Data center management personnel are expected to change in 2018. Data Center in 2018
The year 2018 is approaching. People in the data center industry predicted the development trend of
requirements, and the data center is de-stacked.
Third, the basic network changes from L2 forwarding to L3 forwarding. In L2 Networks, broadcast storms or loops often occur. Using a layer-3 approach can not only reduce loops, but also improve network bandwidth utilization. Although the three-tier network configuration is complex, it can be deployed automatically through the Controller. As long as the port
not updated yet. Without knowing it, DS will still use this old ing request to respond, but the ToR switch of the receiver finds that the target server is not in its own domain, the system will forward information to DS to notify DS that the ing has expired and trigger DS to update the ing.

Views, stored procedures, triggers, and so on have long been heard, but they have never been really touched. They have been in a future State and cannot be escaped.
What happened to Data
modified when the machine is down, the machine status cannot be used as the query condition for the table. So I thought of using the card number and the computer time as the query condition. The time value obtained by Datatime in vb.net is included together with the date, which makes time conversion troublesome. It takes a long time to query the machine status. The IDC is about to end, and there is no need to change the table. Let's do it first. desi
Data center management diary-, data center 2014I'm curious. Are there so many people surnamed Wang?
Lenovo's after-sales service has come several times, all of which are surnamed Wang. The master who arranged the line is also surnamed Wang... This reminds me of the amazing old Wang next door.
This morning, I encounter

Jingan Classic Network as the country's first IPV6 commercial data center, the current IPv6 use of more than 180,000, its strong IPv6 operational strength and rich IPV6 operating exp

This core is provided by the aggregation layer that integrates various service modules and layer-2 switching functions. Finally, the access layer physically connects the server to the network. Server components are usually 1RU high device stacks in the device racks and interconnected top-of-rack (ToR) or end-of-row (
