All new Data ONTAP9

Written by Mo Elamin. Posted in Blog, Storage

The new version on Data ONTAP is now out in the wild, now called ONTAP 9. Not clustered data ONTAP nor data ONTAP 7-mode. From now on, it will just be ONTAP, since 7-mode is no longer being developed. RC1 is scheduled to be out by late June, 2016. Over The last few years, NetApp has focused on bringing feature parity to cdot, so new features and usability were a little behind. However, the company is now at a point of greater innovation and most importantly, they are finally listening to their partners, and customers. ONTAP 9 brings great enhancements to the already well known features such as DataMotion, Compression, and dedup among others. It also includes features such as data compaction, HeadRoom, and RAID-TEC among others. The main noticeable change on ONTAP 9 is a major face lift. Yes, the GUI is different; way different, while keeping some of the old look. In my opinion, it makes a lot more sense to control everything at a higher level, rather than having to hunt drop-down menus at different locations, just like the 8.2 days. The new UI brings simplicity and usability at the same time, with an intuitive, non-cluttered set of tabs. Below are some screen shots of the dashboard of ONTAP 9 UI. The main menu is composed of 7 tabs that will give you access to manage and configure your NetApp cluster. Categories include Dashboards, LUNs, SVMs, Network, Hardware and Diagnostics, Protection, and Configurations. ontap_9

NetApp Performance Monitoring with Graphite, and Grafana

Written by Mo Elamin. Posted in Blog, Storage

I have not had a chance to write many articles recently, mainly because I have been heavily involved in building a very large dual site Netapp clustered ONTAP FAS8080 deployment.

As part of the project we installed graphite to do some of the quantitative monitoring of the clusters. This helps to view performance and capacity information about our NetApp systems in the open source metric platform Graphite and Grafana.

Graph

Graphite is an open source enterprise-scale monitoring tool that does two things:

  • Store numeric time-series data
  • Render graphs or API responses of this data on demand
 

Graphite itself has no metrics collection engine but rather receives metrics sent to it. Graphite supports various techniques to scale up and out the three main components and is quite powerful. Metrics can be retained by Graphite for a configurable retention period and frequency. The Graphite webapp also supports dozens of functions that allow for easy manipulation of collected data into useful information.

Grafana is an open source feature rich metrics dashboard and graph editor for Graphite. It provides a powerful and elegant way to create and share your own dashboards. It supports a wide variety of graphing options forultimate flexibility.

Grafana supports authenticated login and a basic role based access control implementation. Grafana is deployed as a single software installation and includes a webserver and presentation logic and is written in Go and JavaScript.

Graphite is installed using a Virtual appliance. Here is a video demo of Graphite virtual appliance Install  

                 

Latest 7-Mode Transition Tool 2.0

Written by Mo Elamin. Posted in Blog, Storage

7MTT

Really surprised at how quickly Netapp are developing their migration tool for moving from 7mode to cluster ONTAP. It was only just a few months ago that we had version 1.4.

Currently I am in a similar situation in my current job, where it’s that time move. I think any customer who already has Netapp controllers, familiar with Data ONTAP and netapp features has only on route, to transition to Clustered ONTAP.

The 7MTT minimizes the time that your data is offline by initially doing a baseline SnapMirror transfer. When the baseline is complete the tool starts performing incremental updates based on the timetable you set. During this time, the primary 7-Mode volume is online and continues to serve data as normal. Incremental updates continue until you decide to cut over, which is the only time when clients see an outage.

The amount of time needed to cut over depends on the time needed to finish an incremental update. Three to four minutes is typical to complete the final incremental update. Once the final incremental update occurs, you need to manually disconnect your clients from the volumes you are moving before cutting over. Then redirect your clients or restart application services to use the volumes in the new location.

The new release of the 7MTT 2.0 RC1 allows you to transition to clustered Data ONTAP 8.3. 32-bit data is not supported on in clustered Data ONTAP 8.3, so you must expand the 32-bit aggrates to 64-bit.

SAN transition to clustered ONTAP is now supported, this is a long awaited feature, most customer have a large number of Luns within their controllers so this is welcomed feature. Finally MetroCluster support, this will enable you to transition an already configured MetroCluster in clustered ONTAP 8.3.

You can download Windows or Linux versions of the 7MTT 2.0 from the NetApp Support Site.
