Exchange 2010-2016 Database Availability Group (DAG) cluster timeout settings for VMware

Symptom:

Exchange 2010-2016 Database Availability Group (DAG) active database moves between DAG nodes without any reason, when the DAG nodes are VMware Virtual Machines. This may be due to the DAG node being VMotioned by vSphere DRS cluster.

Solution:

The settings below allow you to VMotion without DAG active databases flipping between nodes for no reason.

Although the tip below is mainly useful for Multi-Site DAG clusters, I have seen this flipping happen even within the same site. So, the recommendation is to do these commands on ANY DAG cluster that is running on VMware.

Instructions:

Substitute your DAG name for an example DAG name below, yourDAGname or rpsdag01.

On any Mailbox Role DAG cluster node, open Windows PowerShell with modules loaded.

Type the following command to check current settings:

cluster /cluster:yourDAGname /prop

Note the following Values:

SameSubnetDelay

SameSubnetThreshold

CrossSubnetDelay

CrossSubnetThreshold

Image

Type the following commands to change the timeout settings.

cluster /cluster:yourDAGname /prop SameSubnetDelay=2000

cluster /cluster:yourDAGname /prop SameSubnetThreshold=10

cluster /cluster:yourDAGname /prop CrossSubnetDelay=4000

cluster /cluster:yourDAGname /prop CrossSubnetThreshold=10

Image

Type the command to check that settings took

cluster /cluster:yourDAGname /prop

Image

You ONLY need to run this on ONE DAG node. It will be replicated to ALL the other DAG nodes.

Slides from my session at the BriForum 2014 conference

YuryMagalif_BrianMadden_03Thank you to those who attended my session at BriForum 2014 in Boston and filled out the survey!

This is my 2nd year speaking. I hope to be back next year.

Here is the session presentation slide deck:

AgentlessAntivirusTips&Tricks_YuryMagalif_July2014_BriForum_v3

Here is the link to the session description on the BriForum website:

http://briforum.com/US/sessions.html#tipstricks

This year, the conference in Boston was excellent. I got a chance to meet Brian Madden (pictured at left), Gabe Knuth, Jack Madden and the TechTarget crew. In addition, I met many amazing people who are the top experts in End-User Computing –Benny Tritsch, Shawn Bass, ProjectVRC team: Jeroen van de Kamp, Ryan Bijkerk & Ruben Spruijt.

In particular, Benny and Shawn’s HTML5 comparison session and ProjectVRC comparative testing session were the highlights of the conference for me.

In my own session, I was successful with a demo of McAfee and had a good number of questions from the audience.  Stay tuned for the video, coming in August of 2014.

My presentation is called “Tips and Tricks on Building Agentless Antivirus Scanners for VMware View Virtual Desktops”

This tips and techniques session is best for administrators and consultants looking to implement an Antivirus solution for their VMware Virtual Desktop Infrastructure (VDI). The goal is to minimize I/O impact to VDI. We will discuss the two most developed scanners taking advantage of VMware vShield Endpoint application programing interfaces (APIs), Trend Micro Deep Security Antivirus 9.0 and McAfee Agentless MOVE AntiVirus 3.0. New this year is the discussion of VM-based scan policies. Overall, we will focus on real-world examples of VMware, Trend Micro and McAfee best practices. For example, the participants will learn whether to use their current Antivirus for VDI versus VDI agentless antivirus, why the VM Communication Interface (VMCI) driver is important, how to deploy the Security Virtual Appliances (SVAs), why you should disable VMotion for SVAs, how to test your solution using EICAR test files and how to shut down your VDI agentless antivirus VMs properly if doing maintenance. A basic understanding of VMware vSphere, VMware View and Enterprise Antivirus solutions is recommended.

Attendees will learn:
• How to minimize AntiVirus scanning I/O impact to VDI
• Whether to use your current AntiVirus versus VDI agentless Antivirus
• How to pick the best AntiVirus vendor for your environment
• How to test your agentless AntiVirus for effectiveness using EICAR files
• How to deploy and maintain your Trend Micro or McAfee infrastructure

Please send me any remaining questions that come up.

Virtual Desktops (VDI) on an Airplane

Recently, while flying on United Airlines I noticed the WiFi sign on the seat in front. I never used WiFi on planes before, so I thought it would be expensive. Imagine my surprise when it was only $8.99. It was probably cheap to compensate the absence of TV displays.

