Enterprise users of Solid State Drives (SSD) have become increasingly vigilant about the health and longevity of the memory within their servers.
How to deal with servers memory’s endurance
There is a growing awareness among many datacentres operating commercially critical systems that the benefits of the fast speeds delivered by flash memory also has a ‘dark side’ that needs to be managed. At a recent launch of their new enterprise range of high performance SSDs, Integral Memory has called for greater awareness amongst corporate users and value added resellers to choose the right SSD drive for the purpose.
New generations of ever faster SSDs have demanded more from the flash architecture that delivers data at blistering speeds. However it is a critical mistake to use mainstream SSD products as “drop in” replacements for obsolete HDD drives. Users must specify SSD units that match the application the server is delivering. Failure to install sufficiently robust drives will lead to down-time, extra maintenance costs and ultimately creating a data loss ‘time bomb’ at the centre of a server installation.
“There is a growing realisation about this issue among our customers, yet there are many datacentre managers that seem unaware of the key specifications required of an SSD that will ensure against endurance issues” says Samik Halai, Senior Product Manager at Integral Memory. “The ideal product requires a balance between key factors of bandwidth, performance and latency in order to cope with intensive read/write workloads.”
An awareness of the quantity of data to be written is essential to build a data server that is resilient. Typically, these performance issues are expressed in terms of drive write per day (DWPD) or terabytes written (TBW) over the expected lifetime of a drive. However these guideline can be difficult to apply as a benchmark to the ever changing demands on a corporate datacentre. Essentially, the use of mainstream SSDs undermines not only the endurance but also the consistent performance requirements of a datacentre due to the low latency or lag in the data write operations (IOPS) of a commodity drive that is destined for the consumer market.
Integral Memory’s solution has been to launch a two-tier range of products that are both designed to perform under high, yet differing intensities. The higher tier Enterprise 1 SSD is a premium SSD with super-high endurance, geared for applications within mixed workload duties such as online transaction processing, as a drive within an email server and high performance cloud and data warehousing. The more cost-effective, entry-level Enterprise 2 SSD has been developed for servers that operate under high read-intensive workloads, suitable for video on demand, content streaming servers and webservers.
“By stating the application suitability on the side of the box – we hope to demystify the endurance issue for our customers and provide peace of mind for datacentre managers” commented Samik Halai. “These drives with reduced latencies and sustained IOPS are also covered by a 3 year warranty to give ultimate re-assurance to datacentre managers”.
The Integral Enterprise SSD range are SATA 6Gpbs and are available as E1 (for mixed workload applications) in 120, 240, 480 and 960 gigabytes. The E2 range (for read intensive applications) is available as 240, 480 and 960 gigabyte drives.
Integral was founded in London, England during 1989 and quickly became one of Europe’s leading DRAM specialists. Over the next two decades Integral expanded its product range as the solid-state flash memory market matured. Integral has long-term partnerships with leading component suppliers including Toshiba, Samsung and Hynix. International sales offices have been established in France, Spain, the Netherlands and the UAE..
Integral’s passion is to deliver the latest memory products built on quality, reliability and great prices.
