The Huawei 3DC disaster recovery management network is divided into a disaster recovery management network and a production management network, and these two networks must be deployed separately.
The QoS characteristics of object services. For applications with different priorities, different buckets can be configured, and the TPS of the bucket can be controlled through QoS.
As well as the allocation of bandwidth resources; for VIP tenants and ordinary tenants in the same system, different QoS strategies can be configured to ensure high-quality
The quality of service for advanced tenants.
(single choice) The network connection is required before the initial configuration of the big data system. The networking of Huawei OceanStor 9000 does not include:
(Judgment) Through the Huawei OceanStor 9000 Device Manager, we can view the real-time OPS performance indicators of the system.
In the HyperMetro active-active data center solution, you need to configure the active-active domain before configuring the dual-single-selection active-active pair.
The active-active domain is a logical concept, which can include two sets of storage arrays and quorum servers that need to create active-active relationships.
