GreyBeards talk backup content, GDPR and cyber security with Jim McGann from Index Engines


Back in my consulting days, Index Engines was one of the most powerful tools in my toolbox.  Back then they were a lifesaver reading and indexing backup tapes so I could extract the files, or emails, that contained the keywords I was interested in. I found Index Engines, and our podcast guest Jim McGann, at Storage Networking World over a decade …

My Two Part Article on Fabrics for NVMe on SearchStorage


As regular readers of this blog, and/or listeners to the Greybeards on Storage Podcast, well know I think NVMe over Fabrics should eventually replace SCSI over various media as the Lingua Franca of storage. I’ve published a pair of articles on discussing the various fabrics upon which NVMe can be transported. The first, NVMe fabric options include Fibre Channel, RDMA covers the …

Twitter, Rumors and Data Integrity

I had a conversation Friday with a source I had considered generally reliable who said that an HCI vendor had been eliminated from a bake-off because They ACKed back to the application before getting the ACK from the 2nd node.  This resulted in data loss (paraphrased). I considered this concerning enough to tweet: I didn’t consider a single report reliable …

My Thoughts on the “Failure” of Optane on SearchStorage

Persistent memory, more specifically Storage Class Memory, promises to change some of the basic paradigms that have governed computing since the introduction of the database server. Intel’s 3DXpoint is supposed to be the next big thing but some people are calling Optane, Intel’s SSDs using 3DXpoint a failure. I tell the story, from my own slightly warped viewpoint on TechTarget’s

A Data Fabric Simplifies Data Management


While file services have been with us since the olden days of 10mbps Ethernet and NetWare file servers, most organizations still struggle with managing the multiple silos of unstructured data overflowing in their data centers. A data fabric, like MapR-XD, allows organizations to merge their data into a single name-space across not just scale-out nodes in their own data center …

Eliminating the Analytics Data Silo

Small Business Data Silos 845x321

For budgetary, and risk management, reasons many technologies, like VDI or the subject of today’s blog post big data analytics, enter most corporate data centers as stand-alone islands, complete with dedicated compute, storage and all too frequently rows of racks. The problem with islands, of course, is the cost of moving data back and forth between these islands and the …

Public Cloud Needs a Data Fabric


Public cloud services like Amazon Web Services (AWS) provide elastic environments for cloud native applications that use its Aurora or DynamoDB database services and EC2 compute instances. When it comes to storage, however, the storage service silos in the public cloud are if anything taller than in a corporate data center even if they’re hidden in the cloudy mists. A …

Hard Drive Evolution Part IV


When we last saw our hero the hard drive he had shrunk down to what we now call the large form factor with a 3.5” case with the higher performance 10,000 and 15,000 RPM drives using even smaller platters to keep their power consumption under control. Features that used to be limited to high-performance drives like voice coil positioners and …

Hard Drive Evolution Part 3


Stepper Motors to Voice Coils The first 5 ¼” hard drives like the ST-506, used a stepper motor to move the heads in and out. The head carriage was attached to a split steel band so each step of the motor in or out would define a track. Stepper motors were cheap, but even by the measure of those washing …
