Storage Infrastructure and Protocols

In immortal words of Howard Marks, "Storage is different". In this section you'll figure out why storage administrators have to have a totally different view of the world, how traditional storage was implement, what software-defined storage and hyperconverged infrastructure are, and what protocols you might have to support to connect physical or virtual servers with the storage arrays or scale-out storage infrastructure.

2:39:09 All You Need to Know about Storage

Howard Marks, a renowned storage guru, started his presentation with a brief introduction of traditional storage technology including:

  • performance metrics,
  • storage systems,
  • RAID data redundancy,
  • storage protocols.

The core of his presentation focused on modern storage concepts including object storage, software-defined storage, scale-out architectures, erasure coding, the impact of flash storage, and hyperconverged infrastructure.

He concluded with a plethora of interesting topics we rarely hear about in enough details including snapshots, storage QoS, per-VM storage services and VMware vVols, and various storage replication mechanisms.

52:46 Storage Protocols

After mastering the storage basics, it's time to discuss the storage protocols. This section describes:

  • Typical storage access methods
  • LUN-based and file-based storage solutions
  • Fibre Channel and Fibre Channel over Ethernet (FCoE)
  • iSCSI and NFS
  • Lossless Ethernet transport and Data Center Bridging (DCB)

29:37 Designing Compute and Storage

By now you should have a pretty good understanding of compute and storage infrastructure. Let's see how we can use that to do the compute and storage parts of a data center design.

18:08 Compute and Storage Infrastructure Discussion - 2017

The discussion part of "compute & storage" module focused on hyperconverged infrastructure.

Design Assignment: Design a Storage Solution

As the last step in this module you'll design a simple storage solution. If you're not familiar with the basics of data center fabrics you might want to skip this exercise and do it after going through the data center fabrics part of the course.
