Virtual SAN Datastore• Virtual SAN is an object store solution that is presented to vSphere as a file system.

• The object store mounts the volumes from all hosts in a cluster and presents them as a single shared datastore.– Only members of the cluster can access the Virtual SAN datastore– Not all hosts need to contribute storage, but its recommended.

Slash All-Flash Storage Costs With Space Efficiency Features

Erasure Coding (RAID 5/6)• Predictable 50% to 100% increase in effective storage

capacity while maintaining the same protection levels• Independent of workload and dataset• Single parity protection or double parity protection

(failures to tolerate equal 1 or 2)

Space Efficiency features work together to provide up to 10x reduction in dataset size

Up to 7x storage reduction with deduplication and compression

* Actual deduplication and compression storage reduction will vary based on workload and configuration.

Deduplication and Compression• Software-based• Minimal (<5%) CPU and memory resource impact

maintains high VM performance• Optimal efficiency: highly granular 4K block size• Continuous benefits as data grows, more VMs added

32

Deduplication and Compression for Space Efficiency• Nearline deduplication and compression per disk group level.

– Will be called “Space Efficiency”

• Space Efficiency enabled on a cluster level• Deduplicated when de-staging from cache tier to capacity tier

– Fixed block length deduplication (4KB Blocks)

• Compressed after deduplication

Performance of Virtual SAN from StorageReview.com

• Comparable 4-node hardware configurations were tested

• Virtual SAN config was priced at less than half of the competitive system

• VMmark, an accepted industry test, measured how many workloads the clusters could handle– A “tile” is a standardized workload

HCI for Any App, Any ScaleGranular scale up and outBuilt for business critical applications Designing for the future of cloud-native apps ““In the past, we had no

ability to add storage or scale to meet our growing needs. Today with Virtual SAN, I can add more disk on the fly without even thinking about it, and memory upgrades have become a breeze.”

Case Study

“In VSAN, I simply add drives into a chassis anywhere in my system. If I need more space, I buy a simple chassis, and continue to add drives. Much more scalable. There really is not limit to it.” Video Review
