Flash storage is one of the disruptive technologies that is changing the game in the European storage market.
Even though it is a relatively new technology and many vendors have only entered the European market in the past 12 to 18 months, customer adoption is already soaring, according to a forthcoming special study from International Data Corporation (IDC).
Performance-hungry workloads like virtual infrastructures and databases in particular are being deployed on flash systems and demand for flash systems continues to grow, the study shows.
Despite this being a relatively new storage market segment, the external flash storage market in EMEA is expected to reach a total value of $2,9-billion in 2014, showing year-on-year growth of 32%. The total capacity shipped with flash-powered arrays is expected to hit 3,53 exabytes in 2014.
Flash-powered arrays can be divided into two groups. Hybrid flash arrays (HFAs) are the main category in the market, given their ability to reach an almost comparable performance with an all-flash system, but with considerably lower $ per GB. All-flash array (AFA) systems, although posting impressive 302% year-on-year growth in user value in 2014, remain a single-point solution in the data centre, with broader adoption hindered by the still high $/GB price gap compared with spinning media.
Western Europe accounted for roughly 75% of total EMEA flash market value in 2014, with adoption spreading from the UK to Germany, France, the Nordics, and Benelux, traditionally first adopters of new technologies, with southern
European countries following closely.
Central and Eastern Europe, the Middle East, and Africa (CEMA) follows suit with Western Europe in terms of HFA penetration in EMEA with the highest adoption seen in Russia, South Africa, Israel, and the Gulf countries. AFA demand is still very nascent in the emerging markets, with significant growth potential mostly from the Middle East sub-region.
“European organisations have quickly adopted flash storage systems for their performance-sensitive workloads,” says Silvia Cosso, Western European storage analyst at IDC. “Now that all the major vendors have flash-powered arrays in their portfolio, and start-ups continue to push AFA into the market, competitive differentiation will come from data management capabilities and price. Future penetration of flash in the data centre is dependent on how quickly the dollar per Gb value will continue to decline.”
The flash storage systems market is a fast-growing segment of the EMEA storage systems market. IDC forecasts that total flash-optimised market value will grow at 15% CAGR from 2013 through 2018. The AFA market alone is expected to show an impressive 58% CAGR during the same forecast period, and will account for about 15% of EMEA’s total flash market by 2018.
Growth is mainly fuelled by a drop in flash dollar per gigabyte value, which is expected to fall by more than 70% from 2014 to 2018, as well as mainstream acceptance of flash systems for a broader range of workloads.
“HFA systems will still play a leading role in the EMEA market, with all tier one applications and some of the tier two switching to hybrid by 2018,” says Marina Kostova, CEMA storage analyst at IDC. “However, in the longer term, the general-purpose workloads are expected to move to AFA, thanks to likely future advancements in non-volatile flash memory and the falling cost of raw flash prices. Spinning media will not be entirely displaced from the data centre, however, and will mainly be confined to backup environments and cold data storage.”
