CASL Architecture:

HPE Nimble Storage solutions are built on its patented Cache Accelerated Sequential Layout (CASL) architecture. CASL leverages the unique properties of flash and disk to deliver high performance and capacity – all within a dramatically small footprint.CASL and InfoSight form the foundation of the Adaptive Flash platform, which allows for the dynamic and intelligent deployment of storage resources to meet the growing demands of business-critical applications.

Key Innovations from CASL

  • Flexible Flash Scaling
    Flexibly scale flash to satisfy the changing performance demands of today's business-critical applications.
  • Adaptive Flash Service Levels
    Tailor the amount of flash allocated to workloads on a per-volume basis. Assign one of three flash service levels (All Flash, Auto Flash and No Flash) to accommodate latency-sensitive critical applications to capacity-optimized applications, for management efficiency and optimal TCO.
  • Dynamic Flash-Based Read Caching
    CASL caches "hot" active data onto SSD in real time—without the need to set complex policies. This way it can instantly respond to read requests—as much as 10X faster than traditional bolt-on or tiered approach to flash.
  • Write-Optimized Data Layout:
    CASL collects or coalesces random writes, compresses them, and writes them sequentially to disks. This results in write operations that are as much as 100x faster than traditional disk-based storage.
  • Inline Compression
    CASL compresses data as it is written to the array with no performance impact. It takes advantage of efficient variable block compression and multicore processors. A recent measurement of our installed base shows average compression rates from 30 to 75 percent for a variety of workloads.
  • Scale-to-Fit Flexibility
    CASL allows for the non-disruptive and independent scaling of performance and capacity. This is accomplished by either upgrading the storage controller (compute) for higher throughput, moving to larger flash SSD (cache) to accommodate more active data, or by adding storage shelves to boost capacity. This flexible scaling eliminates the need for disruptive forklift upgrades.
  • Scale Out
    Scale capacity and performance beyond the physical limitations of a single array by seamlessly clustering any combination of HPE Nimble Storage hybrid arrays. Eliminate capacity silos and performance hotspots, and easily manage all hardware resources across the cluster as a single storage entity.
  • Snapshots and Integrated Data Protection
    CASL can take thousands of point-in-time instant snapshots of volumes by creating a copy of the volumes’ indices. Any updates to existing data or new data written to a volume are redirected to free space (optimized by CASL’s unique data layout). This means there is no performance impact due to snapshots and snapshots take little incremental space as only changes are maintained. This also simplifies restoring snapshots, as no data needs to be copied.
  • Efficient Replication
    HPE Nimble Storage efficiently replicates data to another array by transferring compressed, block-level changes only. These remote copies can be made active if the primary array becomes unavailable. This makes deploying disaster data recovery easy and affordable – especially over a WAN to a remote array where bandwidth is limited.
  • Zero-Copy Clones
    HPE Nimble Storage arrays can create snapshot-based read/writeable clones of existing volumes instantly. These clones benefit from fast read and write performance, making them ideal for demanding applications such as VDI or test/development.

Scalable Storage Capacity and Performance


With HPE Nimble Storage's Adaptive Flash platform, it is easy to accommodate application growth by scaling performance, capacity, or both—efficiently and non-disruptively. While the CASL architecture enables seamless, independent scaling, InfoSight's powerful deep-data analytics deliver precise guidance on the optimal scaling approach to fit the requiremets of critical applications.

With the Adaptive Flash platform, organizations can:

  • Flexibly scale flash to accomodate a wide variety of application working sets
  • Scale up performance by upgrading compute for greater throughput and IOPS
  • Scale capacity by adding additional HDDs or expansion shelves
  • Scale capacity and performance together by clustering any combination of HPE Nimble Storage arrays
Scale to fit

Scale Out


HPE Nimble Storage's Adaptive Flash platform features a scale-out architecture that makes it easy to scale capacity and performance beyond the physical limitations of a single array. Any combination of HPE Nimble Storage CS-Series arrays can be seamlessly configured into a storage cluster that accomodates growing business-critical workloads and supports new ones, without complicating storage management by creating additional silos or breaking the budget with forklift upgrades. HPE Nimble Storage's innovative approach to scale-out storage dramatically simplifies configuration, upgrades, and management.

With HPE Nimble Storage scale-out you get:

  • Single-console management of all storage hardware resources as a single entity
  • Dynamic load balancing to eliminate performance hot spots
  • Multi-array data striping, enabling any application to fully leverage the collective hardware resources of the scale-out group
  • Seamless reconfiguration and hardware refreshes, without downtime
  • Flexible configuration of any combination of HPE Nimble Storage arrays, maximizing storage ROI
