Dot Hill Introduces AssuredSAN Pro 5000 Series and AssuredSAN 4000 Series Tiered Storage
Dot Hill’s new AssuredSAN Pro 5000 Series and AssuredSAN 4000 Series target the midrange and high performance tiered storage array markets. The 5000 Series provides up to three automatic data tiers that analyze and optimize the delivery of priority data. The 4000 Series is built with the same architecture, but is tuned for is customers in media and entertainment, telecommunications, and high performance computing with intensive throughput requirements. Both solutions are designed to integrate with VMware, Citrix XenApp and Microsoft Hyper-V, and provide support for Windows, OS X and Linux environments. Both solutions also feature NEBS Level 3 and MIL STD 810F/G compliance for ground stations, deployable command centers, and video archives.
AssuredSAN Pro 5000 Series Overview
For randomized workloads, an AssuredSAN Pro 5000 system delivers 100,000 IOPS sustained from disk and up to 650,000 IOPS from cache. The 5000 Series also specifies up to 5200 MB/s of sustained sequential read throughput and 3000 MB/s of sustained sequential write performance.
Faster I/O is achieved in part through real-time, autonomic data tiering, which prioritizes data files, volumes or blocks between storage tiers using built-in analysis and data scoring. The AssuredSAN Pro 5000 Series continuously and dynamically identifies hot data and responds by moving information from nearline or enterprise SAS drive tiers to faster SSD tiers.
The AssuredSAN Pro 5000 Series does not require administrators to manage RAID levels, provision LUNs and other management tasks. Its interface brings reports, provisioning, replication, and health monitoring to the web-based Storage Management Console. Dot Hill's RealStor technology includes other capabilities that improve the performance and user experience:
- RealTier technology continuously improves storage responsiveness as hot data is moved to the SSD tier in real time.
- RealThin thin provisioning maximizes usage of existing capacity, allowing IT managers to expand storage as capacity is used.
- RealPool eliminates the need to specify RAID levels and other low-level configuration details.
- RealQuick, the quick RAID rebuild, minimizes recovery time and risk factors with rapid data restoration.
- RealSolid enables an individual LUN to be pinned to the SSD tier
- AssuredRemote remote replication, together with VMware's Site Recovery Manager, provide a complete virtualization failover solution.
AssuredSAN 4000 Series Overview
The 4000 Series shares the same architecture as the 5000 Series plus superior streaming performance for bandwidth-intensive applications. Like the 5000 Series, the 4000 Series offers a theoretical maximum 100,000 IOPS sustained from disk and up to 650,000 IOPS from cache, and will deliver up to 5200 MB/s of sustained sequential read throughput and up to 3000 MB/s of sustained sequential write performance.
With the AssuredSAN 4000 Series, this performance is tuned for customers in media and entertainment, telecommunications, and high performance computing. The 4000 Series leverages Dot Hill’s SimulCache, using redundant RAID controllers to eliminate the performance loss from conventional cache mirroring. A dedicated PCIe bus streamlines write performance, driving faster application throughput.
With four ports per controller for a total of eight ports per system, the Dot Hill AssuredSAN 4000 Series scales up to 192 drives and allows customers to mix HDD and SDD drives in several 2.5-inch and 3.5-inch configurations.
The 4000 Series EcoStor battery-free alternative for cache leverages super capacitors and flash memory that Dot Hill says will outlast conventional batteries by more than four times. The 4000 Series also offers configuration and management via the RAIDar 2.0 web interface.
Pricing and Availability
A Fibre Channel AssuredSAN 4000 Series solution with 12 2 TB drives is expected to start at under $30,000. The 4000 Series is expected to ship by the end of September 2012. A base AssuredSAN Pro 5000 Series solution with 48 drives, with a mixture of 600GB HDDs and 200GB SSDs, starts at $63,200. The 5000 Series is expected to ship in October 2012.
