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.

How server and storage evolution is driving the need for Gen 5 Fibre Channel

By Rohan Viegas, Worldwide Product Management, HP Storage

 

Gen 5 Fibre Channel is more than just 16Gbps speeds. It unleashes the full potential of high-density server virtualization, cloud architectures and next-generation storage. It offers a purpose-built, data center-proven network infrastructure for storage. And it delivers unmatched performance, reliability and simplicity. Today, Rohan Viegas talks about how the server and storage evolution is driving the need for Gen 5 Fibre Channel and how the HP StoreFabric SN6500B 16Gb Fibre Channel Switch helps meet that need.

More on the Flash Module for the P9500

P9500.jpgLast week, I had a blog post and video I did of the Flash Module for the P9500 - something I learned about while at HP Discover.  Things were just a wee bit busy for me and I didn't have time to learn much about the Flash Module while at Discover, but I called Ayman Abouelwafa.  Ayman is a senior architect in our enterprise storage lab and my go-to engineering guy when I need to understand something about P9500.  Ayman was in one of my first video blogs and was very helpful in doing a video we did talking about our collaboration with Hitachi Japan.

 

After talking to him, I realized there was a lot I didn't get from my 4 minute conversation at HP Discover - so here's a bit more of what I learned from Ayman.  First he told me about some new firmware.

 

Performance Accelerator

 

  • Ayman and his team worked with Hitachi Japan on Performance Accelerator, a new firmware-based program that significantly enhances the back-end random performance, targeting SSD and flash media.
  • This significantly expands the P9500 frame-limit for random IOPs.  Ayman told me the firmware enables around a million IOPs per P9500.  Wow!

Solid State Storage - why it's already changed IT and what's coming

Vish Mulchand_SNW SSD session.pngSNW Fall is happening in Santa Clara, yet another event I can't attend as my wife and daughter are enjoying a fabulous trip through Europe. One of the hot topics that will be certainly getting a lot of attention is solid state storage.  My colleague Vish Mulchand, Director of Product Management, joined me late Friday night to record this podcast with me as he presents a session at SNW about solid state technology. 

 

It's a great discussion with Vish - here's an outline of what we covered:

  • Why has solid state changed the IT landscape?
  • Where are the different places customers can deploy solid state storage technology?
  • We discussed when to use solid state technology?
  • Lastly we talked about HP's offerings that include solid state - this is a short discussion.
