Enterprise Flash Technology Solution Brief

  1. 1. Enterprise Flash Technology Revolutionizing enterprise storage infrastructure Businesses increasingly rely on datacenters To compensate, IT managers typically add to provide access to services, applications, more external devices and DRAM to help and data. As demand rises and applications speed throughput. More DRAM lets systems grow in complexity, datacenter infrastructure store working sets in memory to avoid disk must provide massive capacity and fast access latency, and adding disk spindles can help to information in order to keep pace with increase throughput by letting I/O operations business priorities. Today companies can be performed in parallel. However, the result add storage capacity easily by augmenting is an expensive infrastructure that is difficult infrastructure with additional hard disk drives to manage and cannot be counted on to keep and arrays. Unfortunately, the devices that pace with throughput demands. provide the highest capacity fail to provide the I/O performance needed to keep systems Flash technology moves to the enterprise supplied with the data for processing — and Originally developed in the 1980s, Flash inflate storage infrastructure costs. technology is low-cost, non-volatile computer Enterprise Flash technology has the potential to provide orders of magnitude improvement in storage infrastructure economics and performance.

  2. 2. 2 Enterprise Flash Technology Enterprise solid state devices Solid state devices (SSDs) based on Flash Low power consumption With energy costs rising, power has become With fast read and technology are emerging as a new enterprise- class storage option. With fast read and write the dominant factor in high-scale hardware decisions. Hard disk drives draw significant write performance performance, a compelling price point, and amounts of power to operate the motor and and a compelling incredibly low power requirements, devices spin media. In contrast, the use of efficient based on Flash memory are poised to disrupt Flash memory and a lack of motors and price point, Flash the industry. other mechanical parts result in enterprise SSDs consuming a fraction of the power technology is poised High performance to meet demand of conventional hard disk drives. In fact, Keeping systems supplied with data is enterprise SSDs use only 5% of the power to disrupt the key to overall datacenter performance. Flash technology completes operations in used by hard disk drives when idle, and as little as 15% when performing operations. industry. microseconds, placing it between hard disk drives (milliseconds) and random access Very low cost per gigabyte and per IOPS memory (nanoseconds) for access time. In today’s challenged economy, creating cost- Because Flash technology contains no moving effective storage infrastructure is paramount. Since hard disk drives must be powered on to parts, it avoids the seek times and rotational While Flash devices are more expensive per be available, the low power consumption of latencies associated with traditional hard disk gigabyte than a comparable disk drive, Flash enterprise SSDs makes them a smart choice drives. As a result, data transfer throughput memory costs are dropping significantly year for datacenters looking to reduce operating to and from solid state storage media is over year. In addition, as electricity costs rise costs. While a gigabyte of mechanical disk faster than electro-mechanical disk drives can and Flash memory costs decrease, the relative costs less than a gigabyte of Flash memory, provide — with enterprise SSDs providing tens cost per available gigabyte and cost per IOPS the fact that Flash memory outperforms hard of thousands of IOPS compared to hundreds of Flash memory improves. For example, hard disk storage by at least an order of magnitude of IOPS for hard disk drives (Figure 1). Unlike disk drives cost approximately $1.25/IOPS, in reading and writing data makes the cost DRAM, enterprise SSDs do not need to reload compared to only $0.02/IOPS for enterprise per gigabyte of Flash devices exceptionally cached data, helping services to resume SSDs. low. faster.

  3. 3. 3 Enterprise Flash Technology Creating a new storage tier Other uses for Flash devices “SSDs can be a kind of super-cache Applications running on current multicore, Flash devices can be used in other ways to multisocket servers are increasingly held help datacenters improve performance and where you store data when it needs back by slow storage systems. Technological reduce operational expenses. Flash devices advancements are changing the way storage can be: to go fast. But companies are also devices can be used to rebalance systems and storage and create optimized solutions. While • Used as a boot disk replacement to save on interested in SSDs as primary storage hard disk drives provide the capacity needed space and power consumption for applications that require high to handle large amounts of I/O, they are slow • Used to replace time-consuming disk access to perform. On the other hand, enterprise protocols with more efficient memory-to- performance all the time. The bonus — SSDs provide required I/O throughput, memory transfers and help scale to many yet cannot provide the capacity needed at millions of IOPS SSDs consume about one-fifth the competitive price points. Continuing the promise of open storage power of ordinary disk drives.” The right approach combines the strengths As enterprises struggle to cope with the of both technologies. Flash devices can be phenomenal rise in digital data volumes and Graham Lovell placed in a new storage hierarchy to assist budget pressures, they are looking for storage Senior Director of Open Storage, Sun Microsystems disk drives by holding frequently accessed architectures that provide greater flexibility data to minimize the impact of disk latencies and better economics. For years, enterprises and improve application performance. With utilized servers and storage systems that were the addition of Flash storage, applications closed, proprietary, and expensive. access data stored on a combination of enterprise SSDs and hard disk drives, resulting Just as open systems changed high-scale in more balanced I/O throughput (Figure 2). computing with affordable architectures, open storage is revolutionizing data management Caching and the hybrid storage pool with innovation and choice. By delivering Integrating Flash devices into the storage industry-standard hardware and open source hierarchy as a disk cache can result in software, Sun provides creative technologies significant performance gains for I/O for developing and deploying new storage intensive workloads, without the need to faster. modify applications. In such an environment, Flash devices are used to store actively used data, making the entire storage infrastructure Capacity Performance Capacity appear as fast as Flash storage to applications.
