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

By Mark Fleischhauer, HP StoreEver Tape Storage Solutions Engineering Manager




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 will focus 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. 

HP 3PAR gets a boost with SSD

3PAR small.jpegToday we made a couple of announcements focused on solid state technology.  There are two pieces of the announcement - one focused on HP 3PAR and the other on HP ProLiant Gen8.  We announced an all-solid state drive (SSD) configuration for 3PAR.  We also announced HP Smart Cache for the HP ProLiant Gen8 servers.  It's server-based caching to accelerate performance.  Check out the blog post to get the details.  There's also a podcast you can listen to.
