Better Alternative to Hardware and Software Based RAID
Dot Hill AssuredVRA technology enables client, server, storage and motherboard vendors to integrate RAID technology into their products by leveraging the power of today's multi-core CPUs instead of a dedicated and ROC-based RAID add-in board, helping to reduce hardware, power, cooling and support costs. Basic AssuredVRA and enhanced AssuredVRA products directly support the built-in core logic SATA ports that come as part of these systems, enabling vendors to easily add RAID 0, 1, 5, 10 capability to these otherwise unused built-in SATA controllers, without the need for a more expensive ROC based solution.
The AssuredVRA technology leverages a sophisticated RAID software stack, enabling today's computer systems with both SSD and HDD support to effectively process RAID tasks without compromising performance needed for other operations. Its innovative write-caching engine provides up to three times the performance of competing host software RAID stacks or ROC-based adapter cards. As VRAs are software based, they can easily incorporate other data protection services, such as the n-way mirroring schemes offered as part of the new products, to support simple, transparent and cost-effective system backup and recovery.
