Tintri has announced the release of Tentri OS 3.0, Tintri Glocal Center 1.1 and Tintri Automation Toolkit. A copy of the press release is shown below.

Tintri Introduces New Generation of Smart Storage with Multi-hypervisor Support and Industry’s First VM-level Automation Capabilities

TINTRI OS 3.0, TINTRI GLOBAL CENTER 1.1 AND TINTRI AUTOMATION TOOLKIT DELIVER ADVANCED CAPABILITIES FOR MULTI-HYPERVISOR VIRTUALIZED ENVIRONMENTS AND PRIVATE CLOUD DEPLOYMENTS

MOUNTAIN VIEW, Calif.– August 14, 2014 – Tintri, the leading producer of application-aware smart storage for virtualization and cloud environments, today announced the availability of Tintri OS 3.0, Tintri Global Center 1.1 and Tintri Automation Toolkit. The new capabilities in these product releases enhance the industry’s only storage platform with VM-level operations for data management with multi-hypervisor support and end-to-end VM-level automation to accelerate virtualization and private cloud deployments.

“Much has been said about the strategic, operational and organizational implications associated with different cloud delivery models. While discussions about cost, security and application portability for public cloud are still raging, many large enterprises have decided to start their journey to cloud with private cloud. Whether it is on-premises private cloud or off-premises hosted cloud, there is a growing feeling that private cloud provides the most immediate onramp that enables enterprises to start reaping the benefits of the cloud based IT service model,” said Tim Stammers from 451 Research.

The new capabilities of Tintri OS, Tintri Global Center and Tintri Automation Toolkit provide a compelling and feature-rich foundation for private clouds based on enterprise virtualization.

“Virtual machines are at the heart of private cloud deployments, which demand a smart storage infrastructure that is simple to deploy and manage, self-tuning and responsive to dynamically changing workloads, and highly automated at the right unit of management: the VM,” said Ken Klein, Chairman and CEO of Tintri. “These are the defining characteristics of Tintri smart storage. Private cloud deployment is one of the fastest growing use cases for Tintri, and these new releases further enable customers on their cloud journeys.”

“We have a highly virtualized environment that requires both rapid updates and scaling, requirements that pose huge challenges for traditional storage. Tintri enables us to easily deploy and tear down virtual machines as needed by demand, drastically increasing the rate of change in cloud environments,” said a customer at the Department of Defense Cyber Range.

Key Capabilities of Tintri OS 3.0 include:

· Multi-hypervisor support

Tintri OS 3.0 adds support for Red Hat Enterprise Virtualization based on Kernel-based Virtual Machine (KVM). Support for multiple hypervisors enables customers to extend the benefits of Tintri smart storage to all of their virtualization environments and is a key requirement for moving to private cloud deployments. Customers can now deploy multiple hypervisors on a single VMstore.

“Red Hat Enterprise Virtualization is a major component of Red Hat Cloud Infrastructure, which enables enterprises to build and manage their own private cloud environments,” said Radhesh Balakrishnan, general manager, Virtualization and OpenStack, Red Hat. “Tintri’s support for Red Hat Enterprise Virtualization, via the new Red Hat Enterprise Virtualization 3.3 API, will provide Red Hat customers an on-ramp to deploy high-level functionality required for robust yet simple cloud computing services based on Red Hat Enterprise Linux OpenStack Platform.”

· RBAC and AD/LDAP integration
Tintri OS 3.0 also includes role-based access control and integration with Microsoft Active Directory and LDAP directory services, providing simple and powerful access control and authentication for a Tintri VMstore on a per user basis.

Key Capabilities of Tintri Global Center 1.1 include:

· VMstore monitoring and reporting

Enables administrators to monitor their VMstores from a cluster-wide dashboard and drill down to individual VMstore dashboards. VMstore-level performance and capacity monitoring along with up to 30 days of historical reports are available for trend analysis and troubleshooting. Users can view aggregated alerts management across VMstores from a single pane of glass.

· Data protection and disaster recovery monitoring

Supports per-VM as well as per-VMstore replication monitoring and topology views for reporting on data protection and disaster recovery service level compliance.

Key Capabilities of Tintri Automation Toolkit include:

· With traditional storage, end-to-end scripting in virtualized environments is complex, error-prone, and requires expert storage-admin level knowledge of various storage constructs, such as LUNs and volumes. With the Toolkit based on PowerShell, virtualization and cloud data management workflows can be automated with little to no knowledge of traditional storage constructs and commands.

