The Truth About Flash Storage

Posted on: March 2nd, 2016 by Daniella Lundsberg

Flash Storage Sizzles

You’re on a seemingly endless journey to optimize operations and squeeze every last bit of performance from your data center. You require as many 9’s of reliability as you can get. Flash storage promises application acceleration, amazing throughput, low latency and consistent performance. It all sounds great, but can you afford it?

Balancing Performance And Budget

While many factors go into calculating the total cost of ownership, you may be surprised to learn how affordable the cost of flash storage has become. Like other technologies that mature and become more widely consumed, the upfront cost of flash has gotten to the point where it is comparatively priced to spinning disks. At around $2 per GB, even if all else were equal, flash storage would be attractive.

All else is not equal. All-flash storage solutions win the high-performance battle (delivering hundreds of thousands of IOPS at under 1ms latency); they have more density so they take up less rack space with a significantly smaller footprint (less square footage needed in your data center); they run more efficiently (lower power consumption saves on energy and cooling costs); and are scalable and resilient.

Flash Arrays Are Not All Equal

When it comes to performance, flash arrays vary widely—not just in terms of performance, but in terms of consistency and predictability of performance. While you can add a flash tier to a traditional spinning disk system, you won’t realize the same highly consistent performance levels that you would with an all-flash array. All-flash arrays are exclusively made with flash memory and built on a flash-optimized architecture. This is the difference and what makes the delivery of consistent performance, resiliency, scalability, and data mobility possible.

HP 3PAR StoreServ 7450 All-Flash Storage

HP 3PAR StoreServ 7450 Storage provides the highest performance among the 3PAR 7000 StoreServ family and guarantees to double your virtual machine density. With hardware assisted thin storage it is the only platform that guarantees a 50% reduction in capacity requirements, thereby reducing the effective cost of flash media substantially. HP 3PAR StoreServ 7450 adheres to the four architectural requirements for flash-based arrays:

Performance acceleration – zero bottlenecks with faster I/O and flash-optimized caching

  • Efficiency optimization – extends the life and utilization of flash media
  • System resiliency – provides constant access with low latency and no IOP degradation
  • Data Mobility – allows for seamless movement of old data and applications

And, unlike other purpose-built flash arrays, the HP 3PAR StoreServ 7450 doesn’t require you to introduce an entirely new architecture into your environment to achieve flash-optimized performance.
