Part 2: Some Server Storage I/O Workload Scripts and Results This is the second in a two part series of posts pertaining to using some common server storage I/O benchmark tools and workload scripts. View part I here which includes overview, background and information about the tools used and related topics. Following are some server I/O benchmark workload scripts to exercise various storage devices 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 The Workloads Some ways that can impact the workload performance results besides changing the I/O size, read write, random sequential mix is the number of threads, workers and jobs. Note that in the workload steps, the larger 1MB and sequential scenarios have fewer threads, workers vs. the smaller IOP or activity focused ... (more)

Which Enterprise HDD to Use for a Content Server Platform | @CloudExpo #Cloud #Storage

This post is the first in a multi-part series based on a white paper hands-on lab report I did compliments of Servers Direct and Seagate that you can read in PDF form here. The focus is looking at the Servers Direct (www.serversdirect.com) converged Content Solution platforms with Seagate Enterprise Hard Disk Drive (HDD's). I was given the opportunity to do some hands-on testing running different application workloads with a 2U content solution platform along with various Seagate Enterprise 2.5" HDD's handle different application workloads. This includes Seagate's Enterprise Pe... (more)

Server Storage I/O Benchmark Workload Scripts | @CloudExpo #Cloud #Storage #DataCenter

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 e... (more)

StorageIO Debuts at Top 400 Analyst List

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)
