Storage Changes in VMware ESX 3.5 Update 4

March 31, 2009 by Stephen Leave a Comment

Like clockwork, VMware has cranked out another update to their flagship enterprise product, ESX 3.5. The last update came out in early November, 2008, and included some major new functionality. What’s in store this time to intrigue storage folks? Not much. For more information on earlier updates, see my articles: Storage Fixes in VMware ESX […]

Storage Folks Are Talking 10-Gig and FCoE

November 21, 2008 by Stephen 2 Comments

I continue to be amazed by the level of interest I’m seeing in Fibre Channel over Ethernet (FCoE) and 10 Gb Converged Ethernet among storage people. As I noted after my Charlotte virtualization seminar, end users at the largest enterprises seem to think that FCoE is their future, not just one of several options. But […]

Storage Changes in VMware ESX 3.5 Update 3

November 7, 2008 by Stephen 3 Comments

Just over three months after releasing Update 2 for ESX 3.5, VMware has released Update 3. That last Update brought major storage changes like VSS support, hot VMFS extension, Storage VMotion across Fibre Channel and iSCSI, and support for 10 Gb Ethernet and 8 Gb FC support. For more information on Update 2, see my […]

Reality Check: The FCoE Forecast

October 19, 2008 by Stephen Leave a Comment

This is part of an ongoing series of longer articles I will be posting every Sunday as part of an experiment in offering more in-depth content. There has been a lot of discussion in the storage industry about Fibre Channel over Ethernet (FCoE), making it the toast of Storage Networking World, but this technology remains relatively unknown […]

Storage Fixes in VMware ESX Server 3.5 Update 2

July 28, 2008 by Stephen 5 Comments

VMware just released Update 2 for VMware ESX Server 3.5 (Virtual Infrastructure), and it includes some storage fixes of note: Support for Volume Shadow Copy Service (VSS) for filesystems Windows Server 2003 and Windows Server 2008 guests. This means VMware services like VCB and SRM can now signal Windows Server to quiesce filesystems before creating a […]

The 2018 iPad Pro is a Beast!

The third-generation iPad Pro is a great machine but also a bellwether of change at Apple. It will be very hard for the rest of the mobile and client computing industry to keep up with this kind of progress!

ZFS Is the Best Filesystem (For Now…)

ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. Here’s why.

Co-Processors, GPGPU, and Heterogeneous Computing

June 26, 2017

I’ve been thinking a lot lately about microprocessors, from the many-core CPUs that AMD and Intel introduced recently to the massively scalable GPGPU processing that’s taking machine learning by storm. After years of consolidation on commodity x86 CPUs, it seems that the computing paradigm is turning again to specialized offload processors. This trend towards heterogeneous computing will change the face of hardware, from mobile devices to the datacenter.

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!

Virtual Machine Mobility: Of What, and to Where and in What State?

January 16, 2012

Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.

Hands-On Review: Unicomp Spacesaver M Keyboard for Mac

July 3, 2012

I would not hesitate to recommend the Unicomp Spacesaver M to Macintosh users used to an original IBM Model M, and I am admittedly a tough customer. I wish that Unicomp would update their website, packaging, logo, and keyboard graphics, but none of this really matters as your fingers press the keys. If any keyboard is worth $100, it is the Unicomp Spacesaver M!

The Ideal pfSense Platform: Netgate RCC-VE 2440

September 21, 2015

After some frustration with stability and latency connecting my virtual pfSense router to my cable and DSL modems, I decided to switch to a physical box. I selected the Netgate RCC-VE 2440 as my hardware platform, since it’s the same box that pfSense themselves use as their OEM bundle. It also checks all the boxes with a dual-core Atom CPU, four Gigabit Ethernet ports, and low-power fanless design. Here’s my first impression and installation notes!

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!

Donate Your Swag to School Kids In Need

July 28, 2010

Trade shows are a veritable swag-fest, some with great loot and some with junk. I’ve been critical of the booth babe and chotchkie phenomenon, but my friend Kevin Houston has a better suggestion: Donate your (useful) swag like backpacks and pens to school kids in need.

Follow the Yellow Brick Road to the Software-Defined Future

November 29, 2012

The Software-Defined Datacenter is a great concept, but it just won’t work. The big enterprise companies will never allow VMware (and daddy EMC) to commoditize them out of existence, so useful implementations will be rarer than ruby slippers. The best we can hope for is point enhancements to enable greater virtual machine mobility through SDN and improved storage integration.
