Last week as part of our HP 3PAR OS 3.2.1 announcement, my 3PAR Thursday blog focused on the performance acceleration delivered by HP 3PAR OS 3.2.1. The announcement also talked about the HP 3PAR Flash Advisor toolset that helps HP 3PAR StoreServ Storage customers asses current capacity and performance profiles via built-in the 3PAR OS toolset in order to optimize current and future flash investments. This week, I’m talking about this in a bit more detail and explaining why these capabilities are so important to enable a smooth transition of application and workloads to use flash-based media.

 

New flash features with latest HP 3PAR OS 3.2.1

We released HP 3PAR OS 3.2.1 a few weeks ago but haven't publicly announced what that OS release brings to HP

3PAR StoreServ. Since the enhancements are substantial, I'll talk today at a high-level and over the next few days I'll have some of those other subject matter experts posting articles to go deeper on some of the news.  At a high level, we announced:

  • Adaptive Flash Cache for performance acceleration with read cache extension
  • Express Writes is another enhancement that improves latency without additional hardware
  • Flash Advisor tool kit helps smooth the transition to flash
  • 3PAR Thin Deduplication is now supported across the HP 3PAR StoreServ portfolio of 7000 and 10000 systems

Along with the ChalkTalk, there's also a demo video of Adaptive Flash Cache so head over to the full blog post to check that out.

Built for flash

A common theme emerges from flash startups when discussing other, more established storage platforms:

 

               “Storage Vendor ‘ABC’ is a legacy storage array retro-fitted with flash but not built for it.”

 

Flash_Optimized_Logo_308x220_tcm245_1608576_tcm245_1618609_tcm245-1608576.jpgI agree. But that's because there's no such thing. There's no such thing as "built for flash" or "legacy storage retrofitted for flash." Be it startup or legacy vendor, it makes no difference. The only thing that matters is how the storage solution optimizes and protects I/O. Let me explain.

Continuing our look at tape-as-NAS options

Graphic2.jpgPart 2: A closer look at tape-as-NAS – when to use disk or SSDs

In Part 2 of our series on when to use disk and when to use SSD, I’m focusing on using SSD in front of our StoreEver tape library as part of the tape-as-NAS (tNAS) solution. In Part 1, we explored how disk was the appropriate solution if you want quicker access to data that may be active for a period of time – more like a cache. Solid-state drives (SSDs) offer better read and write operation performance, lower latency, and lower power when compared to a standard spinning disk but at a greater cost. In this blog, I'll discuss how SSDs may be a better choice if your archive work flows need a “buffer” instead of a “cache.”  I'll also review what you should consider when choosing the appropriate SSD for your tNAS solution. At the end of the day, No matter what your use case demands, HP has everything you need for data archiving including HP Servers, disk storage, SSDs and HP StoreEver Tape libraries.

SSDs or disk? Buffer or cache? A closer look at tape-as-NAS options

Part 1: A closer look at tape-as-NAS - disks

A few weeks ago I wrote about a new emerging architecture for long term data retention that combines FLash drives and tAPE called FLAPE. Flash drives, or solid-state drives (SSDs), offer better read-and-write operation performance, lower latency and lower power when compare to a standard spinning disk.

 

In traditional transactional environments, these factors make a big difference. However you may wonder how this impacts an archive work flow? In this two-part blog series, I’ll show when you may want to use a disk or an SSD depending on your archiving workflow. Part 1 focuses on disk and Part 2 focuses on SSDs.
