Flash Storage

Discover the Latest Revolution in Flash Storage

The explosion of big data has exponentially increased storage capacity requirements. While the proliferation of data storage needs are a conundrum, it’s only one side of the coin. Accessing that stored data is the other side of the problem that companies face.

Making strategic business decisions is oftentimes dependent on the ability to quickly retrieve stored information. Searching the endless sea of content requires good metadata, along with the ability to cache frequently accessed data.  Utilization of flash to store content is a growing trend companies are implementing to solve the data storage/data access dilemma.

Here are a couple of the latest revolutions in Flash Storage that are poised to solve the enterprise data storage issue:

Enterprise Multi-Level Cell (eMLC) Flash

Traditionally, Single-level Cell (SLC) Flash like IBM FlashSystem 710 (formerly called Texas Memory Systems RamSan-710) has been implemented for enterprise Solid State Drives (SSDs) over Multi-level Cell (MLC) Flash.  The reason is durability and the ability to provide four levels of data correction like systems such as the IBM FlashSystem 720 offer.  High costs of SLC have forced companies to look for cost-effective solutions such as MLC Flash equipped with bad block management (BBM) algorithms.  Coupled with sophisticated wear-leveling, MLC Flash arguably provides the necessary reliability to manage enterprise applications. Despite this, there is a belief that MLC is still unreliable for enterprise environments.

However, an alternative has emerged.  Enterprise MLC (eMLC) is a superior flash storage medium designed to support Tier 1 applications.  For instance, IBM FlashSystem 810 (formerly called Texas Memory Systems eMLC RamSan-810) delivers exceptional performance, reliability, and affordability all within the confines of 1U of rack space.

Innovative eMLC Flash like FlashSystem 810 provide a nonvolatile storage media that ensures data is not compromised during a power outage by utilizing battery-backed RAM.  The backup holds flash translation tables until power is restored; ensuring user productivity is maximized by eliminating user downtime while waiting for index reconstruction.

Three-level Cell (TLC) Flash

Three-level Cell (TLC) arrival, which stores three bits per cell, marks another revolution in flash storage technology. Flash capacities have significantly increased with TLC; however each additional bit per cell diminishes working life as a result of increased electronic complexity and decreases speed.

The rise of eMLC and TLC flash technologies signifies a new chapter in enterprise application management.  These exciting new technological storage capabilities are changing the way enterprise data storage and electronic content management are viewed within companies.  TLC and eMLC flash technologies also increase the flexibility for companies to deliver cloud storage solutions.
