A Paradigm Spins Down

Which is better (and less cliché) than a paradigm that shifts, in my opinion. But based on public and private comments from readers, it's well past time to do away with these fault-prone spinning platters called storage arrays. Here's why.

Which is better (and less cliché) than a paradigm that shifts, in my opinion. But based on public and private comments from readers, it's well past time to do away with these fault-prone spinning platters called storage arrays. Here's why.This conversation -- that spinning drives are the data center's clunkiest dogs -- isn't a new one. But what it took to change the tenor of what's been repeated during the last five years was the voice a of a large and influential user. Specifically Google. About a year ago, the search engine giant released a study that severely undercut the performance guarantees of the major disk vendors.

Robin Harris covered this interesting issue in his Storage Mojo blog, and also included a thorough discussion of what's meant and implied in the terms mean time between failure (MTBF) and annual failure rates (AFR), two metrics that are the basis of vendor warranties.

Then, earlier this past March, some researchers from the University of Illinois did some piling on. Yes, disk failure contributes to 20% to 55% of storage subsystem failures; unfortunately, other physical interconnects like broken wires, shelf enclosure power outages, and HBA failures accounted for anywhere from 27% to 68% of problems. Ouch.

So as I look out on the horizon and see solid state, flash, even holographic storage, I wonder what it will take for the industry to wean itself off of spinning disk. Vendors have plenty invested in the systems and interfaces, not to mention a nasty dependence on the revenue stream they derive from these commodity products. Google and some academicians can't single-handedly shame makers of storage products away from disk. But they can shift the conversation so that there's discussion of amazing levels of reliability, rather than repair or replacement.

There's a paradigm that data center pros would be happy to adopt.

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2014-3580
Published: 2014-12-18
The mod_dav_svn Apache HTTPD server module in Apache Subversion 1.x before 1.7.19 and 1.8.x before 1.8.11 allows remote attackers to cause a denial of service (NULL pointer dereference and server crash) via a REPORT request for a resource that does not exist.

CVE-2014-6076
Published: 2014-12-18
IBM Security Access Manager for Mobile 8.x before 8.0.1 and Security Access Manager for Web 7.x before 7.0.0 FP10 and 8.x before 8.0.1 allow remote attackers to conduct clickjacking attacks via a crafted web site.

CVE-2014-6077
Published: 2014-12-18
Cross-site request forgery (CSRF) vulnerability in IBM Security Access Manager for Mobile 8.x before 8.0.1 and Security Access Manager for Web 7.x before 7.0.0 FP10 and 8.x before 8.0.1 allows remote attackers to hijack the authentication of arbitrary users for requests that insert XSS sequences.

CVE-2014-6078
Published: 2014-12-18
IBM Security Access Manager for Mobile 8.x before 8.0.1 and Security Access Manager for Web 7.x before 7.0.0 FP10 and 8.x before 8.0.1 do not have a lockout period after invalid login attempts, which makes it easier for remote attackers to obtain admin access via a brute-force attack.

CVE-2014-6080
Published: 2014-12-18
SQL injection vulnerability in IBM Security Access Manager for Mobile 8.x before 8.0.1 and Security Access Manager for Web 7.x before 7.0.0 FP10 and 8.x before 8.0.1 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.
