Facing 400G, the challenge is to provide, add, and support high-density, ultra-large bandwidth applications in very large data centers that require a lot of space to accommodate a large number of cables. Low insertion loss, high fiber density, easy installation and stable performance are all necessary considerations for a 400G next-generation data center.400GB Network Transmission, if the Mtp/mpo connector we know as a connection interface, can use 32

However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitte

This element can be used for Tomcat 6.0.11 and later versions. You can configure a shared thread pool for all conneins of a service. This process is useful when multiple ctor INS are running, and each connector must set a maxthread value, however, the maximum number of threads that a tomcat instance can use concurrently is always the same as the total number of maxthreads for all connectors. This is because the processing requires too much hardware re

Some things are recorded and will be used again soon.1. Updating complex nested objects from MongoDB to SOLRRecently using Mongo-connector to open MongoDB with SOLR, for simple JSON, update is no problem. The problem we have this time is that if the value of one field in JSON is an array type, or if there is an object nested within it, then what is the whole thing? For example, we insert such a shipment in MongoDB:{ "_id": "555df36ec6cd08ea807a4324
