Application scenarios of automatic thin provisioning

2

Application scenarios of automatic thin provisioning:
Automatic thin provisioning is applicable to various storage scenarios and in most cases can replace traditional LUNs and improve cost-effectiveness. Thin provisioning is service-sensitive.
Its work efficiency varies with the services. It is particularly applicable in situations where high I/O performance is not demanded.
Dynamic capacity allocation depends on the architecture of a file system. For the file systems such as NTFS, the data is stored on the beginning of a disk, and the capacity utilization rate is high even when the data amount is large. However, for the file systems such as EXT, where the data is stored in a distributed manner, automatic thin provisioning may cause the waste of storage resources.

Principles of automatic thin provisioning
Principles of automatic thin provisioning: Automatic thin provisioning provides users with thin LUNs. The resource pool that provides storage space is called thin pool. The system assigns storage space to an application according to its actual requirement. When the assigned thin LUNs fail to meet the requirements, the system assigns extra storage space to the application from the thin pool.

VM disk configuration modes and their differences
There are three VM disk configuration modes: Common: The system allocates disk space based on disk capacity. During disk creation, any data remaining on the physical device will be reset to 0. This mode results in better disk performance than the others, but disks take longer to create. Thin provisioning: In this mode, the system initially only allocates part of a disk's configured capacity. The rest is allocated as needed based on its storage usage, until all of the configured capacity has been allocated. Thick provisioning lazy zeroed: The system allocates disk space based on disk capacity. Unlike common mode, however, any data remaining on the physical device is only zeroed out on the first data write from the VM. This mode creates disks faster than common mode, and its I/O performance falls between that of the common and thin provisioning modes.

Application scenarios of the OSC automatic pass-through function
OSC overheads can be automatically transmitted to the downstream using the automatic pass-through function even if the SCC board is offline. The automatic pass-through function is configured when the SCC board is online and is applied when the SCC is offline.
