CompTIA Storage + Passed!

Took the CompTIA Storage + exam on Saturday and passed, it was a pretty straightforward exam, I enjoyed it quite a bit. The study prep for it was also nice to learn, learned a number of things that will follow me through in my datacenter and system administration roles. Will use the knowledge from it to make effective datacenter decision moving forward, and I will have ap lan on my shelf for the book for reference.

Study Material Used:

Pluralsight: Nigel Poulon.
CBT Nuggets: Jeremy
Storage Networking book by Nigel Poulon.

Onward to the Cisco CCNA:R&S (ICDN2) pursuit to finish up that certification. I will either do VCP6-DCV after that or do Project + or possible both if I’m crazy enough. 🙂

MS Bug Affects Windows Server 2008 R2 writes to a Back End-SAN

Reading an article online today about a fix to an issue involving Windows Server 2008 R2 and it’s write performance to a Back-End SAN it made me curious. Since in a VMware world, especially, your always looking for way to improve back-end performance for SQL and other write intensive servers/applications and bleed as much perofrmance as possible.

After applying this hotfix perofrmance improved for Writes as-well as on reads.

Hopefully this hotfix helps other as it has helped me. 🙂

Veeam Backup & Replication v8

So the last few days I’ve been using Veeam’s Backup program for backing up VM’s at work to give the tool a try and I really like it.

Last week I got the VMware vExpert Award and I found out I can have Veeam Backup and Replication v8 for 1 year for my home-lab and I’ve been giving it a try. I like it quite a bit thus far and I might very well push for it at my work so we can have outstanding backups!!!!!

Here is a link to a video on the product:

What’s new in v8 YouTube Video

Here is a description of the product:

#1 VM Backup for VMware and Hyper-V

Veeam Backup & Replication™ is much more than backup – it provides fast, flexible, and reliable recovery of virtualized applications and data. We bring backup and replication together in a single solution to reinvent data protection and deliver the #1 VM backup for VMware vSphere and Microsoft Hyper-V virtual environments.

Availability for the Modern Data Center

Organizations are modernizing their data centers in order to provision IT services faster, strengthen security and control, and lower operational costs. While building modern data centers, organizations invest in server virtualization, modern storage applications and cloud-based services. However, businesses are facing new demands from end users including access to data and applications 24/7, no patience for downtime or data loss, and exponential data growth at 30-50% per year.

This opens a gap—an availability gap—between the requirements of the Always-On Business™ and IT’s ability to effectively deliver availability. Veeam® bridges this gap by providing customers a new kind of solution—Availability for the Modern Data Center™, which delivers recovery time and point objectives (RTPO) of < 15 minutes for ALL applications and data.

Veeam’s award-winning technology delivers:

Recovery of failed VM in as little as 2 minutes

Near-continuous data protection with built-in replication

Fast, agentless item recovery and e-discovery for Microsoft Exchange^ENHANCED!, SharePoint and Active Directory, along with transaction-level recovery of SQL databases

Lower RPOs and 20x faster backups with backup from HP and NetApp storage snapshots

Automatic recoverability testing of every backup and every replica, every time

Offsite backups 50x faster than standard file copy with built-in WAN acceleration

Fast and secure cloud backups with Veeam Cloud Connect

Deduplication and compression to minimize storage consumption

Offsite recovery with 1-click site failover and support for facilitated data center migrations with zero data loss

CompTIA Storage + Exam September 12th and Project + on the 19th!!!!

So I’m adding pain to misery to my certification madness. Since CompTIA announced that on Jan. 15th 2015 they will be discontinuing Storage + and I’ve always wanted it I’ve added the Storage + exam prep to my Cisco ICDN2 study time as-well.

So since I’m a man of goals and pushing my knowledge, I’ve schedule the exam for the 19th of September. I’ve finished Nigel’s book on the subject and now I’m doing Pluralsight and CBT Nuggets video review leading up to the exam.

Adding pain to insult and doing Project + on the following weekend.

On a side note my ICDN2 exam is October 24th.

My goal is to have the Storage + and CCNA: R&S done by the end of the year.

VMware vExpert 2015!!!!

I got the VMware vExper 2015 award for being an active member of the VMware community. Looking forward to offer whatever I can to people that have questions as always with a helpful and kind personality.

This is what happens when I free-time and a vision ;-)

Nuff said….

Monthly Update: May 2015

6/3/15

So I’m going to do something new for my blog and that is to at-least make monthly updates to my progression for the month.

