The document discusses the adoption of solid-state storage (SSS) in the market, highlighting its benefits and dispelling common myths about its reliability, cost, and accessibility. It emphasizes the rapid growth in capacities and price reductions, as well as the versatility of SSS for both large and small organizations. Additionally, it introduces Dell's fluid cache technology to enhance application performance by reducing latency.

2. Hype or the start of something big?
Where is the industry in the adoption of solid-state storage?
Analysts agree: We are right at the beginning of a major change in the market that will see massive adoption.

3. Solid-State-Storage
What is it:
•
Solid-state storage is the application of non-volatile memory (NVM) for long term data storage.
•
NAND flash is the most commonly used.
Trends:
•
Capacities are growing rapidly
•
Prices per GB dropping by 38% each year.

4. Myth #1: SSS is unreliable
True: NAND flash chips have a limited life-cycle
Error correction codes (ECC) to manage bit errors have been in use for over 40 years
Advanced techniques like wear-leveling, over-provisioning are combined with ECC to provide solid-state storage systems that easily last 5 years in production.

5. Myth #2: SSS is expensive
True: More costly than HDDs
Prices are dropping rapidly.
Solutions that utilize SSS well can displace solutions requiring a large amount of traditional spindles to provide performance, at a much lower CAPEX.

6. Myth #3: SSS requires special skills
Some traditional SAN solutions still require complex manual configuration to utilize SSS.
However modern highly virtualized SAN designs automatically incorporate SSS as a tier or cache.

7. Myth #4: SSS is only for the large data center
The advent of hybrid storage solutions, scale-out architectures and automated tiering has made the benefits of SSS accessible to small and medium-sized organizations.

8. Many architectures available
•
In the server PCIe attached
•
In the server as an SSD
•
In shared storage as a cache
•
In shared storage as a tier
•
In a hybrid storage system
•
In shared storage as a dedicated high speed array