“The release of the Tintri Automation Toolkit provides Tintri partners with a unique opportunity to add value with implementations of storage for virtualization and cloud,” said Jonathan Kowall, Principal Storage Architect of Sovereign Systems. “Customers want to add capabilities like self-service and policy-based automation. The fact that traditional storage is not scriptable at the VM level is often a major roadblock and breaks end-to-end automation. With the Toolkit, we can help our customers in their journey to private cloud.”

The Tintri OS 3.0 provides enterprises unparalleled density with the ability to run large scale virtualization and private cloud deployments with up to 2,000 VMs on a VMstore T650. Furthermore, enterprises can now deploy and manage up to 64,000 VMs spread across 32 geographically dispersed VMstore systems from a single Tintri Global Center 1.1 instance.

Re Post : Veeam Best Practices for VMware on Nutanix

by Roger Lund June 19, 2014

written by Roger Lund

Derek Seaman has a nice write up on Veeam Best Practices for VMware on Nutanix

I’m a fan of Veeam, and use in production today. Thus, I wanted to share the write up.

“The goal of the joint whitepaper between Veeam and Nutanix is to help customers deploy Veeam Backup & Replication v7 on Nutanix, when used with VMware vSphere 5.x. This post will highlight some of the major points and how customers can head off some potential issues. The whitepaper covers all the applicable technologies such as VMware’s VADP, CBT, and Microsoft VSS. It also includes and easy to follow checklist of all the recommendations.”

The official whitepaper can be downloaded here.

”
Veeam is modern data protection for virtual environments, and are also a great sponsor of my blog. The web-scale Nutanix solution and its data locality technology are complimented by the distributed and scale-out architecture of Veeam Backup & Replication v7. The combined Veeam and Nutanix solutions leverage the strengths of both products to provide network efficient backups to enable meeting recovery point objective (RPO) and recovery time objective (RTO) requirements.
The architecture is flexible enough to enable the use of either 100% virtualized Veeam components or a combination of virtual and physical components, depending on customer requirements and available hardware. You could also use existing dedicated backup appliances. In short, our joint solution is flexible enough to meet your requirements and efficiently use your physical assets. For example, if you have requirements for tape-out, then you will need at least one physical server in the mix to connect your library to since tape Fibre Channel/SAS pass-thru is not available in ESXi 5.x.

“When virtualizing solution the last thing you want is your backup data stored in the same location as the data you are trying to protect. So the first best practice for a 100% virtualized solution is to use a secondary Nutanix cluster. The cluster would be comprised of at least three Nutanix nodes. This is where the virtualized Veeam Backup & Replication server (along with the data repository), would reside. Should you have a problem with the production Nutanix cluster, your secondary cluster is unaffected. Depending on the amount of data you are backing up and your retention policies, you may or may not want the same Nutanix hardware models as your production cluster. For example, you may want to consider the 6000 series hardware which are ‘storage heavy’ for your secondary cluster. The following figure depicts a virtualized Veeam backup solution.”

Today I found my self looking for a way to add portgroups to a set of hosts in a cluster that have Standard switches.

I found Chris Nakagaki’s post http://tech.zsoldier.com/2013/07/add-portgroupsvlans-to-vmware-standard.html that covered this completely.

“Summary:
Wrote a simple little script to insert a portgroup into a targeted vSwitch of all VM hosts in a targeted cluster. This is not an issue if you use distributed vSwitches.

Script:
$vCenterName = Read-Host -Prompt “Please provide name of vCenter server”
$vCenter = Connect-VIServer $vCenterName

If ($? -ne $true){
Write-Host “$($vCenterName) appears to be invalid, please rerun script w/ correct vCenter name.”
Exit
}

$ClusterName = Read-Host -Prompt “Provide name of cluster you’d like to add a new portgroup to”
$Cluster = Get-Cluster $ClusterName

If ($? -ne $true){
Write-Host “$($ClusterName) appears to be invalid, please rerun script w/ correct cluster name.”
Exit
}

$VLAN = Read-Host -Prompt “Please provide VLAN ID: (0-4094 are valid values)”
$PGName = Read-Host -Prompt “Please provide name of port group: (i.e. 10.64.120.x)”
$vSwitchName = Read-Host -Prompt “Please provide vSwitch ID you’d like to add the portgroup to: (i.e. vSwitch2)”

$TargetHosts = $Cluster | Get-VMHost
Foreach ($VMHost in $TargetHosts)
{
$VMHost | Get-VirtualSwitch -Name $vSwitchName | New-VirtualPortGroup -Name $PGName -VLanId $VLAN
}

Disconnect-VIServer $vCenter -Confirm:$false

Infino : An VMware Cache Acceleration kit, in a Virtual box

by Roger Lund December 21, 2013

written by Roger Lund

This year at VMworld, I was able to attend the VMworld Tech Field Day Roundtable.

