The Sun Storage F5100 flash array redefines storage performance and efficiency with an incredible 1.6 million read and 1.2 million write IOPS in just 1.75 inches of rack space. It sets new benchmark records for IOPS per dollar, IOPS per watt, and IOPS per space. I/O-intensive database applications with heavy I/O read and 4 K block-aligned write workloads can take advantage of the Sun Storage F5100 flash array to accelerate their performance, improve response times, and increase transactional scalability, while also reducing power and space costs.
The Sun Storage F5100 flash array offers a breakthrough in storage economics with industry-leading price/performance, power/ performance, and space/performance efficiency. By using the Sun Storage F5100 flash array to address your performance needs, you can supplant costly and inefficient 15 K rpm disk drives, which drive up power and storage costs. This can help you significantly reduce both storage costs and operating costs, resulting in much-lower TCO.
The Sun Storage F5100 flash array provides a very high level of reliability with an all-solid-state durable design consisting of 80 nonvolatile enterprise-class single-level cell (SLC) flash modules, each with MTBF exceeding that of enterprise disk drives. The system uses sophisticated wear leveling, advanced bad block mapping, and enhanced write endurance to help ensure the highest level of reliability and longevity. Redundant power and cooling helps reduce the risk of downtime, and integrated super capacitors help prevent interruptions in write operations should a power failure occur. Host-based mirroring can also be used for mirroring internal domains or individual flash arrays.
The flash array takes advantage of data integrity features in the Oracle Solaris Zettabyte File System (ZFS), including ZFS RAID, automatic data integrity checking, and correction with block-level checksums. When a corrupt block is identified, self-healing features in Oracle Solaris ZFS will direct another copy to be written as an automatic repair, thus helping to prevent silent data corruption.
Today more and more applications, especially databases, are being choked by disk drives that can no longer keep up with CPU performance, causing latencies and I/O bottlenecks. The traditional approach of using large numbers of mechanical disk drives to address growing storage performance needs can greatly increase power, cooling, and space costs. IT managers are looking for more-cost-effective and highly scalable storage solutions that can quickly accelerate application performance while also reducing operating costs.
This effectively multiplies I/O throughput by enabling read and write operations to take advantage of multiple spinning disks. However, it also results in inefficiencies, because the need for performance results in configurations with more disk drives than would be warranted based solely on capacity requirements. The high power requirements of 15 K rpm drives and the poor space use of partially filled disks also result in unnecessary datacenter power, space, and capital costs.
Reliability characteristics of enterprise-class flash and SSDs have also improved, yielding mean time between failures (MTBF) ratings that exceed those of HDDs. Like HDDs, enterprise SSDs also support bad block management, wear leveling, and error correction codes to foster the highest level of data integrity and reduce service downtime. The solid-state nature of flash allows enterprise SSDs to withstand significantly higher shock and vibrations than HDDs.
