Hello and welcome to the February 2017 issue of the Server StorageIO update newsletter.
With world backup (and recovery) day coming up on March 31, it makes sense to plan, review, assess, remediate, test and prepare in advance, to avoid or prevent a disaster later. Some of the themes in this months newsletter thus have a data protection angle which includes availability, resiliency, security, and backup/restore along with associated topics.
Keep in mind that there are many aspects to data protection, along with various tools, technologies, techniques along with tradecraft skills (experience). Speaking of tradecraft, the tips section has been expanded with more content to help refresh, or expand your fundamental data infrastructure skills and experiences. Watch for more about trade craft in future newsletters as well as elsewhere.
Speaking of data protection, if you had not heard or forgot, some recent events included the Australian Tax Office (ATO) whose resiliency solution appears to not have been configured for, well, availability, resiliency along with durability. You can read more about the ATO, lessons learned as well as fall out doing a Google search such as “australian tax office disaster“. Another recent disaster or disruption was Gitlab (not to be confused with Github) that lost around 300GB of data. Google something like “gitlab disaster” to see more.
In the case of Gitlab, it seems that a DevOp admin accidentally did something like a rm -rf (e.g. recursive and force) that if you know what that means, you know it might not be good.
As is the case with many disasters or near disasters and disruptions, they are usually the result of a chain of events, thus the mantra or isolate, contain faults to prevent snowballing into something worse. What’s concerning about Gitlab is that there are decades of lessons to be learned, known and preventable.
Hopefully Gitlabs experiences will prompt others in or moving to so-called platform 3 or new DevOps environment to use things in new ways, as well as prevent old problems using known tradecraft skills, lessons, experiences.
Also keep in mind that while technology can and will fail, hardware and software including clouds are defined by people, and when people are involved, human error is also present.
Some recent Industry Activities, Trends Announcements
Cloud and object storage vendor Cloudian announced a new appliance (e.g. tin-wrapped software) that they claim give high density low (cloud service like) pricing.
Check out iosafe who has a line of fire (and water) proof NAS and Windows Servers as part of availability data protection that can compliment clouds. For those of you who are also Synology fans (or users) take a look at what iosafe is doing for consumer, SOHO, ROBO, workgroup, SMB among other environments.
Speaking of data protection, how are you going about wiping or digital bleaching your storage including nand flash SSDs? Particularly are you doing deep cleaning including those hard to reach persistent non-volatile memory (NVM) cell locations in SSDs? Check out what Blancco is doing for deep cleaning to wipe or digital bleach your storage including SSDs.
Another aspect of data protection includes after your physical assets have been wiped clean (e.g. digital bleach), how will you safely dispose of the items? That’s where various vendors such as OceanTech among others come into play.