At the VMworld Tech Field Day Roundtable, I thought that Infino offered a great value add to those of us that have more than one hat in our job role. Today I am going to give you an insight to what the product is, how it gives you nearly instant results, and show you can how you see the value.

Infino is VMware acceleration in a box. Setup is as easy as downloading the application, agreeing to the license agreement and walking through the wizard.

Connect to vCenter
Choose Datastore
Verify Accelerator Resources

Setup Infino Management
Install Infinio Accelerator

Importing Management VM

Configuring IP settings
Synchronizing with vCenter
Deploying And Configuring Accelerator VMs

Install Complete

But wait, what did we just install? What is Infinio? It is a shared Memory Cache. All hosts share a single cache, deduplicated and stored once.

Here we have it, the dashboard shows your value.

First let’s dig into : Storage boost and Requests Offload.

Storage boost shows you the boot gained, and the number of disks it would take to provide the same boost.

Requests offloaded shows the number of requests that never had to go to disk, and the trend of those requests.

Wait I brought up deuplicated cache, whats does that mean? This should deduplicated workload’s with VM’s that have like memory set’s.

It shows you the Current, 1.3x Physical memory Cache size deuplication, with a 2x physical Memory 14-day peak.

Let’s not forget Datastore Response Time improved, Requests Offloaded, and Bandwidth Saved.

As you can see in the line graph’s, the product is providing I/O, therefore, lowing the latency, on the array.

My Impression of the product is this:

Infinio is all about providing a product, that you use, easily; without a knowledge expert, or a block of professional services from your var.

Need a use case?

If you are under the gun to provide performance in a environment that is growing, or it has increased demands. The product has the ability to be deployed fast, and without any hassle, and you get to see the results. Why is this important? A lot of IT Admin’s or System Admins have little time, and need to be able to be agile. I know, as I am a Admin in that role.

Thoughts and Comments? I plan on getting more time with Infinio in the future. Expect more to come!

I also wanted to share the Tech Field Day video coverage.

Solid Performance, with a Solid Name: Welcome to Solidfire.

by Roger Lund December 8, 2013

written by Roger Lund

I had the chance to meet with the CEO and Founder of SolidFire Dave Wright while at VMworld this year. Who is SolidFire? Well, I will overview that and share a interview I had with Dave shortly.

Solid fire is a all-SSD Architecture platform, that scales and uses raid-less data protection. But if you ask me, what set’s them apart on the SSD arena; I will answer with the QOS.

“Quality of service is not a feature. It is a architecture.” They go in to state it is ” the only way to deliver guaranteed storage performance in public and private cloud infrastructure” source
http://solidfire.com/technology/qos-benchmark-architecture/

The ability to set levels of service is critical in the service provider space. Min, Max and Burst IOPS per volume for example.

QOS Demo Video

As you can see below, the system can really push out the IO the numbers.

As you can see, fairly straight forward on the hardware side, however, I would recommend dedicated switching.

Source http://solidfire.com/technology/solidfire-storage-system/

What else? Add features like a array solutions, VMware , openstack, to name a couple and multitenancy reporting but I won’t touch on this today.

I’ll wrap up with a interview of me personally interviewing Dave, Owner and founder of SolidFire.

My Thoughts?

Need a top tier, with extreme performance? Need QOS? Need multitenancy? There are a Solid reasons to consider SolidFire when looking at Storage. Now if I could get a unit in my lab…

Thanks

Roger Lund

VMware and VMware Horizon View 5.3 the advent of View Composer API for Array Integration (VCAI) support in VMware Horizon View

by Roger Lund November 29, 2013

written by Roger Lund

VMware has released VMware Horizon View 5.3 : Read all about it: VMware® Horizon View™ 5.3 with a slew of new features and bug fixes. As always make sure you read the known issues.

