CloudSpeed Extreme™ SATA SSDs are designed specifically for write-intensive application workloads such as, high performance computing (HPC), database logging and database and data warehousing that need the highest levels of performance and reliability. Examples include financial applications and databases associated with workloads that are time-sensitive and produce results that are critical to the businesses they support.
High-performance computing workloads consist of high-volume processing of large datasets which greatly benefit from 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 work more effectively and protect data as it is generated by scale-out applications across the cluster.
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 they roll data forward to the point of failure. In cases of unplanned downtime, databases can be restored to a point beyond the last full, offline back-up, because they preserve the last in-flight transactions.
Database workloads require fast and accurate writes to disk, as well as easy access to the stored data. SanDisk CloudSpeed Extreme SSDs support database workloads, even in virtualized computing environments. This is important because many IT organizations are consolidating database workloads to run on fewer physical servers, resulting in more efficient infrastructures that host business workloads in less data center space, and require less power and cooling. By hosting more virtual machines (VMs) per physical server, customers reduce total cost of ownership (TCO) and increase return on investment (ROI) for new server deployments that have SSDs, compared with hard-disk (HDD) deployments.
(Preliminary specifications subject to change.)
What happens to the data on the SSD if the power is turned off? The CloudSpeed Extreme™ SATA SSD retains the data just as an HDD would.
Is a special enclosure required for the CloudSpeed Extreme SSD? The CloudSpeed Extreme SSD is compatible with any industry standard enclosure that supports a 2.5 inch form factor and SATA interface.
Is any special device driver software required for the CloudSpeed Extreme SSD? The CloudSpeed Extreme SSD requires no special device driver software.
Can the CloudSpeed Extreme SSD be mixed with HDDs or other types of SDDs in the same enclosure? Just as with HDDs, mixing of disk drives with different workload profiles will render unpredictable results. Therefore mixing of devices is not recommended.
Do CloudSpeed Extreme SSDs really increase the performance of servers? Yes, CloudSpeed Extreme SATA 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 CloudSpeed Extreme SSDs have no moving parts, so data is accessed much faster thus reducing server wait time.
Can CloudSpeed Extreme SATA 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.
