Really, as the name implies, use cases that are today homed on frame-based SAN, host-to-fabric topologies transition to VSAN using local devices...the serverfication of storage.
Agree. SMBs are moving back to 1-socket and many enterprises are moving back to 2-socket as their 'standard'. Always some use cases of course for super beefy servers.
Actually the economics of 2.5" SAS 10K - very popular - are not as good as 2.5" SSDs. The only area left for HDD is slow rotating. Even that will begin to subside given dense 3D NAND SSDs in the future.
at 2x reduction using Deduplication/Compression, along with Erasure Coding (RAID6/FTT=2), we're seeing a VSAN solution cost reduction of 28% (using list prices & no discounts) when using All-Flash vs. Hybrid.
Agree Jase - we are today at the point where all-flash has superior TCO to hybrid in nearly all cases. We see this all the time. Sounds nearly unbelievable, but the math is there.
@peglarr Breaking the $1 per GB barrier for usable storage is big. It changes people's perception that storage performance is worth managing on the primary storage layer.
@peglarr we expect RVC to be used only for our support and maybe for customers who really want to have that level of access. Otherwise everything will be in webclient and no need for command lines anymore
RVC is a fine tool, but I worry (for my customers) about security, authentication, etc. RVC is a very sharp knife. I suspect many companies will forbid its use unless in strict maintenance periods. Life in the big enterprise city.
@peglarr completely agreed. That is my expectation as well. That is the main reason we are exposing everything though webclient now. Also we are releasing SKD/APIs very soon as well
While the data reduction techniques are a great add, personally I like the ability to control QoS and give fine-grained control. Very valuable as you scale out.
The customers we talk to, since (full disclosure) we make very fast devices, are concerned that a given user will consume all or nearly all their 'horsepower'. QoS is a way to control that. Very useful in multi-tenant environments.
the other use case we had in mind was to ensure that the order of provisioning applications will not impact their performance. Without QoS the early VM/apps could take all the resources. QoS will add value here as well
Quite true. Adding QoS gives the environment a much greater ability to be 'fair' and allow all users to run/apps to execute according to business priorities
I'm particular to Sparse Swap files… I love the fact that I can choose to reserve this space or not. And it works on Hybrid and All-Flash architectures.
