During Tech Field Day 11 we had presentations from a lot of awesome companies. Some of them I knew, but others were new to me, and that while some of these already exist for multiple years. The first of these “older”companies was Netwrix.
When writing a couple of VMware designs in which compliancy was a big deal, I learned that a good auditing tool is a must have as the auditors will not approve anything if they you didn’t provide them with the right answers and tooling needed to be compliant. A tool like Netwrix can help a lot with this.
So during Tech Field Day 11 I was pleased to see Netwrix do a great job at explaining where they came from and what they do. A couple of points that were told in this first presentation:
• The company is founded in 2006 (that’s right the company celebrates it’s 10th anniversary this year)
• The founders Michael Fimin and Alex Vovk, who both worked at Quest software before starting Netwrix.
• The company has no venture funding.
• The company has over 200 employees across the globe, and;
• They have over 7000 customers worldwide
But it might be better if you just watch part 1 of the presentation first:

Netwrix Auditor Platform capabilities
The Netwrix auditor platform can help you audit and monitor multiple systems and application, the following are usable by default:
- Microsoft Active Directory
- Microsoft Exchange Server
- Microsoft Office 365
- Microsoft Sharepoint
- Microsoft SQL server
- VMware vSphere
- Windows File Server
- Windows Server
Some of these are on-premises only, but a couple of them are also hybrid cloud capable, meaning you can audit your applications both on- and off-premises. Through the use of RESTful API’s both in and out bound you can leverage even more, but that is for a later blogpost :D.
Other TFD11 delegates on Netwrix
As always a couple of my TFD11 delegates also wrote some articles on Netwrix. Here are the articles already in the open (I’ll try to keep it updated, but I can’t promise anything :D):
Julian Wood (@julian_wood) wrote a great preview, the Tech Field Day 11 Preview: Netwrix
As well as Alaister Cook (@DemitasseNZ) did an introduction: TFD11 introduction: Netwrix
A small section on Netwrix can be found in the write-up by Tech Field Day Goes To 11
And last but not least, Mark May () wrote a piece right after the presentation (showoff ;-P) called: Breaking down silos between security and operations
And as always, all Netwrix information and videos are available at the Tech Field Day site: Tech Field Day Netwrix
As already mentioned I’ll try to keep this post updated if people will write more on Netwrix, and I will also try to do a part two and three on Netwrix, but first I want to write a couple of post on other companies presenting at TFD11.
In half an hour we’ll go live with Storage Field Day 10. I do encourage you to watch live at the Tech Field Day site, but for those that really want to follow the livestream on vdicloud.nl, here you go:
The agenda will be as follows:
If you have a question you would like to be asked during the presentation, please do so (use twitter and use the hashtag #SFD10)
See you online!

