XMC for Metadata

• Latency. XMC delivers predictable, uniform, scalable I/O across reads, writes, read-write mixes, small-to-large block-size, sequential or random access, and any combination thereof. Write performance comes without penalty, nearly reaching read performance, whether random or sequential. XMC does not require managing system RAM, application tuning, device tuning, or dedicated file systems.

  An independent laboratory found that the XMC's worst recorded performance was better than an industry leading disk array's fastest recorded cache performance.

• Scalability. XMC uses block I/O with standard Fibre Channel interconnect. Individual XMC units provide 16-256GB capacity, scaling to any capacity via standard Storage Area Network (SAN) methods.

• Convenience. XMC connects directly to servers or to a SAN fabric. No configuration is necessary out of the box. The design emphasizes standard interfaces in all applicable areas, such as SNMP and syslog for event monitoring, HTTP for the GUI, and SSH for the command-line interface. Installing, monitoring, and managing an XMC is fast and easy.

What would you do differently if you could manage your metadata with orders of magnitude better performance and rational pricing?

• Sustainable Low Latency. Uniform microsecond response time under load. No other technology provides remotely comparable performance for metadata storage with similar response time, throughput and support for random or sequential I/O (reads, writes, mixtures, small and/or large blocks concurrently). Latency performance remains steady, even with high concurrency.
• Concurrency. Compared to any existing technology, XMC provides the best concurrent I/O access available - and without penalties. XMC will provide hundreds of concurrent initiators uniform and predictable performance.
• Performance. Compared to buffer cache, XMC provides equivalent performance but also provides persistence, recoverability, shareability, and scalability across systems, health monitoring, and native reporting. Compared to flash drives, the XMC provides orders of magnitude faster performance, more reliable data integrity, and system-level management resources, but without any write-penalty, application tuning, performance wobble, or temporal storage degradation. Compared to disk arrays, XMC provides orders of magnitude better latency, dramatic IOPS cost-advantages, and orders of magnitude superior "greenness".
• Green Savings. The energy alone needed to power a disk array delivering 200,000 IOPS (or 1/2 an entry-level XMC) costs 2X more in one year than an XMC unit costs. Apples-to-apples, the energy needed to power an XMC costs 5% (yes, 1/20th) the energy needed to power a comparably performing disk array.
• Scalability. XMC capacity reaches 256 GB in a box. Since XMC uses block I/O, adding more capacity is no different than adding another disk to a Storage Area Network (SAN). Need 2 TB of metadata? Add 8 XMCs.
• Maintainability. XMC units provide native internal health monitoring and reporting. Units "self-heal" on-the-fly for many problems.
• All I/O Patterns "Sing". XMC performs uniformly well across all I/O profiles: small blocks, large blocks, reads, writes, random reads, random writes, mixtures of reads and writes, small random writes, high load, high concurrency. The performance numbers will surprise even a seasoned storage architect, from latency to throughput. Contact Econnectix for specifics.
• Seek Time. On a sustained basis, XMC provides more than 125X better seek time than the world's fastest recorded performance spike on a spindle disk. An independent, third party analysis determined that the fastest recorded cache performance for a leading disk array was slower than the slowest sustained performance recorded for an XMC.
• Persistence Modes. XMC emphasizes DRAM storage, but intelligently uses other integrated media for persistence security. Users may select policy-based persistence guarantees on a per LUN basis.
• 1.8 Million RPM Performance. The XMC provides orders of magnitude superior performance compared to spindle disk, flash disk, or disk arrays.
• Management Interfaces. XMC provides a command line interface (CLI) and GUI. The CLI permits managing any number of XMCs en masse through scripting. The GUI provides easy management of all aspects of the device.
• Operating Systems. Linux, Windows, Solaris, and AIX supported.
• Automated Health Monitoring. The XMC self-heals for most problems that can occur, eliminating problems before they ever are noticed. Additionally, XMC constantly monitors storage health, and can report status via SNMP, Syslog, or HTTP down to the second. Please contact your reseller for details.
• Uninterruptible Power Supply (UPS). The XMC comes standard with a UPS to protect against downtime. If a power outage does occur, the XMC will stay up as long as possible, gracefully shutting-down only if or when necessary to protect the data. When you bring the XMC back online after an outage, your data will be right where it should be.
