Faster Ethernet Gets Weird

June 19, 2015 by Stephen 6 Comments

“One size fits all” doesn’t work for Ethernet, but this proliferation of speed options sounds like trouble without automatic capability negotiation. It’s nice to have options, but the IEEE must remain focused on interoperability and rein in the interests of the various companies proposing next-generation Ethernet technologies.

Interop NYC and The Great Debate: ISCSI Beats Fibre Channel

October 3, 2011 by Stephen 4 Comments

The battle lines are drawn between 8 Gb Fibre Channel and 1 Gb or 10 Gb iSCSI and NFS. This is the baseline for my Interop debate. I am not arguing about the future of SAN, or even iSCSI versus NFS. Rather, I am arguing that most businesses would be best served by implementing an iSCSI SAN rather than purchasing Fibre Channel today.

FCoE vs. iSCSI – Making the Choice

May 20, 2011 by Stephen 18 Comments

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.

Which Small Enterprise Storage Arrays Are Worth Considering?

April 8, 2011 by Stephen 1 Comment

It’s never been a better time to be in the market for enterprise storage products, with many excellent options available at affordable prices. But the market can be confusing for the uninitiated, with a variety of network options and capabilities. Even those of us “in the know” about enterprise storage are sometimes surprised by the offerings and companies in this space! So when Jerome Wendt from DCIG approached me to collect data for a market overview and buyer’s guide, I was excited. It was my big chance to really get to know these products!

Infographic: Real-World Port Throughput Relative To Thunderbolt (Formerly Light Peak)

February 21, 2011 by Stephen 2 Comments

Just how fast is 10 gigabits per second anyway? To help out, I’ve prepared another napkin-tastic infographic!

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

How Will Cisco Recover From The Consumer Strategy Blunder?

January 2, 2013

Cisco made a massive strategic blunder in the last decade, aggressively moving into consumer devices rather than focusing on their core enterprise and service provider markets. It seems that Cisco is now in the process of rectifying this mistake, but charting a path to growth is an entirely different matter!

Storage Changes in VMware vSphere 5

July 16, 2011

Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.

What’s the Difference Between a Jailbroken and an Unlocked Phone?

May 5, 2012

If you’ve traveled much, you’ve probably run across â€œunlockedâ€ mobile phones and devices. If you own an Android or iPhone smart phone, you probably also heard about â€œjailbreakingâ€. It seems like lots of people are confused about these two things, so I decided to write down a quick post explaining them.

It’s Time To Move Beyond Passwords (Especially On Web Sites)

January 8, 2016

Sure, single sign-on puts all your eggs in one basket. But this is vastly preferable to trusting that hundreds of third-party baskets are secure, especially when they prove on a weekly basis that they aren’t! It’s time to put distributed passwords behind us and switch to systems like SAML, both for businesses and consumers.

How To Keep Your Family Activities In Sync With A Shared Google Calendar

April 18, 2010

Smartphones, computers, and iPads are proliferating in families today. Although my three kids do not (yet) have their own mobile phones, we still have quite a few devices with calendar functions: An iPhone each for me, my wife, and our au pair along with an iPad and a few computers. Using Google Calendar, we have set up an awesome shared calendar to keep all of our activities in sync. Read on for instructions!

Scaling Storage At The Client

November 25, 2013

Scaling storage is a serious challenge for the industry, but there is a great deal of thought, effort, and creativity going into it right now. Companies like Gridstore, Oxygen Cloud, and Cleversafe have come up with effective client-side solutions to enable scale-out storage to sing. If you’ve got an appropriate application, client, or gateway, scale-out is a real possibility!

From LAN Manager and SMB to CIFS: The Evolution of Prehistoric PC Network Protocols

March 22, 2012

Computers aren’t much good on their own. This simple fact was evident even at the dawn of the microcomputing age, and has never been more true today in the “post-PC” world. If the standard microcomputer is the “Wintel” box (Microsoft’s Windows, Intel’s CPUs, and all that implies) then the standard network services protocol is SMB. So let’s take a nice deep dive into SMB, past, present, and future!

The Prime Directive of Storage: Do Not Lose Data

December 12, 2014

People call on storage devices and systems to do lots of things, from accelerating I/O to copying and sharing data. But at the heart of it all, storage arrays really have just one job: Do not lose data!
