数据中心的网络格局正在发生巨变。 适应性更好、运行效率更高的组合式基础架构将取代过去灵活性不足且相互孤立的传统数据中心结构,快速获得显著增长,并走向普及。
组合式基础架构采用一种现代化的软件定义方法来进行数据中心实施。 这意味着,通过使用 NMVe 和 NVMe-over-Fabric 协议,您将可以采用一个更通用的架构,而不必构建专门的存储区域网络 (SAN)。
Whereas previously data centers had separate resources for each key task, composable infrastructure enables compute, storage and networking capacity to be pooled together, with each function being accessible via a single unified fabric. This brings far greater operational efficiency levels, with better allocation of available resources and less risk of over provisioning --- critical as edge data centers are introduced to the network, offering solutions for different workload demands.
Composable infrastructure will be highly advantageous to the next wave of data center implementations though the increased degree of abstraction that comes along presents certain challenges --- these are mainly in terms of dealing with acute network congestion --- especially in relation to multiple host scenarios. Serious congestion issues can occur, for example, when there are several hosts attempting to retrieve data from a particular part of the storage resource simultaneously. Such problems will be exacerbated in larger scale deployments, where there are several network layers that need to be considered and the degree of visibility is thus more restricted.
企业急需一款更具创新性的数据中心协调方法。 而这需要精简网络架构,以便顺利迁移至包含较少网络层的组合式基础架构,进而提高透明度,并减少拥堵。
这种新方法将简化数据中心实施,无需过多投资购置昂贵的硬件,而且还可大大降低延迟和功耗。
Further, the integration of advanced analytical mechanisms is certain to be of huge value here as well --- helping with more effective network management and facilitating network diagnostic activities. Storage and compute resources will be better allocated to where there is the greatest need. Stranded capacity will no longer be a heavy financial burden.
利用大幅优化后的架构,数据中心将能够轻松迁移至组合式基础架构。 网络管理者将可以更好地了解流量层面发生的情况,并及时部署适当的响应措施。未来投资将更加有的放矢,提高系统利用率。
