CTO Satyam Vaghani was kind enough to announce several new products and features relating to the future of PernixData at Virtualization Field Day 5. If you’re not familiar with PernixData, they got their start with their FVP product which provided server side flash for both a read cache or a write-through cache. I’ve used the product several times and it really does some amazing things to smooth out latency and can give your storage array some serious umph! ...

Last year I wrote a post on VMTurbo and its method of using the idea of a market economy to manage your infrastructure. If you need a refresher (or because you didn’t read my blog, shame) take a look here. If you aren’t going to read it, the gist is that VMTurbo monitors your virtual environment and uses the hardware as though it is a supply, and the workloads that run on it as the demand. Based on the demand of a workload and supply of a resource there is a cost associated with the workload, and VMTurbo uses these metrics to determine the most cost effective way to balance these. ...

I got up this morning to receive news that I had completed the qualifications for the VMware Certified Design Expert certification. This is a group of around 200ish individuals who have completed this exhaustive process which included three exams, submitting an enterprise design and then defending that design in front of a panel of other VCDXs. From the VMware education site: VMware Certified Design Expert (VCDX) is the highest level of VMware certification. This elite group is comprised of design architects highly-skilled in VMware enterprise deployments and the program is designed for veteran professionals who want to validate and demonstrate their expertise in VMware technology. ...

Last week was packed full of announcements since Microsoft Ignite and EMC World were two large trade shows happening simultaneously. One announcement that excited me was a free virtual storage appliance from EMC. The appliance has the same look and feel of a VNXe but is completely virtual. You know what that means? If you’re like me, you like to tinker with things in a lab environment so as to not destroy a critical production network. Also, if you happen to write posts on things like VMware Site Recovery Manager, you’ll want to have a storage array that can replicate to a second one. That leaves you with the Netapp Simulator or the HP StoreVirtual appliance unless you want to actually buy two storage arrays. (That ain’t cheap). Well, now we have the EMC vVNX. ...

Zerto has been a great product for companies looking to deploy an easy to use disaster recovery solution. One of the limitations of the product was that it only worked with VMware vSphere, but not any more. Version 4 just dropped and it’s got a myriad of new goodies. New User Interface Cross-Replication from vSphere to Microsoft SCVMM and Amazon Web Services (AWS) Sizing improvements More Secure Virtual Replication Appliances vSphere 6 support The most appealing new capability was the ability to fail over a vSphere environment to Amazon Web Services (AWS). This could save small businesses A LOT of money. Small businesses that have a disaster recovery requirement no longer need to have a dedicated co-lo and spend money on equipment when they may never use it. AWS provides compute, storage and network on an as-needed basis and most of the time, the disaster recovery site is not needed which correlates to savings. ...

Setting up a DHCP relay is a pretty common task that performed by network administrators when setting up a new LAN. If you’re not familiar with a DHCP Relay, take a look at the example below. In order for a client to get an IP Address from a DHCP Server, it sends out a broadcast once it’s plugged into the network. The broadcast is asking for any servers that are DHCP servers to reply. Remember that a broadcast is a frame that is forwarded to all hosts on a Local Area Network. The DHCP Server will reply and the client will get it’s IP Address. ...

The vSphere-land top virtualization blog voting is now over and theITHollow.com was voted #35 which is up from number forty last year. I wanted to take this opportunity to thank everyone who voted for the site. There are very few rewards for all the time that is spent posting content, but seeing that the hard work is benefiting others, and is useful to the community, are among the top for sure. ...

If you’re in the market for a Load Balancer and don’t mind that it’s virtual, check out Kemp’s Virtual Load Balancer. Even better is if you want to try stuff out in your lab because you can get the Virtual Load Balancer for free! There are some limitations, I mean everyone has to make money some how and theres no reason to buy the cow if you get the milk for free, am I right? ...

Many of my daily activities at work now revolve around the idea of a Hybrid Cloud so some of my home lab activities have also followed suit. I realized it had been a while since I wrote up the particulars of my home lab and I’ve added some equipment so this gives me a good opportunity to show some of the upgrades. Configuration The environment consists of four physical ESXi hosts that run most of my virtual machines. These servers have three nics that handle all of the virtual machine traffic and the NFS Storage traffic to a pair of Synology NAS devices. ...

There is a new kid in town when it comes to infrastructure monitoring. Opvizor is a pretty neat little solution for identifying issues in your environment before they become a problem. The install was simple enough, only requiring me to run an installer and connect it to my vCenter Server. Once that was done, it was a matter of clicking a button to scan and upload my data back to Opvizor’s servers (anonymized data of course). These uploads are scheduled to prevent all this manual nonsense, but I couldn’t wait to see what my environment looked like so I uploaded it right away. ...