I immediately thought of our CDI Virtual Desktop (VDI) lab in Teterboro, NJ (USA). Would the Virtual Desktop even be usable? How will video run? I connected immediately, started recording my screen and opened my Virtual Desktop. It worked! Everything except video worked well.

My idea came because of Michael Webster, who has already tried doing this and wrote about it. I also wanted to do it in the Gunnar Berger style of protocol comparison. So, for your viewing pleasure — Virtual Desktops (VDI) on an Airplane.

——

Description:

This video is a demonstration of the Virtual Desktop (VDI) technology, located at CDI in Teterboro, NJ (USA) being accessed from an airplane 34,000 feet (10 km) high. Virtual Desktops allow you to use your Windows desktop from anywhere — even on satellite based WiFi. You will see PCoIP and HTML5 tests, Microsoft Word, HD video, YouTube video and vSphere client utilization.

Demonstration: Yury Magalif.
Lab Build: Chris Ruotolo.
Date: June 7, 2014
Connecting From: Random clouds above Missouri, USA

Equipment and Software used:

VMware View 5.3.
VMware vSphere 5.5.
Cisco C-series servers.
EMC XtremIO all flash storage array.
10Zig Apex 2800 PCoIP acceleration card with a Teradici chip.

I am very grateful that you keep coming to hear what I have to say and hope to be back next year.

My presentation is called “TB3306 – Tips and tricks on building VMware vSphere 5.5 with BladeSystem, Virtual Connect, and HP 3PAR StoreServ storage”

Returning for the sixth year in a row, this tips-and-techniques session is for administrators and consultants who want to implement VMware ESXi 5.5 (vSphere) on HP c-Class BladeSystem, Virtual Connect, and HP 3PAR StoreServ storage. New topics will include the auto-deployment of domain configurations and Single Root I/O Virtualization (SR-IOV) for bypassing vSwitches. The session will focus on real-world examples of VMware and HP best practices. For example, you will learn how to load-balance SAN paths; make Virtual Connect really “connect” to Cisco IP switches in a true active/active fashion; configure VLANs for the Virtual Connect modules and virtual switches; solve firmware and driver problems. In addition, you will receive tips on how to make sound design decisions for iSCSI vs. Fibre Channel, and boot from SAN vs. local boot. To get the most from this session, we recommend attendees have a basic understanding of VMware ESX, HP c-Class BladeSystem, and Virtual Connect.

VMware announces VSAN to be released around March 10th.

ben fathi vsanBen Fathi, the CTO of VMware announced the Virtual Storage Area Network (VSAN) feature in vSphere ESX on March 6, 2014.

VSAN is a storage technology that pools all local disks on multiple servers into one large distributed volume. Caching is done via an SSD drive.

Unfortunately, licensing and pricing details get released at VSAN General Availability around March 10th.

Out of the door, the VSAN will have the following features:

  1. Full support for VMware Horizon / View (no VSAN inside View — yet)
  2. Up to 32 nodes.
  3. Up to 2 million IOPS.
  4. 4.5 PB of space.
  5. 13 VSAN Ready Node configurations at launch using Cisco, IBM, Fujitsu or Dell servers.
  6. Build your own supported.

However, VSAN will also have the following requirements:

  1. At least 1 SSD drive.
  2. Up to 7 mechanical drives.
  3. Cannot use all SSDs or SAN storage.
  4. SSD must be at least 10% of space.
  5. Need ESXi 5.5 Update 1.

VSAN competitors:

  1. EMC’s ScaleIO — can build distributed storage on any OS out there (Windows, Linux plus VMware) and more nodes (per Duncan Epping).
  2. Nutanix — server, storage, VMware in a customized box.
  3. Simplivity — same concept as Nutanix.
  4. Pivot3 — same concept as Nutanix.
  5. Virtual Storage Appliance (VSA) solutions (VMware own VSA, Atlantis, HP Lefthand VSA, etc.).
  6. Regular storage arrays.
  7. Flash only storage arrays (XtremIO, EMC VNX-F, Cisco’s Whiptail/Invicta)

Analysis:

There is a lot of interest in VSAN. The beta had more than 10,000 people sign up. Some VMware partners around the country are preparing solutions already, ready to sell to eager customers.

However, everything depends on how it’s licensed and priced. The price has to be lower than traditional storage and even VSA solutions (except maybe VMware’s VSA). Only then it will make sense for the smaller customer.

Otherwise, especially for lower end Virtual Desktop Infrastructure (VDI), the VSAN is perfect — easy to set up (one checkbox), minimum of only 3 servers, provides enough IOPS with SSD caching. We are planning to use it for VDI.
