How to – Deploy NetApp ONTAP Select 9.4

Following my last post on What is NetApp ONTAP Select and when to use it today I’d like to share some details on the actual deployment and how easy it is.
There are still quite some recommended hardware specifications and also supported configs but overall most of it should be present anyway on most datacenters, even the branch ones.

In this post I will show how to deploy just a single node configuration. The good thing is that the whole deployment will be handled by a wizard driven tool so there is no need to understand the basic ONTAP deployment like disk assigning, intitialization…etc.
Crazy what happened since I started working with Data ONTAP 6 on a FAS250 back in 2004 😉

What is NetApp ONTAP Select and when to use it

After a while I’m finally back with a new blog post. It’s been a crazy year so far with very little time to work on blogs. But now that the year comes to an end and the travel gets less I will share some posts with you on topics that I talked about most the last couple of months.

In this first post I’d like to talk a little bit about NetApp’s ONTAP Select solution as a lot of people don’t know yet that it even exists and what the use case might be. This post war written with ONTAP Select 9.4 GA data.

What is ONTAP Select?

If you look at NetApp’s website you will find the following description of what ONTAP Select is:
“NetApp® ONTAP® Select is a software-defined storage appliance that you can deploy on a variety of commodity hardware servers running the VMware ESXi and KVM hypervisors. ONTAP Select lets you quickly spin up storage resources in your data center, providing the agility you need to build a flexible and scalable private cloud infrastructure.”

How to: NetApp ONTAP reverse SnapMirror (CDOT)

I recently researched the ONTAP functionality to reverse a SnapMirror and as I didn’t found any useful blog post or even user guide explaining how to perform it on CLI I thought it’s worth to share on my own blog. In this post you will see two ONTAP systems where CDOT01 is the primary and CDOT02 is the secondary. My source volume here is called “datalunwindows” on the source SVM “SVMSRC” and my destination volume is named “SVMSRC_datalunwindows_mirror” on the destionation SVM “SVMDST”. Everything was tested with ONTAP 9.2.

What means reverse SnapMirror?
By that I mean changing the direction of the SnapMirror. The most likely best example is if you want to failback from a secondary ONTAP to the primary after a disaster.

Normal replication:
CDOT01/volumesource -> CDOT02/volumesdestination
Needed replication after a disaster:
CDOT02/volumesdestination -> CDOT01/volumesource

The change includes different steps an pre-requirements such as a broken SnapMirror relationship and that the source volume is still available and not completely lost. If you primary system is completeley lost you need to re-initialize to a new volume/system.

How do I perfrom a reverse SnapMirror?
The first and maybe easiest way would be to use the system manager as the latest version have the option to reverse a SnapMirror. But in my case I was looking for the way to do it on CLI as I was building some scripting around it.

1. Make sure your SnapMirror from CDOT01 to CDOT02 is broken and your data on CDOT02 is online.

##Check if mirror is broken
snapmirror show -destination-path SVMDST:SVMSRC_datalunwindows_mirror -fields state
##Check if volume is now in RW status (DP before)
volume show -volume SVMSRC_datalunwindows_mirror -fields type
##Check if volume is now online
volume show -volume SVMSRC_datalunwindows_mirror -fields status

2. Be aware that changing the direction will overwrite the current source data on the volume so don’t execute the commands without knowing what you do. To sucessfully execute a reverse, there needs to be at least one common Snapshot on the source and destionation volume which will be used as the baseline Snapshot. If there is no common Snapshot the command will fail.

3. Execute the resync command on the source ONTAP (CDOT01) to get data from the secondary. Yes you see right, the reverse is simply done by using the rescny command but on the source (new destionation) instead of the destionation (now source).

snapmirror resync -destination-path SVMSRC:datalunwindows -source-path SVMDST:SVMSRC_datalunwindows_mirror -force true

4. Check if the SnapMirror is now reversed. You should see that CDOT01 now has an active SnapMirror relation and CDOT02 is a source.

On CDOT01

snapmirror show

On CDOT02

snapmirror list-destinations

5. The reverse is already done now.
Optional: Ususally customers now want to make the source the primary now again and reverse the SnapMirror again to have the initial CDOT01->CDOT02 relation in place again. Therefore follow the steps below:

##Quiesce the relation on the source cluster (CDOT01)
snapmirror quiesce -destination-path SVMSRC:datalunwindows

##Break the snapmirror on the source cluster (CDOT01)
snapmirror break -destination-path SVMSRC:datalunwindows

##Mount the data back to your environment

##Resync the relation back from CDOT01 to CDOT02
snapmirror resync -destination-path SVMDST:SVMSRC_datalunwindows_mirror -source-path SVMSRC:datalunwindows -force true

##Cleanup the Snapmirror resync on source CDOT01
snapmirror delete -destination-path SVMSRC:datalunwindows

##Cleanup the Snapmirror resync on destination CDOT02
snapmirror release -destination-path SVMSRC:datalunwindows -force true

 

That’s it for this post. I hope it was useful for some of you. Feel free to comment or share on any channel.

