Assigning more vCPU’s to a VM may not necessarily increase CPU performance of a VM. Here are some best practice recommendations.
- Start with one vCPU per VM and increase as needed.
- Do not assign more vCPUs than needed to a VM as this can unnecessarily limit resource availability for other VMs and increase CPU Ready wait time.
- Performance degradation may occur on multiprocessor VMs in which the number of vCPUs was greater than the number of vCPUs in a NUMA node. Generally, try to keep multiprocessor VMs sized so that they fit within a NUMA node. In PvDC this would be (1, 2, 4, 6, and up o 8vCPU).
CPU Ready is a measure of the time a VM has to wait for CPU resources from the host. The larger the number of vCPU, the longer a VM may have to wait for resources from a host. This may result in performance degradation. A VM with lower vCPU will perform better than one with high vCPU.
Co-stop – VMware schedules all the vCPUs in a VM at the same time. If all the allocated vCPUs are not available at the same time, then the VM will be in a state of “co-stop” until the host can co-schedule all vCPUs. In its simplest form, co-stop indicates the amount time after the first vCPU is available until the remaining vCPUs are available for the VM to run. Sizing VMs to use the least number of vCPU’s possible minimizes the time needed for co-stop waits.
You are a party of 4 at a restaurant and there are only 16 places to sit in the whole restaurant. You come in and tell the host/hostess that there are 4 of you and you want to sit together. The hostess promptly informs you that there are not 4 seats available and you’ll have to wait. While you are waiting, 3 people get up. Your party can’t sit down because there are only 3 seats, but the couple that just came in behind you can take 2 of those seats since that is all they need. This continues to happen: 2 get up, 1 sits down, 3 get up, 2 sit down.
Throughout the whole time you are waiting for those 4 seats to open up while watching everyone else eat and enjoy their food.

One of the most important assets to your company is your intellectual property, your data.
Often, it is taken for granted until it is gone: A Ransomware Strike.
How did this happen? Often ransomware infects your computer when you open an attachment in a dubious email or click a suspicious link on the web. Other forms need no human interaction and simply probe vulnerabilities on your perimeter network until they find a way in.
Ransomware is a huge problem if you are not prepared for it. Remember to stay vigilant. If something looks suspicious it probably is. It is better to delete something than risk opening it. Also, keep your computers patched with the latest updates from Microsoft, keep antivirus software updated, and maintain current backups – offline if possible. If you are infected, shut down immediately and contact us at 888-499-0862. We will be able to assist in finding the source of the incursion for remediation and restoration your backups.
If you want a Net3 Engineer to evaluate or re-evaluate your current backup solution, we’d be happy to take a look and assess any vulnerabilities your company may have. The last place you want to find yourself is in the position of having to pay a ransom. Contact us for more information or assistance at 888-499-0862 or email@example.com.
There are a lot of attractive cloud deals out there.
1¢ a gig here! Free Tier 1 services here! Being that the cloud market is still a low tapped resource and relatively new for most businesses, it’s so easy to click “Buy Now”, enter the business credit card and take advantage of these great offers. But when you look at the fine print, are these really great offers?
Bottom line: nobody operates at zero in the cloud. If you think that you are going to do so, you are sorely mistaken. Larger, public cloud entities do a great job advertising low rates but there tends to be a little “bait and switch” going on. Putting your data in the cloud for 1¢ a gig only to pull it out for 8¢ a gig is not what I call a low cost service. 100 Terabytes = 100K gigs = $1000/month. Moving this data – and you WILL have to move it – would cost $4000. Retrieving data shouldn’t feel like a penalty or tax, but that’s exactly what it is and it’s locking businesses in a place where they probably don’t want to be permanently.
To be clear, the companies that do this are not being deceitful. Everything is outlined in the End User Licensing Agreement documentation, but we live in a EULA desensitized world. Does anyone really read the fine print with a fine toothed comb anymore? If you are that someone and you happen to catch this, how likely are you going to negotiate better terms? How likely is the large cloud company going to agree to these terms? I don’t know the answer to these questions, but it does shed questionable light on the current large cloud provider landscape.
The good news: There are smaller, viable, consultative cloud providers out there that offer great service with low cost rates. It’s worth researching and though it may take a little more time to determine which cloud partner to work with, it’s definitely worth it. There is a time and place for the big cloud providers, but it’s not for every season nor every workload. Utilizing a tool like PvDC Cloud Management Portal by Net3 Technology, Inc. is a great option for businesses: it gives flexibility for utilizing best of breed cloud services including AWS, Google and vCloud Air for when the time and need is right.
If you dove into the Large Cloud Provider pool and now are drowning in regret, you can get yourself out. It may cost a penny (or a lot of pennies) to be saved, but your businesses data is worth saving and it can be put in the right place at the right cost. Contact Net3 Technology, Inc. where our cloud experts will lead you in the right direction and will support your cloud journey 24/7/365.
A 4 Step Guide for your Disaster Recovery plan
True Disaster Recovery is taking data from one site to another where it will be safe and separate from the event you encounter. There are many factors that separate a great DR plan from good one such as infrastructure, cloud provider, replication technology, cost, etc. Though every business prioritizes their plan differently, this checklist is essential to make sure your DR plan is the best it can be for business continuity:
- Define what applications need to come up first. What would cripple your business through the course of an event, should be top priority.
- Define the RTO’s and RPO’s of ALL your applications. If you need assistance with this, here is a resource that can help and we are happy to help you through this process as well.
- Test the functionality of your apps. Just because it’s running, doesn’t mean it can process transactions all the way through or work exactly as it should. Don’t forget to test the connectivity to your DR site too!
- Decide how and what you are going communicate with your employees and customers during a real-life event.
If you haven’t tested your plan in 6 months, it’s time to do so. The technology behind PvDC Cloud allows you to test quickly and as many times as you want. Using PvDC for DR also allows you to get your data back on prem as easy as it was to fail over – no lock-in here. Customer support is one of the pillars of our business and we’d be happy to assist in any way. Contact us today if you have any questions or concerns with your DR plan.
Zerto and Net3 Partner to Protect your Business
Hundreds of thousands of organizations around the world leverage virtualization technologies to deliver their IT services and applications on scalable and efficient platforms. Regardless of the virtualization platform, the same key challenges of implementing a complete business continuity plan and disaster recovery strategy for virtualized applications remain.
Can your organization:
• Maintain simplicity of DR across multi-hyperisors, clouds, and storage platforms?
• Replicate protected virtual machines with a technology engine that is aligned with all the benefits of virtualization?
• Minimize data loss through low RPO’s via continuous data protection?
• Orchestrate and automate disaster recovery processes to deliver an RTO of minutes?
M33 Integrated could thanks to Net3’s native integration of Zerto into their Business Recovery Service. Here is a success story of how we helped M33 Integrated, now known as Transplace, fail over 127 servers in minutes without disruption to their end users and more importantly their customers.
Lets go beyond the same old conversation about “what is your disaster recovery plan?” The conversation should be centered around the details of creating a critical offsite application recovery plan that actually works without creating burden on your stretched IT team or budget. Contact us so we can show your business how we solve the issue of business resiliency today.
