Technical Activities Whitepapers

The following are technical whitepapers produced by various SNIA Technical Work Groups.

Architectural Model for Data Integrity

This document describes a model for how data integrity can be protected between an Application client and a storage device. If all nodes in an implementation follow this model then there will be end-to-end data protection for the following class of data integrity errors: silent data corruption, wrong address on device and buffer corruption.

Hypervisor Storage Interfaces for Storage Optimization White Paper

To assist with the management and operation of Hypervisor Storage, the SNIA HSI TWG is clarifying the use of, extending, and/or developing standard Hypervisor Storage Interfaces for storage interactions with hypervisors. These interfaces enable the hypervisor to offload certain storage intensive tasks to the underlying storage systems to achieve performance and functional improvements.

It is the purpose of this document to describe use cases where it is desirable to have the storage array perform offload operations and/or have some visibility into virtual disk constructs while maintaining the necessary and appropriate abstractions and isolation.

The first revision of this document focuses on optimizing copy operations and space reclamation operations in block storage environments.