See u next time.

How to: Upgrade NetApp ONTAP Simulator 9.1 to 9.2

For my tests and lab activities it’s always important to work with the latest version of software products. As the NetApp ONTAP simulator usually comes some times after the GA I decided to upgrade the simulator with the regular GA package and want to share here how to do it.

Before you start you need to:
– download the latest ONTAP 9.2 build
– make sure your root aggregate and root volume has enough free space
– disable snapshot scheduling and reserve on vol0 (yes, the vol0 on the node)
– The guide is for a single-node simulator

FlexPod goes SolidFire: FlexPod SF

Being at Cisco Live in Las Vegas last week I was glad that I had the chance to join the FlexPod SF launch happening on June 22nd. Unfortunately, I forgot to make some pictures but I want to tell you some details on the new FlexPod.

NTAP01651_SolidFire_Logo_Blk_MediumSF.jpg

According to IDC, FlexPod® is the #1 worldwide fastest growing integrated infrastructure and certified reference (source: IDC Worldwide Quarterly Converged Systems Tracker 2017 Q1) with a revenue growth rate of 26.1%. The other two vendors in the top three of market share saw their revenues decline. FlexPod SF is the first scale-out converged infrastructure solution in the industry, allowing customers to incrementally add storage as they consume it.

Since FlexPod was started in 2010 the validated Cisco + NetApp solution had great success and shows some amazing numbers:
2017-06-30 04_33_27-FlexPod_SF_Winnning Together June 15 PARTNER WEBCAST.pdf - Adobe Acrobat Reader .jpg

In 2015 NetApp then acquired SolidFire to grow their All-Flash Leadership and to offer a Scale-out storage system for the Next-Generation, Application-Centric data center.

And now, 2 years later FlexPod & SolidFire get together and the FlexPod SF is born.

2017-06-30 04_38_55-FlexPod SF partner deck_Final.pptx [Schreibgeschützt] - PowerPoint.jpg

The new FlexPod comes with Cisco UCS B-Series M4 Blades and Nexus 9k switching and contains the SF9608 storage nodes which can get up to 300000 IOPS in a 4-node cluster.
The design is fully validated and can be implemented like the regular FlexPod installations. 2017-06-30 04_41_56-FlexPod SF partner deck_Final.pptx [Schreibgeschützt] - PowerPoint.jpgLooking at the high-level design picture it is similar to what we already see and install since years so there won’t be a big need to learn everything from scratch again which is another plus point here.
The backend runs end-to-end iSCSI and depending on the B-Series Blade configuration you can run a 10G or 40G environment.
2017-06-30 04_45_43-FlexPod SF partner deck_Final.pptx [Schreibgeschützt] - PowerPoint
The SF9608 Node itself runs on Cisco UCS C220 M4 Hardware and comes with the following hardware:
– CPU: 2 x 2.6GHz CPU (E5-2640v3)
– Memory: 256 GB RAM
– 8 x 960GB SSD drives (non-SED)
– 7.6TB raw capacity (per node)
2017-06-30 04_51_42-FlexPod SF partner deck_Final.pptx [Schreibgeschützt] - PowerPoint
As mentioned before the solution runs iSCSI all the way and offers all benefits and features SolidFire had build-in. Esp. the QoS policies to define min. as well as max. performance for dedicated data streams is one of my favorite feature. It also helps to avoid “Noisy Neighbors” by setting limits for these workloads. Below you can find a performance chart before SolidFire QoS was enabled and after it was enabled:
QoS disabled:
Bild2QoS enabled:
Bild3

Overall I like the fact that the FlexPod Family is growing, not only in revenue but also with new family members. I’m looking forward to see the FlexPod SF in action (ok I saw it at Cisco Live already) and to talk to customers using it to get some feedback.
2017-06-30 04_53_14-FlexPod SF partner deck_Final.pptx [Schreibgeschützt] - PowerPoint.jpg

That’s me done for now, need to board the flight back home. I hope you like the post and look forward to see u again on my blog or receive your feedback.

