Hyper-V Amigos Showcast – Episode 18 – Hyper-V 2019 and Persistent Memory

Join the Hyper-V amigos who test Persistent Memory (PMEM in the lab a bit).PMEM is solid-state high-performance byte-addressable memory device that resides on the memory bus. If you have not heard of or read up on PMEM it is really time you do.

Let’s find out what it is and where it fits in. PMEM is dominating the buzz on the storage and memory scene at the moment, it is “hot”. Rightly so, PMEM is changing how the IT world thinks about and consumes storage. Not wholesale overnight but it will be a game changer.

The nature of PMEM improves the way applications use CPU cycles, how data is retrieved and persisted as well as how memory is consumed. This means significant changes in the hardware and software stack are needed to leverage these capabilities. An era of very fast, high capacity, low latency storage class memory with high endurance is coming.

We hope you enjoy the Episode.

Hyper-V Amigos Showcast Episode 12–ReFS and Backup

In this Episode Didier and I look at a single host deployment with Storage Spaces on Windows Server 2016. We create a “Hybrid” disk just like in Storage Spaces Direct by combining SSD & HDD in a storage Tier. We were very happy to discover that ReFSv3.1 does real time tiering. We’re very excited about this because we want to leverage the benefits if Veeam Backup & Replication 9.5 brings by leveraging ReFSv3.1 (Block Cloning) in regards to backup transformation actions and Grandfather-Father-Son (GFS) spaces savings. To do so we’re looking at our options to get these benefits and capabilities leveraging affordable yet performant storage for our backup targets. S2D is one such option but might be cost prohibitive or overkill in certain environments.

ReFS v3.1 on non-clustered Windows Server 2016 hosts bring us integrity streaming, file corruption repair with instant recovery as protection against bit rot, the performance of tiered storage and SMB3 as a backup target at a great price point.

But please watch the video and see for yourself.
