then?
Clearly, we can not afford to let the administrator will not allow moving to become the management platform, with their feet KVM to solve the problem of wire long enough, therefore, for the management of a large number of servers, especially when these scattered throughout the When - This large-scale enterprises is very common, they need a KVM management can be extended to the foot of his ways, and this solution is to wire Cat.
Purely from the distance, the use of Cat 5 cable can be extended to connect from more than 300 meters, the administrator can be the engine room all the KVM to connect to his feet, for a unified management control at the same time, the flexibility of the overall wire also greatly enhanced, for the traditional three-and-line, its length can not be any change in the share space larger wire, but Cat cable with soft texture, small size and high flexibility. For example, three and a common line, such as 1.8 meters in length, 3 meters or 5 meters, if the server from the KVM is not just, it is necessary to buy extra wire length to meet the application environment, but the Cat 5 wire can be free on demand cut into appropriate length, there would be no extra finishing wire is not easy, but also the space occupied by the engine room and the impact of heat and other issues, but also to facilitate routing between different cabinet.

Three main KVM solutions
Pure simulation system
Advantages: the video operation with good results, true color, high-resolution, operating without any sense of lagging behind; safe, completely non-existent IP network face risks; not occupied by the user of any network resources; IP network will not the impact of the interruption of server operation; pure hardware environment, plug-and-play, simple installation, low maintenance.
Inadequate: the distance the analog signal by the restrictions, if more than distance, it can not operate. (Currently 300 meters can be achieved has been the signal transmission) and other shortcomings.
Pure Digital System
Advantages: all users to operate through the IP network, with remote access capability; capacity is relatively easy.
Shortage: the effect of all users by the network of video quality can not be true color and high-resolution, there are certainly lagging behind a sense of the size of network bandwidth and affect the sense of lagging behind; IP resources occupied by each piece of equipment must be occupied by an IP; need increase the independence of the user authentication system to increase the amount of the maintenance of debugging, if the certification
system failures will not be able to work;
Analog-to-digital hybrid system
It will integrate the advantages of a purely analog and purely digital all the advantages of both.

LCD KVM usher in the new darling of the advent of data centers
With the price of LCD monitors continue to decline, as well as the data center to meet the pressing demand for space-saving, LCD KVM appear before us. Although it appears from the name, LCD KVM will display only replaced the LCD, but the real situation is far from being as simple as the evolution of which is much beyond our wildest dreams.
The first is from space, the new generation of LCD KVM seems more like a book, rather than data center management tools, "You can be flat LCD monitor, as close as a book will become a LCD KVM 1U thick book, and then insert the shelves like the same level on his last rack. "who are using the user ATEN KL9116 opponents of this first LCD KVM has commended Canada.
Can "be inserted into the shelves of" thin 1U addition, the dual-slide designOne of the main reasons is that the so-called dual-slide designis in fact fitted with LCD KVM rack server with the sametype slide. As a result, LCD KVM can, moved to a different location, at the same time, in the dual-slide design, LCD with keyboard, mouse, respectivelyindependent, as saying the advertisement said: "want to see will depend on. "operations do not need to, without taking the keyboard, mouse, LCD can be pulled out only to see the status information they need, even if the rack door closed, you can monitor server status at any time, for example network very convenient. This design, in order to provide a standardization of LCD KVM rack installation, it had also strengthened its mobile performance and ease of operation, saving the user the limited investment in equipment. In addition, LCD low power consumption, low heat dissipation, as well as keyboard, mouse integration, so that not only reduced data center cooling and power costs, it is refreshing but also a number of data centers.
Small space, low heat, easy to install, as well as the integration of mobile design, are gradually replaced by LCD KVM so that the original old-fashioned KVM become the favorite choice of managers. We can assume a cabinet of eight data centers, when a user in each cabinet to place a non-LCD KVM, if administrators want to manage cabinet, he has only two ways: First, to each cabinet, left room for CRT displays, and even a space in each display; second is to use a CRT display to move here. We can imagine, the first case, if the room only needs to install a 2U or 3U rack server, then the enterprise is going to buy a cabinet re-do? And the second case, our administrator is not to spend a CRT display run around. If the data center is the key business centers, then the obvious, each cabinet must be placed in a KVM to display real-time data, not only the issue of inadequate space was more prominent, Cabinets enormous waste, and so , CRT displays astonishing power consumption and heat may be a straight line to the data center notice the increase in electricity tariffs. Some people may think the price will be LCD, but it is the old imperial calendar, and now LCD panels have been cheaper for the individual users can afford to buy a LCD widescreen display.

What are Cat5 KVM Switches?
When standard KVM switches are compared to Cat5 KVM switches, the main difference between the two is how target computers are connected. Cat5 KVM switches use Cat5 cabling instead of older-style bulky 3-in-1 coax KVM cables. However, in order to toss those large bulky cables aside, a simple conversion is needed from the target computers? peripheral ports to a Cat5 or RJ-45 connection. This conversion is made possible by an Interface Module or Cat5 KVM switch dongle.
Once a dongle is connected to the computer, a Cat5 cable is linked from the dongle to one RJ-45 computer port on the back of the Cat5 KVM switch. Single-user Cat 5 KVM switches allow the local user to plug directly into the Cat5 KVM switch with a standard keyboard, mouse, and monitor.
KVM over IP switches also utilize Cat5 dongles to connect the servers/devices to the switch, but can be accessed in-band over the network infrastructure. Depending on the KVM over IP solution, access on the remote end will require client software or an internet browser session.
