Synchronous and 1-to-many Replication

Greetings,

I usually blog about APIs, but today I want to point to 2 excellent videos showcasing Tintri’s Tintri Global Center (TGC) GUI. One is on Synchronous Replication and Failover; and the second one is on 1-to-many replication.

Tomer Hagay first reviews the Synchronous Replication configuration which uses Tintri’s Service Groups. Next, he shows all the statistics that are available; for example, the VM latency components: host, network, contention, flash or disk, and mirror. Finally, Tomer shows how easily it is to do transparent failover.

Bill Roth first demonstrates how to find the VMstores’ replication information. Next, he shows how to get protection information for VMs.  How to add a new replication link to a VM is shown. A VM can replicate up to 4 different destinations. Of course Service Groups can have 1-to-many.replication too. As you know, one of the cool things about Tintri, is that Tintri has statistics; and in this case, Bill shows the two replication statistics that are available:  MBytes Remaining to to be replicated, and Replication Rate, both logical and network.

So check out these informative videos and enjoy Winter Solstice,

Tintribot Is Here to Help

Greetings,

As you might recall my post on Using Tintri APIs to Build Tintri Anywhere discussing using Slack as a management interface.  We now have 2 videos on Tintribot as an example. Please note that this is a possible future.

The first video, Manage storage with ChatOps from Tintri between bites, features an admin, Krystle, approving a recommendation from our VM Scale-out feature.

In the above video, Tintribot has code that can read VM Scale-out recommendations and approve them which is covered in this Tintri post. More VM Scale-out code can be found in this post.

The second video, Manage storage from anywhere with Tintri ChapOps, has admin Krystle bringing up VMs and putting production data on them..

First Tintribot brings up 500 VMs using Tintri cloning. Then the bot uses SyncVM to sync the 500 newly created  VMs to the latest recovery point of the production SQL data.

So how do you manage your storage?

Changing QoS during Veeam Backups

Tintri’s QoS is a great tool to limit storage bandwidth per VM, but what happens when a backup occurs?  Well, QoS will also limit your backup storage IOPS. If this is an issue in your environment, you might consider clearing the QoS during backup.

As an example of clearing QoS when a backup occurs,  a PowerShell script is now available that interacts with Veeam Backup and Replication.  The script, Veeam_Backup_Tintri_QoS.ps1 is available on GitHub.  The file, README.md has the information needed to run the script.

Basically the script polls the Veeam backup server every 10 seconds. When a Veeam backup job has started, the script finds the associated storage.  If the storage is on a VMstore and QoS is set, then the QoS is cleared.  After the job is done, the script restores the QoS settings.  A TGC server is required since the script connects only to a TGC.

Below is a diagram of Veeam_Backup_Tintri_QoS.ps1 (Backup Script) running in the Veeam backup server.

.veeam_tgc_diagram

However the backup script could be in a separate VM.

This script could possibly be used as a template for other backup vendors.  Results may very.  Veeam made it straight-forward with a PowerShell plug-in.

Until next time,

Automation, Cloud, Containers, and PySDK

Greetings,

November has started with a bang of announcements and publications:

  1. Tintri Raises the Bar for Enterprise Cloud Build on Web Services Architecture and RESTful APIs” discusses Tintri’s architecture, automation, container support, analytics, and public cloud integration.  There will be a webinar on November 10th at 11 am Pacific with Kieran Harty and Steve Herrod.
  2. The Register’s article on Tintri’s Chatbot , automation, cloud, and container support talks about Tintri’s Web Services approach that makes everything API-accessible which makes automation , container support, public cloud integration, and chat-bot possible.
  3. ComputerWeekly.com published an article of “Tintri adding VMware and Flocker persistent container storage” which discusses Tintri’s container Flocker support in more detail.
  4. Tintri announced the release of the Python SDK (PySDK). This PySDK was used in the above mentioned chat-bot. With PySDK, Tintri will be able to integrate easier with automation platforms like OpenStack.
  5. Tintri published a white paper on Tintri’s vRealize Orchestrator Plugin. Now VMware’s vRealize orchestrator can manage Tintri storage.  This allows scripts in vRealize to invoke Tintri management APIs.

This is just the beginning of Tintri’s cloud announcements.  More will be coming in the next months.  Until next time,

Using Tintri APIs to Build Tintri Anywhere

Greetings,

We have a customer in Japan, Adways, the used Tintri APIs, to build a Slack-bot than communicates with a Tintri VMstore.  A Slack client sends a command message to the Slack server just like messages are sent between people.  The Slack server sends a message to the Tintri bot that invokes the appropriate Tintri API.  See the picture below:

adways_slackbot_api

This allows the VMstore to be managed by a cellphone. Here is an example:

@tintribot:tintri tintri-001 show appliance_info

The result output is:


+-------------+--------------------------+
| Info        | Value                    |
+-------------+--------------------------+
| Product     | Tintri VMstore           |
| Model       | T540                     |
| OS version  | 3.2.2.1-6163.33224.16186 |
| API version | v310.21                  |
+-------------+--------------------------+

If this interests you, please check out Masaaki Hatori’s blog. I had to use Google Chrome to translate it from Japanese to English.

PowerShell 2.5 Toolkit Released

Greetings,

It has been a while since I have posted. While I’ve been on vacation and catching-up, my colleague was working on a new Tintri Automation Toolkit for PowerShell 2.5. Today it went up on Tintri’s support site for your downloading pleasure. If you haven’t visited the support site in a while, you’ll notice that it has changed. Once on the support download page, find “Tintri Automation Toolkit 2.5” and click on it. An information frame will appear on the right. Click on “Download MSI” to download the new toolkit.

The major features are:
• Upgrade VMstore(s) given the RPM file
• Configure appliance settings (Data IPs, DNS, Autosupport, Alerts)
• Configure Hypervisor Managers on a VMstore
• Set Service Group QoS
• Support for SyncVM File-Level-Restore
• Manage VMstores on a TGC
• Set quota on SMB shares
• Support for PowerCLI 6

A more information is on my Tintri blog. For me, the top 3 features are: Tintri command search, setting QoS in TGC Service Groups, and updating VMstores from a downloaded RPM file.

Let me know if you have questions, or have coded new scripts you want posted on our GitHub site.

Cheers,

Tintri Automation Toolkit 1.5 Released

The Tintri Automation Toolkit version 1.5 is now released.  The Automation Toolkit allows you to manage Tintri VMstore and TGC using PowerShell.  It can be obtained from Tintri Support download page under the “Download” tab, and you need a login.

The Automation Toolkit QuickStart Overview Guide can be downloaded from Tintri Support download page under the “User Guides” tab.  Scroll down to “3/2/2015 entry: “Tintri Automation Toolkit Quick Start Overview Guide”.  The guide lists all the PowerShell cmdlets, discusses how to get help and authentication, and has code samples.  See my previous PowerShell post for pictures on how to download.

The 1.5 version highlights are:

  • Hyper-V VM management
  • Delete Snapshot
  • SMB Share management
  • Support v310 Tintri API servers (as well as v300)
  • View datastore level statistics from TGC 1.1
  • On-line help improvements

Just like VMware VMs can be piped to Tintri cmdlets, so can Hyper-V VMs be piped to Tintri cmdlets.  This is what it means to be virtually aware storage.

Tintri Automation Toolkit examples are now being posted on GitHub.  Check-out the following examples that demonstrate the new features:

Over time, more PowerShell examples will be added, so check periodically.

Enjoy the new features,
