SS7210 also provides a very easy-to-use Web-based utility for analyzing the system performance. Managing NAS storage, analyzing performance, and configuration issues can be done with a simple and very powerful web-based interface. The user can customize a worksheet, add/remove performance real-time statistics, and export the data to external csv files for records and analysis.

Performance is easy to get simply out-of-the-box. The Sun Storage 7210 Unified Storage Array in striped configuration can stream more than 735 MB/sec (mirrored 752 MB/sec) video to deliver 5,880 videos randomly selected from 54,000 1 Mb/s streaming rate video files (in FLV format).

• This steaming rate of 735 MB/sec is the equivalent to a single layer DVD (4.7GB) in 6.4 seconds.
• The Sun Storage 7210 Unified Storage Array can store 91,500 hours of 1 Mb/s streams using a striped configuration.
• The Sun Storage 7210 Unified Storage Array can hold 43,775 hours of 1 Mb/s videos.
• 1 TB of data can be streamed in less than 23 minutes at 735 MB/sec.

Key Technical Points

Ease of Management with the Sun Storage 7000 Unified Storage System

The Sun Storage 7000 Unified Storage System is the first open storage appliance that radically simplifies the way you manage your data that makes it easy to analyze and optimize your storage system.

It uses simple to use graphical tools and SolarisTM DTrace analytics software provide real time visibility throughout the entire data path. The browser interface provides an intuitive environment for administration tasks, visualizing concepts and analyzing performance data.

DTrace analytics capabilities include real time statistical graphs to help locate and isolate problems, and optimize storage performance and capacity utilization. DTrace provides pervasive observability to accelerate application development and optimization of Apache/MySQL/PHP (AMP) and MySQL/Apache/Ruby/Solaris (MARS) stacks.

Benchmark Description

Video Streaming Process

There are two different types of video delivery, Video On Demand (VOD) and Real Time Broadcasting. Video on demand can be delivered via file download or streaming. The size of a high-quality 1-hour 1 Mb/s video is 450 MB. Typical internet video streams are delivered at 300 Kb/s.

Each edge node of a Content Delivery Network (CDN) requires large amounts of storage. Real-time broadcasting does not require local storage, but recording and rebroadcasting is a very common practice (which do have large storage requirements).

The Sun Storage 7210 Unified Storage Array is well suited to be used as an edge node for video on demand purposes.

Twenty-six Wowza Media Servers and SS7210 are set up as an edge node for video streaming. SS7210 is populated with 54,000 videos, each video is a 1Mb/s stream in FLV format. The test uses 26 load generators to simulate 5,880 concurrent streaming sessions. Each session mimics a player that randomly selects a video out of the 54,000 videos, plays the video delivered by one of the media servers for 45 minutes, stops playing and repeats the same scenario.

Disclosure Statement:

Sun Microsystem generated results of typical Video on Demand requirements. Results reported 10/7/08 using solutions from www.wowzamedia.com.
