Lightning Ascend™ Gen. II SAS SSDs offer superior reliability with high speed data transfer rates where quick access to data is essential. Available in 19nm eMLC, these SSDs are designed for mixed-use applications such as on-line transaction processing (OLTP) databases, email/messaging, e-commerce, virtual desktop infrastructure (VDI), and collaboration with a typical workload comprised of a 70/30 read/write mix.
This next generation Lightning ® SSD offers a feature-rich robust design combined with SanDisk’s innovative parallel processing architecture to deliver full data path protection (supports T10-DIF), temperature based power control, SED instant secure erase, an MTBF of 2.5 million hours**MTBF – Mean Time Between Failures based on parts stress analysis. and power fail protection.
Collaborative workloads include email, messaging, and groupware. These workloads, such as Microsoft® SharePoint, Microsoft Exchange®, and Linux-based groupware, allow end-users to share content and coordinate with others. SanDisk flash memory promotes ease-of-use by reducing latency and smoothing out the customer experience—even if the amount of end-user updates ebbs and peaks throughout the work day.
Email messages have become essential parts of the official “records” for businesses and organizations. They must be maintained, with accuracy, for legal and compliance purposes. In everyday business, emails are the “glue” of daily business, allowing teams in many locations to collaborate on projects. Flash storage delivers high-volume email updates safely and securely to their destinations, supporting the daily flow of business processes.
Lightning Ascend Gen. II SAS SSDs support hundreds of individual end-user “sessions” on a server instead of storing those sessions on local PCs. This approach protects enterprise data and ensures business continuity. Lightning Ascend Gen. II SAS SSDs avoid boot storms which often slow VDI response times when large numbers of end-users start up their personal-desktop applications in a VDI environment.
What happens to the data on the SSD if the power is turned off ? The Lightning Ascend Gen. II SAS SSD retains the data just as an HDD would.
Is a special enclosure required for the SanDisk Lightning Ascend Gen. II SAS SSD ? The Lightning Ascend Gen. II SSD is compatible with any industry standard enclosure that supports a 2.5 inch form factor and any 12Gb/s or 6Gb/s SAS interface.
Is any special device driver software required for the Lightning Ascend Gen. II SAS SSD ? The Lightning Ascend Gen. II SAS SSD requires no special device driver software.
Can the Lightning Ascend Gen. II SAS 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.
Do Lightning Ascend Gen. II SAS SSDs really increase the performance of servers ? Yes, Lightning Ascend Gen. II SAS 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 Ascend Gen. II SAS SSDs have no moving parts, so data is accessed much faster thus reducing server wait time.
Can Lightning Ascend Gen. II SAS SSDs 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.
