Some Server Storage I/O Benchmark Workload Scripts | Part 1
This is part one of a two-part series of posts about using some common server
storage I/O benchmark tools and workload scripts. View part II here which
includes the workload scripts and where to view sample results.
There are various tools and workloads for server I/O benchmark testing,
validation and exercising different storage devices (or systems and
appliances) such as Non-Volatile Memory (NVM) flash Solid State Devices
(SSDs) or Hard Disk Drives (HDD) among others.
Various NVM flash SSD including NVMe devices
For example, lets say you have an SSD such as an Intel 750 (here, here, and
here) or some other vendors NVMe PCIe Add in Card (AiC) installed into a
Microsoft Windows server and would like to see how it compares with expected
results. The following scripts allow you to validate your system with tho... (more)
Cloud Expo on Ulitzer
Following on the heals of being named one of three EcoTech warriors earlier
in the year, and then number 5 in the top ten independent bloggers at
StorageMonkeys earlier this year (plus appearing on InfoSmack), the momentum
continues more recently being named as the 23rd out of the top 30 influential
virtualization bloggers by Cloud Computing Expo (www.cloudcomputingexpo.com)
and Ulitzer (www.ulitzer.com).
If that were not enough, I was also surprised to learn recently that I have
also made a debut appearance at number 79 in the Technobabble top 400 analyst ... (more)
Happy Earth Day 2016: Eliminating Digital and Data eWaste
With Earth Day 2016 on April 22, here are some thoughts about electronic
For those involved in data management or data infrastructures, the following
are six tips to help cut the overhead and resulting impact of digital e-waste
and later physical e-waste. Most conversations involving e-waste focus on the
physical aspects from disposing of electronics along with later impacts.
While physical e-waste is an important topic, let's expand the conversation
including other variations of e-waste including digital... (more)
With the largest installment yet of a VMworld in terms of attendance, there
were also many announcements today (e.g. Monday) and many more slated for out
the week. Here are a synopsis of some of those announcements.
Software Defined Data Center (SDDC) and Software Defined Networks (SDN)
VMware made a series of announcements today that set the stage for many
others. Not surprisingly, these involved SDDC, SDN, SDS, vSphere 5.5 and
other management tool enhancements, or the other SDM (Software Defined
Here is a synopsis of what was announced by VMware.

How much SSD do you need vs. want?
By Greg Schulz
I have been getting asked by IT customers, VAR's and even vendors how much
solid state device (SSD) storage is needed or should be installed to address
IO performance needs to which my standard answer is it depends.
I also am also being asked if there is rule of thumb (RUT) of how much SSD
you should have either in terms of the number of devices or a percentage;
IMHO, the answer is it depends. Sure, there are different RUTs floating
around based on different environments, applications, workloads however are
they applicable to you... (more)
