Hi everybody,
in reference to my prior article vSAN – High Available Solution this article will explain the basic architecture and give you some insight into the technical details.
Netapp Technology Forum Bavaria
Hello everbody,
last week on Thursday I attended a very nice event in the WWK – Arena in Augsburg. The host was Netapp and a lot of topics in form of presentations were covered. In addition I met a lot of sympathetic people.
I participated in various sessions and I listed the key facts of my favourites below:
Hardware and ONTAP 9.2
- 32Gbit Fibrechannel SAN
- 40 Gbit with 4x10Gbit break out connection
- Hotplug Storage Controller – adding more performance – live
- New ONTAP long term support release Modell -LTS (up to five years) and non LTS versions
- NVE – Netapp volume encryption
- Efficiency features
- Aggregate (former volume) inline deduplication
- Replication ( remote site needs more storage if inline data efficiency features are not supported )
- Data efficiency features performance impact <10%
- Opportunistic in nature – adaptive dedup
- Fabric pool -> Capacity Tier -> Public or private cloud
- QoS features in SAN
- Min – max throughput per LUN
- IOPs per LUN
- Just in SAN
DevOps and Container
- Concepts of app operation and software development
- Standardize – consolidate – virtualize – automate – orchestrate
- Digital innovation and transformation
- DevOps:
- Plan -> Develop -> Release -> Monitor -> Repeat
- OSIMM
- Non dynamic historic concepts replaced
- For example: Apple release cycle – just a small part of users impacted
- API SDK REST – Integration of common tools
- Software defined infrastructure – environmental snapshots
- DevOps as process of operation and development of infrastructures
- New Job holders like “Site reliability engineer” (Google)
- >50% Infrastructure
- Predominant app developer
- Container – differences to the traditional way (monolithic applications)
- Micro services
- Meshed over REST
- IP based
- Sufficient performance available nowadays
- Can be upgraded independent
- Concept of load balancing a.k.a horizontal scaling
- For example: Google search engine
- Containers are not virtual machines
- Data storage out of the container
- Container orchestration:
- Kubernetes ‘k8s’
- Dockerswarm
- Mesos
- Dynamic vs. persistent provisioning
GDPR – General data protection Regulation
- GDPR called EU-DSGVO in Germany
- Replaces the German “Datenschutzgesetz”
- Affects every company which handles European personalised data or does Business with European companies
- Will come into force on 25.05.2018
- Save Harbour -> Privacy Shield -> GDPR
- Company’s need additional personnel which are responsible – data protection Officer – privacy officer
- Punishment for data leakage: up to 4% of yearly revenues or 20 million euros
- Authorities must be informed within 72h
- Everybody has the right to be forgotten
- Data lineage
- Physical location of the data must be documented
- Data migration must be possible from one to another provider ( standardized file format, machine readable)
- Concept of pseudonymization will be important
- Encrypted data breach may not necessarily be reported to authorities
- Code of conduct and certifications
- Usage of hardening guides
