Nimble Storage CS200 Series

Designed for Small to Midsize Organizations or Distributed Sites

Designed for mid-sized organizations or branch offices, the Nimble Storage CS200 series is a great fit for applications such as virtual desktop infrastructure (VDI), virtual server consolidation and Microsoft applications. These applications demand the non-disruptive scalability, high IOPS, and high capacity offered by the Nimble CS200 series, which is due to its unique CASL architecture. CASL stands for Cache Accelerated Sequential Layout, a patented architecture that is designed as a hybrid solution combining the exceptionally quick random read performance of flash and the cost-effective capacity offered by hard disk drives.

  1. The CS420 model is available in CS420-X2, CS420-X4, and CS420-X8 options only.
  2. Raw and effective capacities are calculated using Base 10 (i.e., 1 TB = 1,000,000,000,000 bytes) after excluding space for parity, spares, and system overhead; the range represents 0 to 2x compression.
  3. Maximum capacity is the capacity of the base array and maximum number of expansion shelves.
  4. Minimum usable capacity denotes the base capacity available to users once parity, spares and system overhead are deducted from overall raw capacity. Compression dramatically increases overall effective capacity.
