Storage Needs for Enterprises and Applications
- Every organization deals with servers. Each server has a disk(s) attached.
- Multiple users/systems in an organization might need to access the common data for that they use file shares (NFS, NAS, SAN)
-
Backup and Archival:
- Backup is generally used to recover the data quickly to resolve temporary issues/device damages etc…
- Backup should be restored ASAP (as quickly as possible)
- Archival is used to recover the data in the cases of disasters or major incidents.
- Achival recovery takes time.
- FileSystem: OS required filesystems (NTFS, XFS, ext) to interact with storage devices
- Blob Storage:
- This is generally hosted by cloud services providers or storage providers. To interact with these storages we use standard networking protocols (http(s))
- No need for us to think of filesystem
- Here since the storage is hosted by someone else there are storage costs involved.
Storage As a Service
- Storage costing dimensions
- Storage size
- disk speed
- Network usage (data transfer costs)
- Other:
- Backups
- Archivals
Other important things to consider
- Difference between GB and GiB
- IOPS => IO per second => unit for measuring disk speeds
