Pillar claiming their RAID5 is more reliable than RAID6? Wizardry or fiction?

Competing against Pillar at an account. One of the things they said: That their RAID5 is superior in reliability to RAID6. I wanted to put this on the public domain and, if true, invite Pillar engineers to comment here and explain how it works for all to see. If untrue, again I invite the Pillar engineers to comment and explain why it’s untrue.

Should techies or business owners decide on technology (or both)?

It’s no secret that, in most companies, the technology folks are primarily the ones deciding on which new technologies to adopt – after all, they are the ones that understand the technology, right? Business owners explain the business problem to the technologists, and the techies take it from there – and ultimately present 2-3 different solutions that will work and the business picks the cheapest (and/or the vendor that employs the rep that provides the most golf outings).

Is EMC under-sizing RecoverPoint and Avamar deals to win business?

It’s been a while since I wrote anything – unlike some, I actually have a day job and don’t use ghostwriters! Well, at least that’s my excuse.

My admiration for RecoverPoint is well known (see older post, which is referenced internally within EMC as a great pro-RecoverPoint article). It really is a good product and, next to VMware, my favorite EMC acquisition.

Should your backups to disk consume more disk than you use for production? Seriously?

So, let’s talk about this not-so-hypothetical customer… They have:

  • A few sites
  • A lot of data per site
  • Much of the data is DBs and Multimedia
  • No replication currently
  • Can’t back up everything currently
  • No proper DR
  • Fairly significant rate of change
  • Not the fastest pipes between sites

They asked me to propose a solution that will back everything up and cross-replicate the backups between the sites. They want to move as far away from tape as possible.

About the Data Domain acquisition – and is EMC really the best place for Data Domain?

Much has already been written about this imminent acquisition of Data Domain by either NetApp or EMC and, since opinions are like you-know-what, and I have one, here it is… if I ramble, forgive me. I have too much to say and I’m trying to be PC… I wrote and subsequently erased all kinds of stuff that could probably get me in trouble (the more you work with a company the more dirt you uncover, and I have several earth movers’ worth).
