Data center technology expansion

Learning the data center technology is very important for the cabling system industry. This article gives a comprehensive introduction to the data center technology and provides an idea for the future network system design and layout, we believe that with the continuous development of data center technology, the network system will be improved in the future.

"The decline in network conditions is a disaster for us," said Care Group Telecom manager, one of the largest hospitals and medical centers on the East Coast, "At that time, we had an evaluation board to rebuild our data center technology and the entire network system to maximize the technical and voice performance of the data center. However, this disaster has put this task ahead of time ." She added.

The network evaluation and design board is organized by the company's internal I. t. together with the Chief Information System Operations Officer, planning execution manager, Product Planning Director, telecommunications Director, network manager, and other I. t. team members, including external consultants and major vendors. Contractors, consultants and vendors are committed to the design and layout work and suggest using 10-Gigabit trunk cables and 6 types of horizontal cabling on servers and equipment cabinets of new data center technologies.

The team organized the design and installation of the new network system through a phased plan. In the first stage, an enhanced 6-class copper cable infrastructure was used to redesign existing data center technologies. The second stage includes replacing the 10g trunk cable with the data center technology and using 6 types of horizontal wiring between the equipment and server cabinets. These two initial phases will enable the enhanced 6-class channel solution of occuhit/logram to meet the speed and bandwidth required by the data center technology. This will provide Care Group with reliable network system assurance and protection against future disasters. The next phase will include upgrades to cables by renovating existing devices and all new devices that comply with the octron/logram category 5 and 6 solutions, this will be determined by the usage and Data Density of each site.

Unsatisfactory growth

With more than 13000 employees and 2000 medical staff, the Care Group provides the community with basic Care and extensive professional services. There are also large hospitals and many small clinics and physician clinics.

The data center technology of two major teaching hospitals at Harvard Medical School was merged five years ago. "In a short time after that, we merged other medical centers and our cabling infrastructure was working well at an estimated growth rate of 30-40% ." "The integration of data center technologies doubles the overall network demand and reaches the limit," said the telecommunications director of the Care Group healthcare system. The 12 feet length of each jumper makes this problem more complicated. If the connection port is only 2 feet far away, you can imagine how messy it is. Redundant Jumpers are loosely distributed on the cable management rack and are circled through the distribution frame, which makes it very time-consuming to describe the trend of cables between two connection ports, not to mention moving, adding, or changing."
From human network to Security Network

"During the four days of network interruption, all documents and lab reports were manually moved to what we call the 'human network'," said the telecom manager at Care Group Hospital. All data has been stored in a backup system so far, but we cannot access files, administration, and finance from the network, in addition, you can only access certain areas through a limited dial-up system when performing important tasks. Fortunately, we have not lost our telephone system, which consists of lines connecting 15000 to major locations, but we soon discovered how critical the data system plays in our daily work. When we integrated data center technology five years ago, we used the best equipment and placed a SONET loop to connect to multiple sites. Now the main sites in the medical center are connected together with data center technologies through a OC-12 SONET loop ."

The rapid growth in a short period of time makes the old data center technology messy. Redundant Jumpers are loosely distributed on the cable management rack and circled across the distribution frame, which makes it very time-consuming to describe the trend of cables between two connection ports.

The first phase of upgrading the core network is to redesign the data center technology, including 100% backups, to provide a completely secure network. In the new data center technology, all the cables in and out of the switch ring are through two major switch switches A and switch B ). When one of them becomes invalid, the other immediately acts as a replacement.

Main Control Center

The repaired data center has an area of 5500 square feet, an environment 24 inch off the ground provides sufficient space for cable trays and power splitters, and provides ample air flow between rack equipment and data center technology storage cabinets. There are also 14 cabinets in the data center, each containing servers dedicated to specific departments of the Care Group. The core column in the center of the data center technology is the main control center of the data center technology, where the standby switch and network hub of the storage area network are placed. Each column is connected to the core device column through 6 types of elasticsearch/rogalang cables.

"The combination of Class 6 horizontal cabling with Class 6 high-density and 48-port distribution racks of the six categories matches the channel's performance can be optimized. Therefore, it can handle the customer's requested gibit bandwidth and high-speed applications ." The manager of the Care Group consultancy explained, "Each 48-port distribution rack has 24 vswitch A ports and vswitch B ports respectively. The operation of all major devices depends on the class 6 distribution frames of occucumber and the patch cords with custom lengths. We specify the position where the jumper is cut according to the installation environment, because we want to avoid excessive redundant cables. These are provided to us by our sellers ." He added.
All Blue Jumpers are connected to switch A, while green jumpers are connected to switch B, which ensures backup and easy identification.

To distinguish the Jumpers connected to vswitch A from vswitch B, these jumpers are color-coded in blue and green and neatly and orderly stored in the otron/logalang distribution frame. In addition, all distribution frames are precisely labeled with vswitches and end-to-end identification numbers. This makes it easier to move, increase, and change.

Expand the backbone network capacity by 10 times

The second phase includes installing a 50 micron multi-mode optical fiber cable from occucumber to enable 10-ge Ethernet to connect to more ports by connecting to occucumber's rack-mounted ORMMAC Optical Fiber manager. The backbone network includes 1200 cable ports, which are the intermediate core layer serving the rest of the device layer. All cables at the core layer of the cable manager are methodically routed from the rack device to the server layer of the Cabinet through the underlying cable tray. The blue and green jumpers line from the top of the cable manager and the distribution frame to enter the core cable distribution layer. In addition to placing an empty shelf in the rack, additional cables are also placed in the cable tray for any expansion and upgrade.

Future Network System

All hospital and external facilities whose cabling base is not up to standard are rewiring. After obtaining standard design and deployment diagrams from the data center technology, we will continue to use all quality-guaranteed cables and connectors using the ochat/loglang channel solution. The telecom director of Care Group said, "whether it is a category 5 or 6 system, we are sure that all cables and connectors have been fully tested and certified, meets the latest TIA/EIA industrial requirements. All installation work will be performed by the installation provider with the full responsibility of the otron/logram certified installer. Our employees, including our internal employees, have also been certified by occuhit/logram ."
Each cabinet is connected to the core switch through 6 types of cables and 6 types of distribution frames. The blue cable is connected to switch A, while the green one is connected to switch B for backup.

"Our plan is to make this system play a role over the next many years. With our network evaluation team well planned and designed, we are confident that the newest installed network system with upgraded space can withstand any disaster. This makes our staff focus on a very important point: taking care of our patients ."
