NetApp ONTAP 9.5 – Feature update

As NetApp Insight in the USA is in his last strokes NetApp has released a new feature update version of number one storage operations system NetApp ONTAP 9.5. In this release, there are some very interesting new features introduced

I have waited for a long time replication mechanism which provides zero data recovery with RPO equal zero and fast recovery with very low RTO build on SnapMirror. A new feature is called SnapMirror synchronous (SM-S). NetApp also used a new way of licensing with this highly useful feature. SnapMirror synchronous (SM-S) license must be purchased for primary cluster and is priced per size of volumes that are synchronously replicated. Traditional SnapMirror license must be purchased along. Currently, only most used protocols FC, iSCSI and NFSv3 are supported. Two modes of synchronous replication are available. A strict mode which should be used to replicate transaction logs from applications(Exchange, SQL) and normal mode used for usual data. For successful synchronous replication round-trip network latency must not exceed 10ms and number of synchronously-replicated volumes per-node limit must not be larger than 80 volumes for AFF and 40 volumes for FAS. SnapLock Compliance now supports SnapMirror XDP logical replication with storage efficiency mechanisms turn on.
Enhancements for Metrocluster over IP were also made with ONTAP 9.5. Support is now extended to up to 4 nodes of AFF A300 with ADP or FAS8200 without ADP. Supported distance is now extended up to 700km which is a really long distance.

New-old performance feature returned from 7-mode systems known as FlexCache. FlexCache feature in ONTAP 9.5 is located within clusters. Cache volumes are sparsely-populated within a cluster(intra-cluster) or across multiple clusters (inter-cluster). FlexCache volumes only cache only »hot« blocks of user data and metadata. Main benefits using flash cache are lower read latency at remote locations, increased collaboration, and productivity across multiple locations. Flex cache is used on NFSv3 volume and for typical use cases: ASIC electronic design automation (EDA) and media and computer-generated imagery (CGI) rendering.


NVMe Over Fiber Channel (NVMe/FC) multi-path fail-over with Asynchronous Namespace Access(ANA) is possible. ANA can be compared to ALUA in FCP world. ANA is another technology from NetApp which getting accepted as industry standard. ANA is for now supported only in SUSE Enterprise Linux 15.

FlexGroup can now scale up to 20PB and 400 billion files and supports additional SMB features like native file auditing, Fpolicy, Storage Level Access Guard, copy offload and inherited watches of changes notifications. FlexGroup volumes can span across multiple nodes or tier to the cloud.

With this release, NetApp has proven once again that they are following there Data Fabric strategy and they are making a highway for data to the clouds or between clouds. OnPremise systems are now even closer to clouds then they ever been.

vSphere 6.7 update 1 – what’s new?

vSphere 6.7 update 1 – what’s new?

Couple of days back new version of vSphere was released. Even if is just a minor update there a lot of new features and functionalities were released. The most important improvement was made on vSphere Client which is not the only client you will need to manage vCenter server. Finally, fully featured HTML5 vSphere client was released. You will never again need to switch to flash based client to run vSphere Update Manager (VUM) also many processes were simplified and will take you less time to configure. Users wishes were also fulfilled with dark theme. Multiple workflows were also removed and cut down to one workflow.

Couple of weeks back I needed to reconfigure vCenter with Embedded PSC to use new standalone PSC procedure to do that was complex and took some time to figured it up. vCenter Server Converge tool is a tool which helps you switch PSC configuration much easier and quicker. When I will upgrade this specific environment, I can also change configuration back to embedded PSC because from version vSphere 6.7 and even vSphere 6.5 U2 enhanced linked mode is supported. vCenter Server Converge tool can be used also to repoint vCenter Server with embedded PCS to another vSphere SSO Domain.

Security is one of top topic in IT industry, so all vendors tries to include security features into their solutions. VMware is no different. They introduced vSphere Platinum. New edition of vSphere delivers advanced security capabilities integrated into the hypervisor. VMware combined VMware AppDefense and vSphere with aim to bring secure applications to users. Beside VMware AppDefence VMware Platinum delivers FIPS 140-2 validated VM encryption and cross vCenter Encrypted vMotion, secure boot for ESXi and virtual machines, TPM 2.0 for ESXi and support for Microsoft virtualization-based security.

I am sure that anybody who manages VMware based virtual environment who already experienced problem when vCenter database was flooded with identical events over short period of time. Now with burst filter this will not be a problem anymore, because burst filter will block event bursts to flood database. New version of vCenter 6.7 update 1 also added screening for issues which proactively provides links to VMware KB articles and shortens solving time for issues.

For sure this update will go to history book of IT as last version of vCenter which is supported on Microsoft OS Windows Server and the first with fully featured vSphere Client.

