Processor Architectures
One or more processors implementing the Intel 64 instruction set are required: that is, a processor of the AMD64 or Intel 64 architecture.
RAM
Each VDO volume has two distinct memory requirements:
The VDO module requires 370 MB plus an additional 268 MB per each 1 TB of physical storage managed.
The Universal Deduplication Service (UDS) index requires a minimum of 250 MB of DRAM, which is also the default amount that deduplication uses. For details on the memory usage of UDS, see Section 29.2.1, “UDS Index Memory Requirements”.
The following configurations are not supported
VDO on top of VDO volumes: storage → VDO → LVM → VDO
VDO on top of LVM Snapshots
VDO on top of LVM Cache
VDO on top of the loopback device
VDO on top of LVM Thin Provisioning
Encrypted volumes on top of VDO: storage → VDO → DM-Crypt
Partitions on a VDO volume: fdisk, parted, and similar partitions
RAID (LVM, MD, or any other type) on top of a VDO volume
