Blogroll Update

July 28th, 2009 No comments

Over the past year, I have included some great reading links on my Blogroll.

Primarily the blogroll was divided into OEM and Non-OEM blogs. I do not think that classification stands true anymore.

Going forward, I will be implementing a new strategy. Will have 3 different blogrolls: Storage Blogs, Virtualization Blogs and Analyst Blogs.

The StorageNerve Blogroll will primarily only consist of blogs that are focused on technology, only in very exceptional cases, will I have a link on the blogroll that is for a non-technical blog.

I am not singling out any marketing blogs or any non-technology focused blogs, but really want to try to focus StorageNerve over the next year to primarily be a technology-focused blog.

A new Blogroll will be located on the left of the page, please check the Blogroll on 31st of July, 2009 for updates.

Cheers, @storagenerve

Storage Optimization

July 24th, 2009 No comments

Well the first question: What is Storage Optimization?

A lot of new storage technologies are up and coming that have either Storage Virtualization or Thin Provisioning built as its core value. Those technologies can help run your storage in a much efficient manner, but what are your options related to your existing infrastructure that may consist of EMC Symmetrix DMX & above, EMC Clariion CX & above, NetApp FAS series, NetApp G Series, NetApp V Series, HDS USP, HDS USPV, HDS AMS, IBM DS Series, HP Eva’s, LSI’s, SUN branded LSI’s, etc. I am not suggesting if you are running Storage Virtualization or Thin Provisioning you are running at 90 or 100 percent efficiency, there are still places where these technologies start building inefficiencies as your storage environment starts to mature.

The point I am trying to make is, what have you done last to optimize your Storage Environment. Over the past year, I have met a lot of customers including IT IT Planning folks, CIO organizations, IT Directors, Storage Managers, Storage Engineers where all these folks work so hard to maintain and manage IT Assets on the floor including Storage environments. A Storage Engineer is always busy trying to keep up with new projects, migrations, consolidations, etc. In the race of life to get promotion at work, make managers happy, keeping up with new technology & projects, we all forget about things we decided to do yesterday or rather the day you joined the organization.

When was the last time you thought about reducing your organizations OpEx and CapEx. When was the last time, you took your organization through a Storage Optimization exercise. Have you setup a Storage Economics practice within your Storage environments that would help you reclaim stranded storage, help you re-tier your storage based on business needs, help you increase utilization and reduce inefficiencies within your Storage Environments.

Responses we get talking to various Storage folks, we try to do the best we can to keep up with the day to day storage needs, and we went through an exercise to optimize our environment about 12 months ago.

Wait a minute, 12 months ago? Each wasted month is a savings lost.

In my previous blog posts, I have addressed some very fundamental issues related to Storage Environments that can help you achieve the necessary goals you might have for your organization.

Please see the related blog post below that show you how inefficiencies get built, how to your storage should be optimized and the overall savings you would realize as an organization:

Case Study:
We went through a POC for a customer with their existing storage environment (efficiency, utilization, tiering), Customer had some environments running 20% and 30% utilized with 1 single tier. They were looking to invest more into a specific storage platform. Apparently the folks were just astonished to review the results and the savings.

Total savings of 10 Million US dollars over 3 years with establishing a Storage Economics practice for their 1 PB Storage Environment.

The above savings were minuscule, if there is a customer with a larger environment, the savings would increase substantially.
This savings can possibly help you acquire new technology or can be given back to the organization, making you a hero, may be take you much closer to your dreams.