 

NetApp goes HyperConverged-isch with NetApp HCI

On June 5th NetApp decided to disrupt the IT market and came out with several announcements around the Data Fabric, ONTAP 9 and finally their own HyperConverged solution. In this blogpost, I’d like to look a little bit deeper in how the HCI solution looks like and what we can expect when it is GA.
2017-06-14 20_11_26-Final Data Fabric Partner Webcast Slides-052617.pptx [Geschützte Ansicht] - Powe
According to IDC, the global HCI (hyper converged infrastructure) market is at $3 billion in annual revenue, and it’s expected to grow to $7 billion by 2020. NetApp HCI enables the customers to gain additional market opportunity and differentiation by selling an enterprise-scale hyper converged infrastructure into the most demanding data centers. Our IT market and industry is heading into the “Next Generation Data Center” and HCI is for sure one of the players in this area. To achieve consolidation and still maintain flexibility on the journey to the cloud customers need to look for new was on how to build their environments.

How-To ONTAP 9.1: root volume damaged

Recently I had two power outages on my lab. And after the second one my ONTAP 9.1 simulator came up with the error:
“root volume damaged”
“please contact NetApp support”
“The contents of the root volume may have changed and the local management
configuration … This node is not fully operational.
Contact support personnel …”

But as it is an simulator I tried to fix by myself. And after a while I found a solution that fixed it for me. If you see the same error the how to below can may help you out.

IMPORTANT: The following how to was used for a ONTAP 9.1 simulator in a NON-Production environment. No warranty and don’t use it in production clusters.
You are performing everything on your own risk so please always involve NetApp Support.

Veeam 9.5 and NetApp: Enterprise performance and scalability for NetApp storage with

Veeam just released version 9.5 of Veeam Backup & Replication. In this blog post, I would like to share some of the new capabilities that 9.5 delivers with our NetApp ONTAP storage integration.

As this is not a major version release, we didn’t add any specific new features, however, there are several improvements with respect towards backup resource scalability, which is of particular importance in enterprise data center environments.

1. Automatic NetApp LIF selection for data traffic

With 9.5, we implemented an advanced way for the Veeam backup server to identify the correct Data LIF for the backup process.
img01-1-700x427In the above example, the VM is stored on an aggregate located on Node 4. With 9.5, we made sure that data LIF4, of node 4, is used to access and backup the VM, instead of using data LIF1 on node 1 and transferring the data over the back-end cluster network. With this new implementation, we avoid the potential for node 1, or the back-end cluster network, to run out of resources during a Veeam backup.

The new cluster aware LIF selection also follows the data in case it is moved to another aggregate on another node, thereby ensuring the optimized path is utilized by the Veeam proxy server to perform data movement.

This functionality is enabled by default and does not require any action from your side to utilize this new capability.

2. Proxy affinity rules for storage access

The second enhancement is a new way to define proxy affinity between your NetApp ONTAP systems and the Veeam proxy server.
img02-1-700x204By using proxy affinity rules, you can easily define Veeam proxy server assignments for each NetApp ONTAP system. If there are multiple NetApp systems and Veeam proxy servers in the same environment, it is recommended to assign affinity relationships to avoid situations where a Veeam proxy server is misaligned with an ONTAP system. This capability saves time in the job initialization process and optimizes proxy resource utilization in larger environments, enabling you to ensure that specific proxy servers are available for specific backup jobs. img03-1-700x275This also ensures that local proxies are only accessing local NetApp ONTAP systems when using network based access protocols like NFS or iSCSI. img04To configure the proxy affinity, simply go to “Storage Infrastructure” within your Veeam Backup & Replication console and select the NetApp cluster you want to modify. Open the advanced settings and select the backup proxies Veeam should use.

3. Protocol selection to optimize proxy data access

One very common user request that we have addressed with 9.5 is the option to assign a different protocol to the Veeam proxy server than the one being used by the VMware server. Before 9.5, you could use different REG-Keys to force the Veeam proxy to use a different protocol. img05-1-700x466Now with 9.5, you can easily deploy a configuration where VMware is accessing the ONTAP cluster by FC, while the Veeam proxy uses iSCSI for backup and replication and all of the other Veeam features. Since the LUN is the same block device, it can be accessed via FC, iSCSI or both, enabling you to leverage your existing 10 GB network to back up the data via FC or iSCSI (or vice versa).

Besides the benefit of defining a different access protocol, you can also reduce the time that the Veeam proxy needs to scan and access your NetApp data and start a job, as the overhead required to check all available protocols is eliminated. In short, it’s a very simple way to optimize your existing Veeam and NetApp installation. img06To configure the protocol selection, simply go to “Storage Infrastructure” within your Veeam Backup & Replication console and select the NetApp cluster you want to modify. Open the advanced settings and select the protocol to be used by the Veeam proxy host. As shown in the above example, only the licensed ONTAP protocol is available to use.

In summary, the enterprise enhancements available in 9.5 make the Veeam integration with ONTAP more flexible and scalable. This is another great example of Veeam product development implementing feature enhancements based on the direct feedback from our customers and partners.

For additional Veeam and NetApp best practices, I highly recommend the following documents and articles:
