Storage¶
Six storage services from blazing NVMe block to cold archive object — every byte resident in Bangladesh.
-
Hyper-converged NVMe block, the default for VMs.
-
Block Storage (Provisioned IOPS, NetApp)
NetApp-backed block with guaranteed IOPS for OLTP databases.
-
S3-compatible API. Standard tier.
-
Cold tier for long retention, lower cost.
-
Shared filesystems — NFSv4, SMB 3.
-
Standalone snapshot repository, independent of source volumes.
Pick the right tier¶
| Workload | Pick |
|---|---|
| Boot disks, general VMs | Block Storage (NVMe HCI) |
| OLTP database, hot transactional store | Block Storage (Provisioned IOPS) |
| Application objects, media, backups | Object Storage (S3) |
| Compliance archive, regulatory retention | Object Storage (Archive) + Object Lock |
| Lift-and-shift legacy with shared FS | File Storage (NFS or SMB) |
| Cross-VM scratch | File Storage (NFS) or Block + clustered FS |
Encryption at rest¶
All Cloud Digit storage is encrypted at rest with AES-256 using cluster-managed keys by default. Customer-managed keys (BYOK) for block and object are on the roadmap; see Secrets Management.
Durability¶
| Service | Durability target | Replication |
|---|---|---|
| Block (NVMe HCI) | 99.9999% | 3-copy (or EC 4+2) within region |
| Block (Provisioned) | 99.9999% | NetApp HA pair + sync mirror |
| Object (S3 Standard) | 99.999999999% (11 nines) | Erasure-coded across 3 fault zones |
| Object (Archive) | 99.99999999% (10 nines) | Erasure-coded across 3 fault zones |
| File (NFS / SMB) | 99.9999% | 3-copy or EC |
| Snapshot | 99.99999999% (10 nines) | Object-storage backed |