This month has been busy I’ve been studying like a banshie for the CCNA exam while at the same time work on a project at work. I’ve schedule my exam for the 29th of June, now that the massive work-project, explained below, is done and I’ve been re-focusing on my studies. On a non-technical note I completed a 22 mile hike around Bear Mountain, CT on the weekend of 16th of May and that was pretty amazing.

Picture from hike:

(Typically I’ve seen a project of this scale done by a few engineers but I was able to do it all solo and without a problem. It’s something I give credit to my home-lab cause I was able to visualize both mentally and physically which allowed me to plan it out accordingly and if I ran into problems with the production environment I just brought it home to the home-lab and troubleshooted it at home.)

The project at work entailed the following hardware/software/consolidation:

1. (2) new Dell R700 series servers on Dual Xeon HT-enabled processors with 128 GB’s of RAM each with 8 gigabit nics w/ internal flash for ESXi 5.5.

2. Equalogic 4100S SAN with 18 TB’s in a RAID 10.

3. (2) Dell N3048 L3 switches in a super-stack for iSCSI/vMotion only traffic – completely separated from production.

4. (6) Dell N2048 switches in a super-stack to replace a aging Dell 2824 switching fabric for production. This also has employed over 5+ vLAN’s now compared to the previous solo flat /24 subnet.

5. 195 minutes of APC UPS backup runtime with Network Shutdown 4.0 remote shutdown module for a DR-power-outage scenario with email alerts for a controlled-monitored shutdown if needed.

6. Network re-cabling of CAT5e and fiber uplinks for the entire network replacing aging CAT 3/5 drops w/ proper punch-down placement and cable management.

7. Employment of a complete VMware Data Center platform with ESXi, vCenter, vCops, VUM, svMotion, vMotion, comprehensive snapshots both virtually and on the storage array, along with use of Backup Assist for backups of the VMware assets.

8. Complete Server Physical-to-Virtual Migration of all server assets with a redundant solo DC “outside of cookie jar” setup for domain fault-tolerance with a an affinity rule for ‘Core’ servers to live on the same host for inter-vSwitch performance benefits.

Benefits of the Project

1. Consolidation of server assets into a centrally managed infrastructure which now allows for greater ease of administrative/resource management, aggregated performance and disaster recovery.

2. Server “right-sizing” for all servers to adjust for higher resources pools which resulting in a 50% performance increase across the board.

3. With the deployment of a SAN for storage, we gained the performance of a centralized array for all servers to access which resulted in a 46% increase in IO speeds for high-demand servers such as our ERP application and SQL databases.

4. With a properly designed network infrastructure broadcasts and security are controlled now with the proper deployment of vLAN’s and ACL’s as-well as performance increases from network segmentation that now all now lives on a 228 Gpbs throughput core switching fabric. The network re-design coupled with the network re-cabling improve network performance drastically from proper placement of cabling away from EMI and the removal of aging CAT 3/5 cabling.

5. Cost savings, by reducing the server footprint we’ve reduced out power costs of the 20+ servers into just a few servers while at the same time reduced our cooling needs.

6. Stability, with the entire server infrastructure we’ve been able to maintain a higher up-time that previously achieved which is amazing coming from a company that in the past was accustomed to daily server crashes which equated into lost revenue.

Overall the month of May was an amazingly fun and busy time for me. I loved every bit of it when it came to doing the project as-well as my CCNA study. When I got done with the project I stepped back and it hit me; “I did it”, I completed the project from start (design/planning) to finish (implementation/configuration/administration) all by myself without any outside help. To me that feeling of achievement was amazing that with my commitment to my certifications and home-lab/self-study I was able to do this project without any problems at all. This just proves to me that I’m doing the right things with my career and I look forward to a promising future. 🙂

I’d like to say a special thanks to the guys/gals over at Techexams.net; your invaluable insight into my questions has been hands-down essential, and I’d like to thank my co-worker Juan Ayala for being super supportive, also for my parents and friends who said I was estranged from them but in-fact I was just dedicated to completing the project.

VMUG Advantage 2015: $2400 worth of software for $200!

2/8/15

Once again being a very active member of the www.techexams.net community I have discovered VMUG. VMUG is a user-based group that focuses on the areas of VMware and it’s solutions. I joined the network and 3 weeks ago I purchased the VMUG Advantage subscription and to my amazement this year VMware is offering the following software for home-lab users:

Included products are:

VMUG Advantage: link

Well one of the neat things they did recently is now the subscription allows me to use 3 hosts with up to 6 CPU’s and unlimited cores. So…… now my home cluster can have Enterprise Plus licensing with vCOPS and vSAN. I still have enough for a 3rd host later on down the road if I choose to get one for even more testing.

