A. Storage sysadmins are needed to ensure the multipath software in servers runs online before controller upgrades.

B. Fewer front-end modules and host links needed.

C. Host path loss prevention in the event of controller failure, controller hard/software upgrades, and even single FC 1 between host and storage.

D. Direct data dispatch to the distributed controllers through front-end modules in one controller enclosure.

A. A leaf node is a fabric network function access node and provides various network devices to access a VXLAN network

B. Spine nodes are core nodes on the fabric network. They provide high-speed IP forwarding and conned to leaf nodes using high-speed interfaces in any scenario, spine nodes do not need to support VXLAN

C. The overlay technology is a tunnel encapsulation technology, such as VXLAN The basic principle is that packets are encapsulated in tunnel encapsulation mode, transparently transmitted on the underlying network, and then decapsulated to obtain original packets after reaching the destination. This is equivalent to a network overlay (overlay) on the underlying network.

D. The underlay network is a bearer network consisting of various physical devices, such as TOR switches, aggregation switch core switches, load balancing devices and firewalls

A. CIFS

B. FTP

C. NFS

D. HTTP

A. 중간 마모 < 25%

B. 중간 정도의 마모: 50% <&&<85%

C. Severe wear > 85%

D. 중간 마모 < 50%

A. 스마트 DAE

B. 엔진(컨트롤러 인클로저) 수준 고장 허용치

C. 대칭형 능동-능동 컨트롤러

D. AI 엔진
