Requirements for NAS service port bonding on the OceanStor V3 storage

3

The network port binding mode of OceanStor V3 storage systems is bond4.
After port bonding, the following restrictions apply:
1. You must configure the 802.3ad dynamic link aggregation control protocol (LACP) mode for corresponding bond ports on the switch.
2. The storage system does not support the following port binding modes:
Bonding of both GE and 10GE ports
Bonding of ports on different interface modules or on different nodes
FCoE ports cannot be bonded.

Recommended file block size for NAS services of the OceanStor V3 storage
Recommended file block sizes vary with application scenarios: 1. In media and large file archive/backup scenarios where large I/Os are involved, the recommended file block size is 64 KB. 2. In small file archive/backup, VM, or database scenarios where small I/Os are involved, the recommended file block size is 4 KB. Recommended file block sizes are based on the size of the majority of files: 1. When sizes of the majority of files are smaller than 100 KB, the recommended file block size is 4 KB. 2. When sizes of the majority of files range from 100 KB to 1 MB, the recommended file block size is 8 KB. 3. When sizes of the majority of files range from 1 MB to 100 MB, the recommended file block size is 16 KB. 4. When sizes of the majority of files range from 100 MB to 1 GB, the recommended file block size is 32 KB. 5. When sizes of the majority of files are larger than 1 GB, the recommended file block size is 64 KB.

Bonding of Fibre Channel host ports on OceanStor V3 storage systems
OceanStor V300R001 storage systems do not support the bonding of Fibre Channel host ports.

Method used to bond ports on OceanStor V3 unified storage systems
On OceanStor V300R001 storage systems, you can bond multiple iSCSI host ports. In doing so, the data transmission rate of these iSCSI host ports can be improved significantly (assuming other components do not reach their performance bottlenecks). For details, see Bonding Ethernet Ports .

Bonding of optical ports on a storage device
Storage devices do not support optical port bonding.

Method used to bond ports on OceanStor T Series unified storage systems
On OceanStor T Series V100R005 storage systems, you can bond multiple iSCSI host ports in 802.3ad mode. In doing so, the data transmission rate of these iSCSI host ports can be improved significantly (assuming other components do not reach their performance bottlenecks). For details about this mode, see Tips for Bonding Storage Ports.