“
There’s a treasure trove of value to be found here. We’re talking about things like full workstation class user experience with high-performance 3D graphics, enhanced abilities to access virtual desktops from any HTML5-capable web browser, a beautiful new iOS 7 client, as well as a completely rewritten Windows client with support for Windows 8.1. As if all of that weren’t enough already—we’re providing a brand new way to use Horizon View in Desktop-as-a-Service deployments using View Direct Connect. And one more thing: support for deploying Windows Server 2008 as a desktop.
”

Source http://blogs.vmware.com/euc/2013/10/read-all-about-it-vmware-horizon-view-5-3.html

On of the new features is that now no longer tech preview is View Composer API for Array Integration (VCAI) support in VMware Horizon View.

I’m pumped!

The following KB outlines this.

KB: 2061611

View Composer API for Array Integration (VCAI) support in VMware Horizon View (2061611)

“

1. Is View Composer API for Array Integration (VCAI) supported on Horizon View? If so, which release supports it?

Horizon View 5.1 introduced VCAI as a Tech Preview feature that enabled customers to try VCAI with partner storage systems that support VAAI NAS primitives. Horizon View 5.3 introduces support for VCAI with select partner storage technologies (listed in question 2 below). VCAI leverages capabilities of VMware vSphere as well as some of the NAS storage arrays that have vSphere API for Array Integration (VAAI) NAS native snapshot capability. This feature enables customers to offload the creation of linked clones to the storage array. It is used in conjunction with linked-clone desktop pools and NFS datastores that are exported by NAS storage arrays.

2. Which partner storage technologies support VCAI?

As of the Horizon View 5.3 release date, the following partner storage technologies support VCAI.

Vendor	Storage	Firmware*
Hitatchi Data Systems (HDS)	Hitatchi NAS 4000 Series	v11.x and later

*Vendors expect VCAI to work on these and later firmware versions.

3. What is the support model for VCAI on Horizon View?

The VCAI feature in Horizon View is supported only on specific storage arrays from certain vendors (listed in question 2 above). The VMware Global Support Services (GSS) organization provides joint customer support for this feature on those arrays only.

“

Therefore, unless you are running at Hitatchi NAS 4000 Series, put the breaks on! Althrough, I am sure we will see more storage support soon.

Here is the Hitatchi document.

Make sure to read through the entire press release at http://blogs.vmware.com/euc/2013/10/read-all-about-it-vmware-horizon-view-5-3.html and https://www.vmware.com/support/view53/doc/horizon-view-53-release-notes.html

Merge Multiple EMC NAR files with PowerShell

by Roger Lund September 18, 2013

written by Roger Lund

First off, I wanted to my apologizes for falling so behind on my blogging. I could make a list of reasons, both personal and work related , but I’ll not, and instead say sorry.

I plan on making some headway on the blog front, both here and at vbrainstorm.com Expect to see some new changes at vbrainstorm.com soon.

Now, on to the blog post!

I recently attended a EMC training class, titled VNX Unified Storage Performance Workshop, and we worked a lot of .nar files. As soon as I got back in the office, I found I wanted to combine .nar files to get a larger date range when looking at them.

I did a little Googleing and found this post.

Merge Multiple EMC NAR files with PowerShell

by David Muegge

I spend some time working with what code he had and came up with this.

$userinput = Read-Host “Enter case # or description:”
$Date = (Get-Date -format “MM-dd-yyyy”)
$TempFile = “E:emcnar_outTemp.nar”
New-Item E:emcnar_out$Date -type directory -Force
$OutputFile = “E:emcnar_out$Date” + “Merge – $userinput” + ” – $Date” + “.nar”
$NarFiles = Get-Childitem “E:emcnar_input”

$filecount = 0
foreach($NFile in $NarFiles){

    if($filecount -eq 0){Copy-Item $NFile.FullName $OutputFile}Else{

        Copy-Item $OutputFile $TempFile
        Remove-Item $OutputFile
        ./NaviSECCli.exe analyzer -archivemerge -data $TempFile $NFile.FullName -out $OutputFile

    }

    $filecount ++
}

It prompts you for the case# or a description of your choice. It will append this into the file name.
This outputs the files to E:emcnar_out with a sub-folder for the date. with a temp location of E:emcnar_outTemp.nar. The output file name come out like Merge – input – date .nar

Credit goes to David for the original script.

I hope someone gets some use from this.
