Lightning Read-Intensive SAS SSDs offer solid cost-to-performance benefits for applications that demand low latency read speeds and greater bandwidth for high-speed storage and server environments. These SSDs use a parallel processing architecture that provides predictable performance, low response times under peak conditions, and proven endurance for superior value. These SSDs are ideal for mission critical, 24/7 read-intensive applications workloads with a 90/10 read/write mix.
When flash storage is used with management software, data retrieval is optimized to match the ebbs and peaks of workload demands. Providing performance to meet rising demands is key to maintaining quality of service (QoS) for delivering data to end users.
Flash storage accelerates the Internet traffic that enters the data center for processing and helps to overcome I/O bottlenecks. In addition to accelerating Web traffic for enterprise data centers, SSDs support fast processing by cloud service providers.
Flash storage works with large datasets that are generated for movies, videos, and music, and are distributed via broadcast and the Internet. These products must support high data transfer rates, faster animation rendering, and image-painting. This enhances performance with near-real-time results, improving the customer experience for those viewing the content.
Video on Demand (VOD) is accessed by PCs , smartphones, and entertainment HD-TVs or consoles. It allows users to access video from virtually any device instantly; and it gives media companies the ability to serve thousands of users simultaneously.
What happens to the data on the SSD if the power is turned off? The Lightning Read Intensive SSD retains the data just as an HDD would.
Is a special enclosure required for the Lightning Read Intensive SSD? The Lightning Read Intensive SSD is compatible with any industry standard enclosure that supports a 2.5 inch form factor and 6 Gb/Sec SAS interface.
Is any special device driver software required for the Lightning Read Intensive SSD? The Lightning Read Intensive SSD requires no special device driver software.
Can the Lightning Read Intensive SSD be deployed with HDD’s or other types of SDDs in the same enclosure? Just as with HDD’s, mixing of disk drives with different workload profiles will render unpredictable results. Therefore mixing of devices is not recommended.
When deploying Lightning Read Intensive SSDs, do all HDDs have to be eliminated from an enterprise? No. A desired number of existing HDDs can be retained so long as they reside in a different disk shelf than the SanDisk Lightning Read Intensive SSDs.
Is the Lightning Read Intensive SSD reliable? The Lightning Read Intensive SSD is extremely reliable with a reliability rate of one in 1016 bits read, which meets the requirements specified by the JEDEC JESD218 standard, which calls out for a minimal UBER of one in 1016 bits read for Enterprise‐class SSDs.
Do Lightning Read Intensive SSDs really increase the performance of servers? Yes. Lightning Read Intensive SSDs can increase a server’s performance by reducing a server’s I/O wait time to get data for processing. SAS HDDs have an average wait time of half a disk revolution before the read heads are positioned over the desired data. The SanDisk Lightning Read Intensive SSDs have no moving parts, so data is accessed much faster thus reducing server wait time.
Can Lightning Read Intensive SSDs really greatly consolidate/reduce storage footprint? Yes. With HDDs performance is directly related to spindle count, so the more HDD spindles, the greater the performance. Traditionally, in the HDD environment short stroking has been used to obtain the level of performance required – short stroking is the technique of greatly over-provisioning HDD spindles to obtain a desired performance level while only requiring a fraction of the over-provisioned storage capacity. One SanDisk Lightning Read Intensive SSD can achieve up to 78K Read IOPS which would take several full HDD storage shelves to match the number of IOPS. So in essence one SanDisk Lightning Read Intensive SSD can replace scores of HDDs, greatly reducing footprint and energy consumption.
How are Lightning Read Intensive SSDs designed for Read Intensive workloads such as Front-end Web Servers, Media Streaming, Video on Demand (VOD), Cloud Service Providers and Web Applications? The key to achieving increased data and system performance is in understanding the specific application workload. The Lightning Read Intensive-Use 6Gb/s (SAS) SSDs provide an I/O pattern designed around frequent reads for application workloads with a 90/10 read/Write workload.
What areas can greatly benefit deployment of Lightning Read Intensive SSDs? Lightning Read Intensive SSDs have been designed with an advanced innovative controller that uses a parallel processing architecture with single firmware binary for superior reliability. This design delivers the industry’s leading sustained performance with the most predictable performance profile across a wide range of workloads. Areas involving Front-end Web Servers, Media Streaming, Virtual Tape Libraries (VTL), Video on Demand (VOD), Cloud Service Providers, Web Applications, and File Servers can greatly increase performance and reduce costs through the use of the Lightning Read Intensive SSD.