One of the things I really like is vCOPS and what it shows you in one pane of glass. The feature of this solution really help for complex and large datacenters. I’ve been using at work and the centralized management of my cluster is amazing. it makes vCenter look like a walk in the park. At some point I will test on vRealize but for right now I’m having way too much fun with the vSphere 5.5 w/ vCOPS and vSAN in my QNAP Ts-420 IP SAN in the home lab.

I’m really quite excited that VMware is doing this technet-oriented subscription for VMware. I like home-labbing and spend over 20+ hours a week invested into labbing with VMware, Cisco, Microsoft, and Sonicwall technologies and having a licensed and fully working VMware cluster really helps replicate a Enterprise grade network as close to the real deal as can be physically possible. I’m looking forward to now cramming these existing twin Dell R610’s with 64 GB’s of RAM and fully utilizing there benefits to a home cluster…..

My only problem now is I need to expand my home network out of a /24 into a /23 or use multiple vlans for all my VM’s and projects, lol! – Never thought that would happen!

Below is my vCOPS for my home lab, and without this solution I would have never been able to see that my VM’s are over provisioned.

VCP5-DCV in the bag….

Whelp it was a long study but after 5 months of study I’ve completed the VCP5-DCV course study and passed the exam on January 5th 2015. Since taking the ICM class at Stanly College in Locust NC back in October of 2014 I was basically living in my home-lab 5 hours a night during the week and about 10 hours on weekends and working with VMware 5.5 on a daily basis on the job at customer locations. I was actually kind of shocked by getting into the ICM class back in September and kind of pissed, I was literally 3 weeks from taking my CCNA:R&S exam but I had to shift gears and move into the VMware track…

In-fact in the month of December I did 10 full VMware ESXi 5.5 deployments sporting Dell R720 servers, Dell Equalogic SAN storage, HP/Cisco/Dell Switches for both iSCSI and FCoE as-well as deploying networking fabric to enhance the capabilities of customer networks. It’s been a blast and it really helped me pass the exam, also knowing that customers server infrastructure is state of-the-art! …But this kind of stuff is what I like doing…

I really underestimated the complexity of the exam and how hard it really was, but I managed to pass it. I really enjoyed working with VMware’s vSphere and vCenter products so this was quite the achievement for me personally (once I’m done with my next 2 certifications I’ll probably tackle the VCAP5-DCA) and furthermore how this product suite can truly make for a better working environment for pretty much any IT infrastructure that doesn’t yet utilize visualization. The features it provides your classical IT design strategy really helps a IT department sleep better; this is all coming from a IT person like myself that dealt with IT before the use of visualization.

The VCP5-DCV exam was hard, but now I’m getting back on the bandwagon and pressing onward and back on-track towards my Cisco Certified Network Associate: Routing and Switching (CCNA: R&S) since I’ve been using Cisco for a few years now but I want to get certified in networking and Cisco has the networking sector by the balls. My goal is to be CCNA:R&S certified by the end of March 2015. My overall goals for 2015 are to get my CCNA:R&S and my MCSA, if I have time the CCNA: Security.

Now some of you may-be like wow you have a pretty extensive lab; well I do but there is a method to my madness. I wanted to get my CCNA:R&S 1st but fate had a different route and I got my VCP5-DCV 1st so now I’m getting back into Cisco, once I get my CCNA:R&S I’ll pursue my MCSA. See this lab may-be extensive but it’s many solutions built into one package, that package is as close to a enterprise network as can be done.

Currently my VMware cluster has 2 different forests being used on two of the vLAN’s in the Cisco lab, this mimics two different Windows Domains and VMware datacenters and since this Cisco lab is setup to be isolated, the domains never leave the Cisco lab but the vCenter appliance is linked to a management network connected to my home LAN so I can manage them as if I had access to both networks, it seems complicated but it’s really not, we not for me at-least. See it may not be a very large scale deployment but its the practice that makes perfect I always say.

Below is a picture of my current Cisco Lab Topology for those that are curious:

Key:

1) the dotted squares represent network boundaries or vlans

2) The red lines are the production/management vlans

3) the green lines are for iSCSI/vMotion/svMotion only traffic.

Trevor’s Personal Blog

Welcome!

I figured since I like posting my labs and all I figured I’d make a blog for my VMware/Cisco/Microsoft Pursuit. – Right now the blog is being updated as I move along in my studies.

This is a work in progress. I’ll be adding content along the way.
