Why All-Flash?

All-star Performance. Green Efficiency. Superior Reliability.

Over the past decade, while the rest of IT infrastructure has improved exponentially in performance, storage has been virtually stagnant, increasing in capacity but not in performance. The table below shows how CPU, DRAM, network, and bus performance have outpaced storage by 16 to 400 times. To have kept pace, hard drives would need to spin at 6 million rpm today. Instead, storage is now the prime bottleneck in datacenters.

Excessive Operating Costs of Disks

At the same time, power, cooling, rackspace, and datacenter maintenance costs have reached record levels. According to Gartner, storage consumes 37% of overall datacenter power. Organizations face relentless data growth without the facilities or operating budget to support them. Despite achievements in areal density, disk storage remains based on power-hungry, hot, large and comparatively unreliable technology.

Hybrids and Tiers Are Inadequate Band-Aids

Caching and primary storage tiering have emerged as possible solutions to these challenges, but these approaches have significant drawbacks.

  Strengths Weaknesses
  • Accelerates reads and sometimes writes
  • Helps only if data happens to be in cache
  • Small cache (usually less than 10% of storage capacity) means cache hits are rare
  • Inconsistent performance (cache misses are 100x slowers than cache hits)
  • No reduction in power consumption
  • No cooling or rackspace savings
  • No improvement in reliability or rebuild times under hard drive failure conditions
  • Moves data between SSD, 15K and 10K rpm disk
  • Complex IO right-sizing required to determine the (supposedly) ideal blend of SSD, fast HDD, and slow HDD
  • Data is constantly in motion, increasing power consumption and hardware wear
  • Data location may not be clear when there is a failure during tiering action
  • Recipe for vendor lock-in, since all storage tiers must be procured from the same vendor
  • Non-automated solutions require manual effort, complicating administration
  • Insignificant gains in power or rack efficiency

Enter Nimbus Data All-Flash Systems

Nimbus Data believes that all-flash is the destiny of primary storage and that all customers deserve access to this incredibly powerful technology. With the Gemini all-flash array, organizations can skip the Band-Aid and go straight to the ideal solution — a storage platform based entirely in flash — affordability and without feature compromises.

  • Delivers consistent and predictable high performance by eliminating rotational latency, dramatically accelerating both random and sequential workloads.
  • Consumes one-fifth the power of disk arrays of the same capacity, cutting operating costs while enabling greener, denser, and longer-life datacenters.
  • Eliminates sensitive moving parts, minimizing the risk of mechanical or environmentally-induced failures to improve application availability.
  • Provides complete storage software for unified SAN, NAS, and DAS, end-to-end data protection, and efficient capacity management in one elegant solution.
