Full Story:

EMC Corporation (NYSE:EMC) announced general availability of EMC® XtremIO, the industry’s first and only all-flash array to provide consistent and predictable extreme performance to any application workload over any period of time, regardless of whether the array is idle or busy, empty or full. To achieve this, EMC XtremIO features several unique flash innovations: a scale-out multi-controller architecture with linear scalability; deduplication that is always on, and always inline; data protection that is 6X more efficient and 4X faster than traditional RAID.

            Under the covers, EMC XtremIO is architected differently than any other all-flash array. Four key technologies work in concert to maximize performance without compromising efficiency or durability:

  • Content-Based Data Placement
  • Dual-Stage Metadata Engine
  • XtremIO Data Protection (XDP)
  • Shared In-Memory Metadata

EMC expects XtremIO to be a leader in the all-flash array market, which IDC forecasts to grow to $1.2 billion in revenue by 2015*. The new array is already in high demand, with 10 Petabytes of effective deduplicated capacity already sold through EMC’s Directed Availability program (announced in March 2013).

XtremIO Technology Highlights

Customers are looking to all-flash arrays to support workloads that need predictable and consistent low-latency across datasets that frequently change – such as VDI, virtual servers, massively consolidated databases and test/development environments. With XtremIO, these workloads not only achieve better performance, but also improved $/IOPS and greater administrative simplicity. There are four key architectural differences that set XtremIO apart from other all-flash arrays:

  • Content-Based Data Placement keeps the array inherently balanced and optimized to within a fraction of a percent across all SSDs and array controllers and removes duplicate data inline in the data path.
  • Dual-Stage Metadata Engine allows the array to fully leverage the random access nature of flash and place data anywhere in the array without requiring system level back-end cleaning processes (also known as garbage collection). This enables XtremIO to avoid the up to a 50% performance hit in IOPS, up to 1000% increase in latency, and up to 10X reduction in flash endurance compared to other flash arrays that use system level garbage collection.
  • XtremIO Data Protection (XDP) is a flash-specific algorithm that guards against SSD failures while delivering up to 6X more usable capacity than traditional RAID. XDP allows end-users to utilize 100% of the capacity on XtremIO – while maintaining maximum levels of performance. Other all-flash arrays will begin to show degraded performance when they reach 60% to 80% of capacity. This means that XDP delivers up to 40% more usable capacity compared to other all-flash arrays. In addition, the efficient XDP algorithms deliver up to 4X better performance and flash endurance than RAID in long-term production data center conditions.
  • Shared In-Memory Metadata enables the array to deliver the widest range of performance, and to rapidly clone information already in the array to massively accelerate common tasks like deploying virtual machines. Virtual machine clones are created at up to 20X the network bandwidth between the host and the array, several times faster and with lower impact to production virtual machines than other all-flash arrays.

XtremIO is a scale-out array based on building blocks called X-Bricks. Each X-Brick is available with 10TB of capacity – with an additional option for 20TB of capacity expected to be available early next year. XtremIO arrays deliver up to one million fully random IOPS with over 250TB of effective capacity in a single XtremIO cluster with inline deduplication. A single XtremIO cluster scales from two to eight controllers and up to 128 cores, capable of handling any OLTP Database, virtual server and VDI workload – with all data services active.

In addition, XtremIO is integrated within the EMC ecosystem to provide additional capabilities, ease-of-use, and compatibility. A VCE Vblock Specialized System for Extreme Applications based on XtremIO all-flash arrays provides unparalleled VDI end-user computing performance at unprecedented cost per virtual desktop, which customers can begin ordering by the end of 2013. XtremIO array management is also integrated with VMware vSphere and accelerated with VMware’s VAAI storage APIs. In addition, XtremIO is supported with other EMC technologies including EMC VPLEX, EMC PowerPath® and EMC Secure Remote Support (ESRS).

Customer Quotes

Brian Dougherty, Chief Technical Architect at CMA Consulting Services

“CMA is a leader in building very large scale technical platforms for healthcare applications. Our multi-tenant Oracle RAC environment generates a mixture of large sequential and random IO workloads simultaneously. We needed a specialized weapon that could handle the large mixed random and sequential workloads, while never degrading performance. We also needed a solution that was simple to manage and configure – configuring 10’s of terabytes of storage in a matter of minutes versus hours – with protection. We chose XtremIO because it delivers better performance, is simple to manage and configure and significantly lowers our total cost of ownership. It stood far apart from other solutions and reset our expectations for what we can do as an IT organization in our Oracle RAC environment.”

Russ Norman, Senior Manager of Systems Engineering at E*TRADE

“Performance, reliability, and speed are critical in our application environments. We require an infrastructure that provides very low latency, allowing orders to be processed quickly. We are deploying XtremIO to get us to the next level of performance – but even more than that provide us with new levels of usability for our applications. With these lower storage latencies, we can process higher numbers of IOPS and move larger amounts of data. We found on average writing to the XtremIO array to be between 0.25 to 0.3 millisecond response time, with reads being somewhere around 0.2 millisecond. This was, consistent with workloads between 100,000 to 200,000IOPS. In addition, XtremIO’s thin provisioning and inline deduplication were selling points for us also for cost and capacity efficiency.”

Analyst Quote

Laura Dubois, Research VP of Storage at IDC

“What I find most compelling about XtremIO is the unique architecture. Core functions such as granular metadata processing, shared in-memory metadata handling and content-based data placement are enablers to XtremIO’s impressive sustained IOPS metrics while offering core services – including deduplication and copy data services. There are other all-flash arrays with impressive performance metrics – but not for a sustained basis. The other standout capabilities with this system are native inline deduplication, in-memory metadata only copy and a scale-out architecture. These are attributes not all of the ‘all-flash array’ solutions on the market offer.”

EMC Executive Quote

CJ Desai, President, Emerging Technology Products Division

“Flash continues to be a major disruptive force – and an incredible market opportunity in storage. There is an insatiable appetite for performance driven by next generation data center workloads in both physical and virtual environments. EMC’s strategy is to leverage flash technology across the entire storage infrastructure with a best-of-breed product portfolio that allows us to deliver customers choice. With XtremIO, we’re delivering this fast growing market with a specialized solution that delivers ‘more’ – more consistent and predictable performance, more scale, more integration and more data services. And most importantly, we’re doing this on a fundamentally better architecture, which will allow us to easily deliver even more value-added features over time.”
