Testing Confirms 'Wicked Fast' Performance
Performance testing of AssuredSAN Pro 5000 Series quantified the benefits of tiering in real time. ESG Lab tested an industry-standard workload that simulates the activity of a typical OLTP database application in a pool with sixty 600GB RAID-10 RPM hard drives and eight 400GB RAID-1 solid-state drives. ESG Lab showed that real-time tiering kicked in and started migrating frequently accessed data to solid-state within minutes and aggregate performance increased approximately 2.5 times over the course of the next 14 hours.
Performance testing of the AssuredSAN 4000 Series measured the raw performance of the underlying hardware, emulating a typical Microsoft Exchange 2010 user in a VMware ESX 5.1 virtual server environment with a mailbox size of 200MB and target I/O rate of 0.13 IOPS per mailbox. ESG Lab reported that an impressive peak of 52,000 mailboxes was supported as the number of virtual machines running in parallel scaled from one to four. In each case, testing recorded average database response time under the Microsoft recommended limit of 20 milliseconds.
"Many storage vendors make grandiose claims about their products' performance, but few put their products under the microscope to undergo third-party performance evaluation," said Jim Jonez, senior director of marketing, Dot Hill. "This ESG Lab Validation Report offers independent validation of the performance and simplicity of Dot Hill's AssuredSAN Pro 5000 and AssuredSAN 4000 storage systems and the associated real-world benefits for midmarket organizations. These new products deliver demonstrated high availability with best-in-class price/performance. And the Pro 5000 delivers the world's most responsive storage with real-time tiering and a simplified interface for improved operational efficiency.""As IT managers face the challenges of cost, complexity and performance, we believe our expanded AssuredSAN portfolio is extremely well-equipped to meet the needs of a broad range of customers from entry-level to the midrange, delivering up to 99.999 percent data availability across the board."
