A solid-state array (SSA) is a solid-state drive (SSD) housing nonvolatile all-flash memory that uses units called blocks, which are erasable and reprogrammable. SSAs lower latency and offer simple set-up and superior storage efficiency over legacy hard disk drive (HDD) storage. HDD storage experiences more failures because they have moving parts, whereas SSDs do not. SSAs easily integrate into data centers, use only a quarter the space and a tenth of the energy used by HDD storage.
All-flash arrays (AFAs) contain a multitude of flash drives that have zero moving parts. Compare this to HDDs, which are made up of moving arms and disks, and the first major difference becomes clear: moving parts make the reading, writing and retrieval process take much longer. When we compare the difference in the rate of data retrieval, an SSA takes seconds, while HDDs take minutes or even hours, depending on the level of the workload. What's more, the moving and spinning parts within HDDs wear down over time at a rate roughly 10 times that of SSDs, which have a failure rate of less than 0.3 percent. With just this evidence alone, it’s easy to understand why more and more businesses are transitioning to all-flash storage options for their data centers every day.
Not really. There are many rumors that suggest that “per gigabyte” flash storage is more expensive than HDD storage. But what those who suggest this don’t consider is the prohibitive cost of HDDs within the data center. After paying for four to five times the data center rack space, the utility bill for all the cooling, and a 24/7 on-call IT army needed for HDD storage, the cost of flash is certainly lower. In fact, the Tintri EC6000 Series, which takes up two units of rack space, can grow from 19 terabytes (TB) up to 40 petabytes (PB) and support more than 480,000 applications all from a single console. There is nothing in the HDD space that even approaches that level of storage capacity: the largest HDD drive for the data center today is 10TB, with a potential future of 40TB by 2020. When all the real-world variables are factored in, the truth of the matter is that SSA storage is no more expensive—and in many cases, cheaper—than HDD-type storage.
When it comes to putting Tintri All-Flash Array, performance is guaranteed. What’s more, you’ll have access to real-time and predictive analytics—so you can see what’s troubling your infrastructure right now, or determine what kind of needs you'll have in terms of scalability up to 18 months from today. As an SSA built for applications, Tintri’s AFA also offers automation to ensure you never have to manually configure or reconfigure for provisioning again. It also offers isolation for every application you run by placing each app in its own lane—the death of noisy neighbors alone is reason enough to switch from HDD to Tintri.
Want more? The Tintri All-Flash Array also offers autonomous operation with built-in best-practices for storage always on: you’ll get application deduplication, compression, redundant array of independent disks (RAID), and active-standby controllers with hot spares as part of Tintri automation. You’ll be able to run concurrent hypervisors of any make or model with support, including vSphere, Xen-Server, OpenStack, RHEV, or Hyper-V—all without partitioning.
Unique control with VM-level actions for infrastructure functions including snapshots, replication and QoS make protection and performance certain in production, and accelerate test and development cycles.