VMware VSAN 6.2
On February 10 VMware announced Virtual SAN version 6.2. A lot of Metis IT customers are asking about the Software Defined Data Center (SDDC) and how products like VSAN fit into this new paradigm. Let’s investigate what VMware VSAN is, and what the value would be to use it, as well as what the new features are in version 6.2
VSAN and Software Defined Storage
In the data storage world, we all know that the growth of data is explosive (to say the least). In the last decade the biggest challenge for most companies was that people just kept making copies of their data and the data of their co-workers. Today we not only have this problem, but storage also has to provide the performance needed for data-analytics and more.
First the key components of Software Defined Storage:
- Abstraction: Abstracting the hardware from the software provides greater flexibility and scalability
- Aggregation: In the end it shouldn’t matter what storage solution you use, but it should be managed through only one interface
- Provisioning: the possibility to provision storage in the most effective and efficient way
- Orchestration: Make use of all of the storage platforms in your environment by orchestration (vVOLS, VSAN)
VSAN and Hyper-Converged Infrastructure
So what about Hyper-Converged Infrastructure (HCI)? Hyper-Converged systems allow the integrated resources (Compute, Network and Storage) to be managed as one entity through a common interface. With Hyper-converged systems the infrastructure can be expanded by adding nodes.
VSAN is Hyper-converged in a pure form. You don’t have to buy a complete stack, and you’re not bound to certain hardware configurations from certain vendors. Of course, there is the need for a VSAN HCL to make sure you reach the full potential of VSAN.
VMware VSAN 6.2. new features
With the 6.2 version of VSAN, VMware introduced a couple of really nice and awesome features, some of which are only available on the All-Flash VSAN clusters:
- Data Efficiency (Deduplication and Compression / All-Flash only)
- RAID-5/RAID-6 – Erasure Coding (All-Flash only)
- Quality of Service (QoS Hybrid and All-Flash)
- Software Checksum (Hybrid and All-Flash)
- IPV6 (Hybrid and All-Flash)
- Performance Monitoring Service (Hybrid and All-Flash)
Dedupe and compression happens during de-staging from the caching tier to the capacity tier. You enable “space efficiency” on a cluster level and deduplication happens on a per disk group basis. Larger disk groups will result in a higher deduplication ratio. After the blocks are deduplicated, they are compressed. A significant saving already, but combined with deduplication, the results achieved can be up to 7x space reduction, off course fully dependent on the workload and type of VMs.
New is RAID 5 and RAID 6 support over the network, also known as erasure coding. In this case, RAID-5 requires 4 hosts at a minimum as it uses a 3+1 logic. With 4 hosts, 1 can fail without data loss. This results in a significant reduction of required disk capacity compared to RAID 1. Normally a 20GB disk would require 40GB of disk capacity with FTT=1, but in the case of RAID-5 over the network, the requirement is only ~27GB. RAID 6 is an option if FTT=2 is desired.
Quality of Service
This enables per VMDK IOPS Limits. They can be deployed by Storage Policy-Based Management (SPBM), tying them to existing policy frameworks. Service providers can use this to create differentiated service offerings using the same cluster/pool of storage. Customers wanting to mix diverse workloads will be interested in being able to keep workloads from impacting each other.
Software Checksum will enable customers to detect corruptions that could be caused by faulty hardware/software components, including memory, drives, etc. during the read or write operations. In the case of drives, there are two basic kinds of corruption. The first is “latent sector errors”, which are typically the result of a physical disk drive malfunction. The other type is silent corruption, which can happen without warning (These are typically called silent data corruption). Undetected or completely silent errors could lead to lost or inaccurate data and significant downtime. There is no effective means of detection these errors without end-to-end integrity checking.
Virtual SAN can now support IPv4-only, IPv6-only, and also IPv4/IPv6-both enabled. This addresses requirements for customers moving to IPv6 and, additionally, supports mixed mode for migrations.
Performance Monitoring Service
Performance Monitoring Service allows customers to be able to monitor existing workloads from vCenter. Customers needing access to tactical performance information will not need to go to vRO. Performance monitor includes macro level views (Cluster latency, throughput, IOPS) as well as granular views (per disk, cache hit ratios, per disk group stats) without needing to leave vCenter. The performance monitor allows aggregation of states across the cluster into a “quick view” to see what load and latency look like as well as share that information externally to 3rd party monitoring solutions by API. The Performance monitoring service runs on a distributed database that is stored directly on Virtual SAN.
VMware is making clear that the old way to do storage is obsolete. A company needs the agility, efficiency and scalability that is provided by the best of all worlds. VSAN is one of these, and although it has a short history, it has grown up pretty fast. For more information make sure to read the following blogs, and if you’re looking for a SDDC/SDS/HCI consultant to help you in solving your challenges, make sure to look for Metis IT.

VMware to present on VSAN at Storage Field Day 9
I’m really exited to see the VMware VSAN team during Storage Field Day 9, where they will probably dive deep into the new features of VSAN 6.2. It will be an open discussion, where a I’m certain that the delegates will have some awesome questions. Also I would advise you to watch our earlier visit to the VMware VSAN team in Palo Alto about a year ago, at Storage Field Day 7 (Link)
