Featuring an I/O pattern designed to support applications with heavy write workloads, SanDisk Lightning Write-Intensive SAS SSDs are optimized for data management, endurance for high-speed storage, and server environments. These solid state drives (SSDs) use a parallel processing architecture that provides predictable performance, low response times, and proven endurance for superior reliability. They are ideal for mission critical, 24/7 application workloads with a 50/50 read/write mix.
Database logging is a write-intensive workload that allows customers to recover from failures by helping to connect primary and secondary databases. These database logs keep records of all database changes as transactions are updated, and, in cases of downtime, they roll data forward through the point of failure. In cases of unplanned downtime, databases can be restored to a point beyond the last full, offline back-up, due to flash storage’s non-volatile memory, which preserves the last transactions prior to the downtime.
End-to-end supply chain workloads support global businesses, where any interruption in the updates to centralized databases could mean a real-time interruption in business processes. The ERP applications feed a never-ending series of updates to the databases, or data warehouses, that hold “the single version of the truth” for the entire corporation. That’s why it’s so important to support write-intensive workloads with high-performance systems with non-volatile solid-state storage (SSDs) that protect vital data, even in the event of a temporary power failure somewhere along the worldwide supply chain.
High-performance computing workloads consist of high-volume processing of large datasets, which are greatly benefited by using flash technology. HPC includes engineering and data-intensive workloads like seismic analysis, oil and gas exploration, weather forecasting, and market simulations. Flash storage SSDs help each server’s application in an HPC cluster to work more effectively – and to protect data as it is generated by scale-out applications across the cluster.
Lightning Write-Intensive SAS SSDs support creation of unending streams of video, images, and audio data for entertainment, informational, and recording purposes. For most of these workloads, accurate and rapid delivery is important to preserving the customer experience. For others, accurate delivery is vital to maintaining data integrity, both for recording and archival purposes.
What happens to the data on the SSD if the power is turned off? The Lightning Write Intensive SSD retains the data just as an HDD would.
Is a special enclosure required for the SanDisk Lightning Write intensive SSD? The Lightning Write 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 Write Intensive SSD? The Lightning Write intensive SSD requires no special device driver software.
Can the Lightning Write Intensive SSD be Write intensive with HDD’s or other types of SDDs in the same enclosure? Just as with HDD’s, mixing of different disk drives will render unpredictable results. Therefore mixing of devices is not recommended nor supported.
When deploying Lightning Write 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 Lightning Write Intensive SSDs.
Is the Lightning Write Intensive SSD reliable? The Lightning Write Intensive SSD is extremely reliable with a reliability rate of one in 1017 bits read, which is 10 times greater than 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 Write Intensive SSDs really increase the performance of servers? Yes. Lightning Write 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 Lightning Write Intensive SSDs have no moving parts, so data is accessed much faster thus reducing server wait time.p>
Can Lightning Write 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 Lightning Write Intensive SSD can achieve up to 118K Read IOPS which would take several full HDD storage shelves to match the number of IOPS. So in essence one Lightning Write Intensive SSD can replace hundreds of HDDs, greatly reducing footprint and energy consumption.
How are Lightning Write Intensive SSDs designed for write-intensive workloads such as On-Line Transaction Processing (OLTP) Databases, Infrastructure, E-mail/Messaging, Virtual Desktop, and Collaboration? The key to achieving increased data and system performance is in understanding the specific application workload. The Lightning Write Intensive-Use 6Gb/s (SAS) SSDs provide an I/O pattern designed around frequent writes for application workloads with a 50/50 read/Write workload.
What areas can greatly benefit deployment of Lightning Write Intensive SSDs? Lightning Write Intensive SSDs have been designed to meet demanding, mission critical, 24/7 applications. Workloads involving Data Warehousing, High Performance Computing (Oil and Gas, Life Sciences, Aerospace, Engineering, etc.) Media Editing, Analytics, and Database Logging can greatly increase performance and reduce costs through the use of the Lightning Write Intensive SSD.
