LONGMONT, Colo., April 2, 2015 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp.(Nasdaq:HILL), a trusted supplier of innovative enterprise-class storage systems, today announced new independent lab testing results which validate Dot Hill Ultra48™ AssuredSAN® hybrid storage solutions with RealStor™ 2.0 deliver greater performance with lower latency than competitive offerings that rely on read-cache approaches to prioritizing data, without compromising ease-of-use. The Lab Validation Report, issued by Enterprise Strategy Group (ESG), documents the results of expert, independent, hands-on testing of the Dot Hill AssuredSAN 4000 Series next-generation hybrid solution with a focus on the value of RealStor 2.0 application workload-aware intelligence software and the Ultra48 AssuredSAN high-density storage enclosure. The report confirms that Dot Hill's RealStor 2.0 real-time autonomic tiering features and capabilities far exceed read-cache alternatives from competitors. "IT managers are struggling with the challenges of managing data growth and improving data protection. The increasing use of server virtualization is also a top priority as organizations recognize the opportunity to improve efficiency by consolidating applications on fewer physical servers. In addition, storage-intensive big data and data analytics initiatives are on the rise as organizations look to accelerate business intelligence," said Brian Garrett, vice president of ESG Lab, Enterprise Strategy Group. "The new and improved software capabilities of RealStor 2.0 and the flash-optimized Ultra48 high-density hardware platform cost-effectively address the data growth and performance challenges associated with a wide variety of these applications and associated workloads." Testing Conclusions After testing RealStor 2.0 and its range of associated services, ESG Lab drew a number of conclusions including:
- RealStor 2.0 with RealPool™ and RealThin™ increased the efficiency and ease of managing a cost-effective hybrid mix of solid-state drive (SSD) and hard disk drive (HDD) storage.
- RealTier™ started to increase performance with a hybrid mix of SSD and HDD in a matter of minutes for an OLTP database workload.
- RealCache™ with SSD increased performance for a read-intensive database workload in a matter of seconds.
- RealQuick™ reduced RAID group rebuild times by 14.6x for a volume that was 10 percent full compared with a traditional full-volume rebuild.
- The new and improved RealStor 2.0 management interface was used to configure an AssuredSAN 4004 Series from scratch in five minutes and 26 mouse clicks.
- ESG Lab confirmed that the fully redundant and field-serviceable Ultra48 Platform is highly available as it rode through a barrage of simulated hardware failures.
"ESG Lab has validated our own findings by providing extensive, thorough third-party performance testing of Dot Hill RealStor 2.0 and our Ultra48 AssuredSAN hybrid storage system," said Bill Wuertz, senior vice president, products and solutions, Dot Hill. "With high-performance controllers, redundant design, and RealStor 2.0 software included standard, Dot Hill AssuredSAN ultra-density hybrid storage arrays provide optimal hardware platforms for virtualized server environments, transaction-intensive applications or any environment that calls for a storage system that can respond in real time to constantly changing workloads."Simply Smart and Efficient As the ESG Lab report notes, RealStor 2.0 was designed with the goal of improving the efficiency, manageability, and performance of pools of storage. "Pools of HDDs, SSDs and a hybrid mix of both are supported. After configuring storage into one or more autonomic pools, RealStor 2.0 kicks in and works automatically as it delivers a simply powerful range of smart and efficient storage services," states the report. Those services include:
- RealTier, which improves performance and reduces costs. Frequently accessed 4MB chunks of application data are moved to a higher performing tier (e.g., SSD) for faster performance, and infrequently accessed chunks are moved to a lower cost tier (e.g., near-line SAS) for reduced costs.
- RealPool, which simplifies the definition and management of tiered pools of storage with a powerful, yet simple-to-manage, storage virtualization layer.
- RealSnap™, which provides zero-impact data copies for quick and easy recovery and test development. Read-only and writeable snapshots are supported with redirect-on-write technology and no need for zero block recovery.
- RealQuick, which reduces the risk of data loss after a drive failure with fast RAID rebuilds. Instead of rebuilding an entire RAID group, only the capacity that has been allocated to storage volumes is rebuilt to restore data protection more quickly.
- RealThin, which reduces the cost of storage capacity with thin provisioning. Instead of reserving and consuming storage when host volumes are created, thin provisioning consumes capacity as needed by applications.
- RealCache, which provides a quick real-time performance boost for business-critical applications with SSD configured as a caching layer for frequently accessed read data.
