In many new applications, data will live its entire lifespan in the Cloud. Created, managed, analyzed, acted upon and archived there. In fact, it has been reported that some analysts predict worldwide public-cloud spending in 2020 could be essentially double of that in 2016.

Whether cloud computing or cloud services, economics is a strong lure for some. For these companies, the Cloud is simply more cost effective and efficient for running applications and storing data.

So how do cloud providers keep up with the growing demand economically? How do cloud storage services offer high availability and consistent I/O performance delivered 24/7, 365 days a year?

Finding ways to maximize and streamline storage by running concurrent workloads across the storage infrastructure has become essential. Utilizing a tiered storage approach to optimize performance and cost is also key.

 

Meet the SkyhawkTM NVMe-compliant PCIe SSDs

 I’m very excited to introduce the first NVMe-compliant PCIe SSDs from our SanDisk brand. Skyhawk[1]  PCIe SSDs are optimized to give customers the ideal balance of fast and consistent performance, cost-effect storage and Quality of Service (QoS) to address large, unstructured data center workloads for cloud environments.

They are a great addition to Western Digital’s broad portfolio of storage solutions for the Cloud. Now cloud providers can slide across a consolidated cost/performance continuum.

 

So, why Skyhawk?

For cloud workloads that need higher throughput and faster response time, historically SATA SSDs provide high performance and low power requirements.  The SATA interface is also ubiquitous on the servers used in cloud data centers.

The challenge?  The current version, SATA III, is almost nine years old and capped at 6 gigabits per second, without plans to improve performance or reduce latency. A more detailed comparison of SATA interface here: Top Considerations for Enterprise SSDS – A Primer.

NVMe protocol circumvents SATA bottlenecks for improved performance and reduced latency (response time). Designed for Flash and future storage class memory solutions, NVMe’s direct connection to the CPU via PCIe streamlines the storage device stack and is significantly faster than the traditional SATA interface (see Table 1 below).

All major server manufactures have added support for NVMe-based U.2 SSDs in their products.  In a few years, we would expect to see deployed servers support the same number of NVMe U.2 drives as the SATA ones today.

The new Skyhawk NVMe-compatible PCIe SSDs  offers up to 3.84TB in capacity and comes in a highly serviceable U.2, 2.5-inch SFF with a PCIe interface.

The Skyhawk SSD also integrates Western Digital’s 15nm NAND Flash with a new high-performance PCIe Gen 3 SSD controller. Its Guardian Technology™ platform guarantees Enterprise Class reliability, endurance and performance.

Skyhawk delivers high performance, consistency and associated Quality of Service (QoS) to meet the rigors of un-structured data workloads in the Cloud.

 

Key Benefits

  • Nearly 3X the sequential performance compared to comparable enterprise SATA SSDs[2]
  • Lower 12W power envelope enables broader deployment compared to 25W PCIe SSDs
  • Compliant with industry standard NVMe 1.2 protocol with in-box drivers for all major OSes
  • Available in two write endurance swim lanes (Standard and Ultra)
  • Increased performance provides improved server consolidation

 

Specifications

  • High capacities, ranging from 1.6TB to 3.84TB
  • 2.5-inch hot-swappable U.2 SFF form factor

 

Typical Use Cases include Cloud, Object Storage, Microsoft® Storage Spaces Direct (S2D), Microsoft® Azure Stack (MAS), OLAP, File/Web Servers, Media streaming or VoD.

 

The Skyhawk NVMe compatible PCIe SSD is currently sampling to select OEMs, with general availability Q2 of this calendar year.