NetApp Insight and why it’s the best conference in the IT industry

As summer is ending, the season of annual IT events has already started with VMworld World US in last month. There will be other IT following, however for me one of the best will always NetApp Insight. NetApp Insight is an annual event organized by data management company NetApp. The first time I’ve been to the event was in 2015. Over the past few years, the EMEA version of event has been held in Berlin. As usual, this year’s US event is held once again in Las Vegas, but the European edition will be this year in Barcelona, Spain in beginning of December. This is a welcome change of location for me. Not that Berlin wasn’t good, but going to conferences is great opportunity to do some quick sightseeing.

NetApp Insight 2014

And after three visits in Berlin, it already feels very familiar like home town to me, and the thrill of the unknown is already missing. As you can tell, I’m excited about Barcelona is to say the least. NetApp Insight has fascinated me by how well organized everything is, every session is carefully selected, so the participants are never bored and can always learn more useful information and acquire new knowledge. Each year there are more than 100 unique breakout sessions featuring NetApp solutions, case studies, best practices, tools and innovations.Of course, the NetApp technology mentioned a lot, but it’s done in a nice discreet way, so you don’t get the feeling you are being brainwashed, as I felt at so many events run by other technology vendors, where the organizers are very pushy and everything is all about them. NetApp Insight is well known among attendees as a very technical, not sales-oriented conference in contrast to other similar conferences. Sessions are built around NetApp product in combination with technologies from alliance partners such as VMware, Microsoft, Veaam, SAP, Oracle and others. You can hear and learn about other technologies aside from NetApp, which always comes in handy, when working on projects. Furthermore, NetApp Insight is also a great opportunity for improving and test your skills with Hands-on-Labs, free of charge NetApp Certification exams and technical training sessions. For me personally, the best feature of NetApp insight are the keynotes -with very interesting speakers like NetApp’s founder Dave Hitz (@DaveHitz) and Matt Watts (@mtjwatts), Director of Technology & Strategy.

I will never forget Dave Hitz’ story about comparing water pipes with data and how he came up with a new technology for NetApp customers to use less storage.

Dave Hitz looking to the future…

This feature is now known as deduplication and NetApp was the first company to introduce deduplication running on primary storage. Many people thought that Dave will sink the NetApp ship by providing deduplication for free to every NetApp customer and NetApp will end up selling less storage. They were wrong and NetApp was selling even more of storage and also other vendors followed the Dave Hitz idea…

In the next year’s keynote, Dave explained how he come up with the idea that NetApp needs to develop a way for customers to able to move their data seamlessly from their storage to cloud, like using plumbing pipes. The idea is now called Data Fabric. Data Fabric is now days widely used over the world as a highway for shipping data to clouds. Matt Watts had one year very interesting speech about how role of IT is changing. I find key notes like this very inspiring and they show you the vision of NetApp for the upcoming years. Most likely this year’s focus will be on cloud, as the cloud opportunity is rapidly growing. NetApp is focused on cloud innovations to create more cloud opportunities for accelerating new services. I believe modernizing IT architecture with cloud-connected flash will also be a major topic this year at Insight. Aside from the great content, one of the best benefits of attending Insight are the networking opportunities to connect with great people. I’ve enjoyed a lot the evening activities, which are always well organized, fun and overly great experience to remember. For example, I truly enjoyed the last year’s visit to the Berlin

Classic Remise depot, where classic cars and very expensive ones like Bugatti Veyron are displayed, as well as the appreciation parties at iconic venues such as the at Olympic stadium and the famous Tempelhof airport in Berlin. Last but not least, last year party was in an old Berlin underground station, was definitely one to remember, featuring an awesome cover band called RPJ, which was phenomenal and definitely rocked the party. I hope they bring them back once again in Barcelona. For me, personally the only downside to Insight is the conference pass price, which is a bit high. However, if you look at what the conference has to offer to you and your business it’s a great investment, especially considering the free certifications opportunity. I honestly promise you won’t be disappointed, just like one of my customers wasn’t when I took him to conference last year. Since then he’s been explaining how he thought it will be just another trip to Berlin, but he ended being amazed at the value of the conference and changed his mind completely. When we were on the way back from Berlin, he said that NetApp Insight is definitely a conference he will be coming back to next year.

I’m excited to be back to Insight this year in Barcelona and look forward to the keynotes and meeting with my fellow United members. I’m sure Petya Stefanova (@PeytStefanova), NetApp United coach will prepare something great for NetApp United members. Last year she organized a lot of activities (Pop-Up tech talks, hand football competition…) and I can not forget to mention a dinner with NetApp A-Team members and NetApp VPs, which was a very special start of NetApp Insight week.
