 +===== Возможности =====
 +
 +  * Дедупликация блоком 4к
 +  * Компрессия блоков 4к
 +  * Протестирована работа XFS и ext4. Рекомендуется использовать XFS.
 +  * Основная задача оптимизация Flash СХД
 +  * Данные которые хорошо дедуплицируются (от 2 до 6 раз) (по информации вендора):
 +    * Резервные копии (если они выровнены по блоку 4к)
 +    * Виртуальные машины
 +    * Образы контейнеров
 +    * Домашние папки
 +
 +==== 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
