有了这些rackid信息就可以计算出任意两台datanode之间的距离,得到最优的存放策略,优化整个集群的网络带宽均衡以及数据最优分配。 distance(/D1/R1/H1,/D1/R1/H1)=0 相同的datanode distance(/D1/R1/H1,/D1/R1/H2)=2 同一rack下的不同datanode distance(/D1/R1/H1,/D1/R2/H4)=4 同一IDC下的不同dat...
grouping age and presence of horns on two types of social distances: (1) the distance goats choose freely at feeding when they have the option of keeping a large distance between each other; (2) the minimum distance possible without agonistic interactions if the goats are forced to feed in ...
If you plan to route cables down through the bottom of the rack, cut a rectangular hole in the floor tile. Locate the hole below the rear portion of the rack, between...
To leave sufficient clearance for cables, leave a vertical distance of no less than 130 mm between the port side of the switch and the interior side of the cabinet door. Before installing a switch, determine the directions of its port side and power supply side in the cabinet/rack (referred...
Select front mounting brackets, rear mounting brackets, and rear mounting bracket guide rails based on the distance between the front and rear mounting rails in the cabinet. Use M4 screws to attach front and rear mounting brackets to each side of the switch. Front mounting brackets, rear mountin...
