Cloud Conversations: AWS S3 Cross Region Replication storage enhancements

March 25, 2015 – 10:01 pm
Cloud Conversations: AWS S3 Cross Region Replication storage enhancements Amazon Web Services (AWS) recently among other enhancements announced new Simple Storage Service (S3) cross-region replication of objects from a bucket (e.g. container) in one region to a bucket in another region. AWS also recently enhanced Elastic Block Storage (EBS) increasing maximum performance and size of Provisioned IOPS (SSD) and General Purpose (SSD) volumes. EBS enhancements included ability to store up to 16 TBytes of data in a single volume and do 20,000 input/output operations per second (IOPS). Read more about EBS and other recent AWS server, storage I/O and application enhancements here. The Problem, Issue, Challenge, Opportunity and Need The challenge is being able to move data (e.g. objects) stored in AWS buckets in one region to another in a safe, secure, timely, automated, cost-effective way. Even though AWS has a global name-space, buckets and their objects (e.g. files, data, ...

Data Protection Diaries: Are your restores ready for World Backup Day 2015?

March 20, 2015 – 12:43 pm
Data Protection Diaries: Are your restores ready for World Backup Day 2015? This is part of an ongoing data protection diaries series of post about, well, data protection and what I'm doing pertaining to World Backup Day 2015. In case you forgot or did not know, World Backup Day is March 31 2015 (@worldbackupday) so now is a good time to be ready. The only challenge that I have with the World Backup Day (view their site here) that has gone on for a few years know is that it is a good way to call out the importance of backing up or protecting data. However its time to also put more emphasis and focus on being able to make sure those backups or protection copies actually work. By this I mean doing more than making sure that your data can be read from tape, disk, SSD or cloud service actually going ...

Collecting Transaction Per Minute from SQL Server and HammerDB

March 19, 2015 – 11:24 pm
Collecting Transaction Per Minute from SQL Server and HammerDB When using benchmark or workload generation tools such as HammerDB I needed a way to capture and log performance activity metrics such as transactions per minute. For example using HammerDB to simulate an application making database requests performing various transactions as part of testing an overall system solution including server and storage I/O activity. This post takes a look at the problem or challenge I was looking to address, as well as creating a solution after spending time searching for one (still searching btw). The Problem, Issue, Challenge, Opportunity and Need The challenge is to collect application performance such as transactions per minute from a workload using a database. The workload or benchmark tool (in this case HammerDB) is the System Test Initiator (STI) that drives the activity (e.g. database requests) to a System Under Test (SUT). In this example the SUT is a ...

Cloud conversations: If focused on cost you might miss other cloud storage benefits

March 18, 2015 – 2:18 pm
Cloud conversations: If focused on cost you might miss other cloud storage benefits Drew Robb (@robbdrew) has a good piece (e.g. article) over at InfoStor titled Eight Ways to Avoid Cloud Storage Pricing Surprises that you can read here. Drew start's his piece out with this nice analogy or story: Let’s begin with a cautionary tale about pricing: a friend hired a moving company as they quoted a very attractive price for a complex move. They lured her in with a low-ball price then added more and more “extras” to the point where their price ended up higher than many of the other bids she passed up. And to make matters worse, they are already two weeks late with delivery of the furniture and are saying it might take another two weeks. Drew extends his example in his piece to compare how some cloud providers ...

February 2, 2015 – 3:06 pm
VMware announces vSphere V6 and associated virtualization technologies VMware has announced version 6 (V6) of its software defined data center (SDDC) server virtualization hypervisor called vSphere aka ESXi. In addition to a new version of its software defined server hypervisor along with companion software defined management and convergence tools. VMware vSphere Refresh As a refresh for those whose world does not revolve around VMware, vSphere and software defined data centers (believe it or not there are some who exist ;), ESXi is the hypervisor that virtualizes underlying physical machines (PM's) known as hosts. The path to software defined data center convergence Guest operating systems (or other hypervisors using nesting) run as virtual machines (VM's) on top of the vSphere hypervisor host (e.g. ESXi software). Various VMware management tools (or third-party) are used for managing the virtualized data center from initial configuration, ...

Server and Storage I/O Benchmarking 101 for Smarties

February 1, 2015 – 12:12 pm
Server Storage I/O Benchmarking 101 for Smarties or dummies ;) This is the first of a series of posts and links to resources on server storage I/O performance and benchmarking (view more and follow-up posts here). The best I/O is the I/O that you do not have to do, the second best is the one with the least impact as well as low overhead. Drew Robb (@robbdrew) has a Data Storage Benchmarking Guide article over at Enterprise Storage Forum that provides a good framework and summary quick guide to server storage I/O benchmarking. Via Drew: Data storage benchmarking can be quite esoteric in that vast complexity awaits anyone attempting to get to the heart of a particular benchmark. Case in point: The Storage Networking Industry Association (SNIA) has developed the Emerald benchmark to measure power consumption. This invaluable benchmark has ...

Server and Storage I/O Benchmark Tools: Microsoft Diskspd (Part I)

February 1, 2015 – 12:12 pm
Server and Storage I/O Benchmark Tools: Microsoft Diskspd (Part I) This is part-one of a two-part post pertaining Microsoft Diskspd.that is also part of a broader series focused on server storage I/O benchmarking, performance, capacity planning, tools and related technologies. You can view part-two of this post here, along with companion links here. Background Many people use Iometer for creating synthetic (artificial) workloads to support benchmarking for testing, validation and other activities. While Iometer with its GUI is relatively easy to use and available across many operating system (OS) environments, the tool also has its limits. One of the bigger limits for Iometer is that it has become dated with little to no new development for a long time, while other tools including some new ones continue to evolve in functionality, along with extensibility. Some of these tools have optional GUI for easy of use or configuration, while others simple have ...
