2 Testing Result Significant Performance Improvement: up to +137% with only 10 ~15% cost premium using a 3Gb/s Environment with Updated 6Gb/s Controller Average MBps LSI 3Gb/s SAS Controller with eight units of Hitachi 2TB 3Gb/s SATA LSI 6Gb/s SAS Controller with eight units of Hitachi 2TB 3Gb/s SATA LSI 3Gb/s SAS Controller with eight units of Hitachi 2TB 3Gb/s SATA LSI 6Gb/s SAS Controller with eight units of Hitachi 2TB 3Gb/s SATA Test 1 Test 2 Test 3 Test 4 Test 5 Average MB/s MB/s MB/s MB/s MB/s MB/s MB/s MB/s MB/s MB/s MB/s MB/s * Tips: This test tends to show performance delta only between 3G and 6G based systems. To achieve maximum sustained RAID 6G controller throughput, 12 drives or more is suggested to see performance scale beyond up to MBps. 2

3 Benefits Premium vs. Performance Using current 3Gb/s Hard Disk Drives, you can receive the performance benefits that LSI technology has to offer with 6Gb/s SATA+SAS storage adapter options. And, for a very affordable price (10~15% premium) to gain significant performance benefits (+137% in this test). High Performance Scalability LSI 6Gb/s SATA+ SAS technologies offer much higher overall throughput to your host system and allow larger amounts of hard drives to be used through a single controller without a performance bottleneck. Leveraging large arrays through a single controller minimizes hardware costs for storage. Data Security & Availability The latest MegaRAID DE series controllers support hardware based encryption with SED hard drives. This advanced feature for data at rest protection is now available to system integrators, it allows robust security using LSI SafeStore encryption as well as the instant erase feature for quick drive repurposing ideal for data center customers Offer the latest technology for your customers Switching to LSI 6Gb/s technologies for your systems gives you more value and more performance than with other vendors. 3

4 6 Reasons to Adopt LSI 6Gb/s SATA and SAS Technologies More Performance & Capacity More video streams RAID 5 Seq Reads improved by 70% 1 Connect more HDDs to a single controller More database transactions Iometer OLTP improved by 50% Faster backups RAID 5 Seq Writes improved by 190% Features and Usability New Spread Spectrum Clocking (SSC), longer cables, Decision Feedback Equalization (DFE), Self configuring adapters 2 Intuitive RAID management utility available Improved Usability in MegaRAID Storage Manager (MSM) Data Security & Availability SafeStore Encryption Services for self encrypting drives (SEDs) helps secure a drive s data from unauthorized access. Instant Secure Erase erases SEDs in less than a second, enabling secure drive returns or reuse. 3 4 Local Key management locks and secures SEDs in the event of theft or a data breach. Easy to Deploy Adopt any 6Gb/s SATA+SAS product for 3Gb/s systems and scale for future migration to 6Gb/s Ecosystems. 6Gb/s or 3Gb/s, SATA or SAS, HDDs, SEDs, or SSDs, 7.2K, 10K, 15K RPM Use them all without compromising functionality. 5 6 Minimal downtime as well as simple installation and configuration. Quick to provide customer benefits of 6Gb/s for 3Gb/s HDDs. Build and deploy systems easier than ever. Flexibility & Scalability High ROI & More Green LSI 6Gb/s products represent a higher value/$, efficient and affordable upgrade from today s 3Gb/s systems. More efficient energy utilization, to include improved power profiles. 4

8 Conclusion LSI 6Gb/s SATA+SAS storage adapters are backwards compatible with 3Gb/s SATA and SAS HDDs. They offer a boost of performance for the existing 3Gb/s based systems and can offer remarkable performance using 6Gb/s systems. In this test, we only used 8 hard disk drives to test the single LSI i controller card, and the result is impressive with up to a 137% performance improvement. You can maximize the performance up to 2500MB/s in RAID 5 and 6 and up to 3000MB/s in RAID 0if more drives are attached using 6G expanders. By investing into a 6Gb/s ecosystem, the benefits greatly outweigh the costs as the products deliver superior I/O performance which allows you to support more applications and users on a similar system design. The testing report of LSI 6Gb/s SATA+SAS with 6Gb/s Hard Disk Drives will be released by the Testing Labs of Microland Electronics Corp. in Q To learn more how to optimize performance with LSI 6Gb/s MegaRAID Technologies, please visit: 8

9 LSI 6Gb/s- Ideal Solutions for Your Applications Cloud Computing: Companies who offer highly scalable and virtual resources need reliable and high performing solutions. They will benefit from being able to deliver more data in and out of the cloud. Database Servers: Companies who build and maintain servers that run database programs can benefit from migration to 6Gb/s. They can boost the retrieval of specific information from their massive set of data. High Performance Computing (HPC): Clustered systems with massive storage require the reliability of protected data while supporting more nodes by offering higher throughput. S Camera (Video Surveillance): The most sophisticated video surveillance applications require increased through put to support higher resolution pt used by today s technology. These powerful systems need performance, capacity, reliability and data security. Web Servers: A large number of users access these storage servers at all times of the day. Always on access is critical, along with speed of reads and writes. Top of the line performing systems is a business requirement to support the users that rely on these systems. 9
