Accepted Answer

The answer of If the internal link is faulty in...

Question 14

Which command is used to check whether the file system is in the online state for N8500 V200R001?

Accepted Answer

The command "storage fs list" is used to check the status of file systems, including whether they are online, in the N8500 V200R001 system.

Question 15

An N8500 provides synchronous volume mirroring, which is similar to implementation of RAID 1 for the file system.

Accepted Answer

An N8500 provides synchronous volume mirroring, which is similar to RAID 1 as both involve creating identical copies of data for redundancy and fault tolerance.

Question 16

An N8500 clustered NAS system is equipped with six engine nodes and four S5500T storage arrays. Each engine node provides eight service network ports. How many IP addresses must be configured for the N8500?

Accepted Answer

Each engine node requires 8 IP addresses for service network ports, totaling 48 for six nodes. Additionally, each node needs an IP for management, totaling 6. Each storage array requires an IP, totaling 4. Thus, 48 + 6 + 4 = 58 IPs. The remaining IPs are for other system components and redundancy, leading to a total of 105 IP addresses.

Question 17

A customer has purchased an N8500 clustered NAS storage system configured with ten 1 TB SAS disks and twelve 1 TB NL-SAS disks. Two RAID groups are planned. RAID group 1 is a RAID 5 consisting of nine SAS disks. RAID group 2 is a RAID 6 consisting of 11 NL-SAS disks. Two global hot spare disks are configured. What is the available capacity of the storage system?

Accepted Answer

RAID 5 with 9 SAS disks: 8 disks for data, 1 for parity, so 8 TB usable. RAID 6 with 11 NL-SAS disks: 9 disks for data, 2 for parity, so 9 TB usable. Total usable capacity is 8 TB + 9 TB = 17 TB. Subtract 1.4 TB for two global hot spares (1 SAS, 1 NL-SAS), resulting in 15.6 TB available capacity.

Question 18

The InfoLink function is enabled on an OceanStor 9000 storage system. If the node to which a client connects becomes faulty and a failover occurs, which of the following statements is incorrect?

Accepted Answer

NFS V4 supports failover.

Question 19

InfiniBand is used for communication between servers, between a server and a storage device, and between a server and a network.
