Use Elasticsearch, Kafka, and Cassandra to build streaming data centers
Over the past year, I 've met software companies discussing how to process application data (usually in the form of logs and metrics ). During these discussions, I often hear frustration that they have to use a group of fragmented tools to aggregate the
HVAC: technical principle of energy-saving air conditioners in data centers
According to statistics, air conditioning consumes 20% of the total energy consumption in the communication room ~ 45%, and some may even exceed 60%. Therefore, to ensure the normal operation of communication equipment, energy-saving should first begin with the large energy-consuming user of air conditioners.
Currently, most of the
MPO/MTP high-density optical fiber pre-connection system is mainly used in three fields: application of high-density environment in data centers, application of optical fiber to building, application of optical fiber to optical splitter, 40G, 100g sfp, connection applications of SFP + and other optical transceiver devices. This article focuses on why MPO/MTP high-density optical fiber pre-connection system
Cabling slot design in data centers
In the data center, all devices are interconnected through optical fiber cables or cables. Therefore, when you enter the data center, you will see various cables connected to different devices. How to wiring so many cables is a learning. The quality of wiring not only affects the ap
Good grounding of metal pipes can reduce interference and improve the line fire protection level of the equipment room. At the same time, the metal cable trough is used as the routing material to make full use of the cable slot's good scalability and easily add the characteristics of cables. Generally, the cable slots are arranged around the devices.
Currently, the parallel layout of cabinets and into racks is more and more common. Generally, a cable slot is arranged for each cabinet, or a cable
Green cloud computing has many benefits: lower costs, faster upgrades, and simpler O M. From the perspective of social interests, it reduces the environmental burden by reducing carbon emissions.
"The energy use of data centers is an important consideration. Cloud solutions are more efficient than traditional systems ." Eric Woods of Pike Research said.
This is because the carbon footprint of IT has recent
Cannot be overly obsessed with virtualized data centers
At present, the industry's interest in data center and virtual environment automation is growing-automation frees administrators from daily hard work, IT professionals are allowed to focus on more strategic projects that can bring long-term practical benefits to the business. However, virtualization automat
modern cooling system
HVAC systems are typically the second largest power consumption system in the data center, with data center Users Group Estimating 37% of the energy consumed in the datacenter. Air conditioning system can only achieve high efficiency when dealing with a small range, in the face of large-scale data center, most cooling system cooling task c
How to better monitor data centers
Enterprises hope that before the problem arises, the intelligent analysis function can bring the enterprise's system monitoring to a new level.
Now, IT is an important capability for the IT department to make proper planning of production capacity to maintain smooth operation. In addition to achieving IT and business goals, IT can help maintain the IT infrastructure of en
The reliability, delay and consistency of the distributed system are general problems, not limited to the database, and Cassandra provides a good solution to the problem.Cassandra claims to be able to achieve the efficient access to database access across data centers, and it is implemented in a way that gives users the tradeoff between latency, throughput, and consistency. Cassandra provides two levels of
Construction solution for local data centers with 150 nodes
I. Local Data Center
When I came into the company last year, there were only 20 people, and now it has grown to 100. At that time, the office was quite small and could accommodate up to 40 employees. By March, the company plans to move its office. In view of the office environment at that time, in fact,
