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.

Worried about flash media wear-out? It’s never a problem with HP 3PAR StoreServ!

By Paul Haverfield, Principal Technologist, HP Storage APJ region   @PaulHavs

 

KeepCalm.jpgRemember the days – not so long ago – when any discussion around flash storage would inevitably include or lead to the dreaded topic of wear out? Eyebrows raised, frowns appear and general looks of worry and concern would quickly appear on the audiences’ faces. The worry factor – thoughts of “my business-critical data suddenly vanished because the storage media got tired and wore out" – would often be the major inhibitor to serious adoption of all-flash solutions. This problem was often exasperated when you learned that product warranty did not cover this so-called wear-out!

 

Thankfully, those days are now well and truly behind us – at least when flash is managed and deployed intelligently in an array platform designed from the beginning to adapt to new media types. It’s the architecture that matters.

 

New ShortTakes on StoreOnce and HP 3PAR AFA

P1040991.jpgI am back from what has been the longest vacation I've ever taken - almost 4 weeks.  While I did have three work events I attended in Europe, my ttime in Europe were pretty much all vacation.  I did post a blog from Germany about half way into the trip so check that out. 

 

I took over 1300 pictures.  And no, I wouldn't make you look at all of them (though many are amazing) but Google Plus has this very cool picture diary it created from the pictures I took with my SmartPhone.  I thought this was cool because all I had to do was add a few captions and remove a few pictures I thought weren't the best so if you want to see what I did, click on the link. But now, it's time for me to get to work.

 

Three new ShortTakes to share

If you remember, the week before I left for Europe was HP Discover.  That was also a rather intense week and I wasn't able to share with you a few ShortTakes from our product experts.  I have three to share - two focused on HP 3PAR StoreServ 7450 All Flash Array and the other on HP StoreOnce.  I'll include them here in "rapid fire" fashion with no other commentary as the ShortTakes speak for themselves.  As with other ShortTakes, I have the audio you can listen to and slides you can click through. So here they are.  (See the full blog post for the ShortTakes)

Time to get real about disaster tolerant all-flash array solutions

 

By Priyadarshi Prasad (Pd), Product Line Manager, HP 3PAR Storage

 

Now that the initial euphoria with all-flash solutions is starting to settle down, the conversations are getting more real. All-flash solutions are coming under the microscope. And it’s time to ask some very real questions of all-flash solutions: Granted you are fast, and you can be cheap if I believe your 6:1 (or is it 12:1 today) dedupe ratio. But can you protect my data and applications when a disaster occurs? How much data would I lose? How fast can I come back online? Let me address those questions with the framework of what I like to call the Three D’s of Disaster Recovery – data loss, downtime and distance.
