I took some rough/paraphrased notes during the talk, here's some terminology/highlights:
RDM:
Remote Direct Memory access, new tech at hardware level, leveraging on NIC and on network, faster access to storage with less overhead
SMI-S:
for storage vendor compatibility
NFS:
supposedly will be faster on Windows Server 2012 than on any other platform
Storage Spaces:
good, bad, weird, all about abstraction
renamed things like RAID, much like NetApp abstracts RAID from user
Reslient File System (ReFS)
limitations:
can't use for C: drive
deduplication doesn't work
for Hyper-V back end storage
Offloaded File Transfer (ODX)
need a storage array that is compliant with this, so transfer happens on storage array, rather than copy in and out of hosts
[to me, sounds like VAAI for VMware]
SMB Direct (RDMA)
specific NICs in client and server, less CPU needed on both sides, and transfer happens with mere nanosecond latencies
Thin Provisioning and Trim
can use VHDs and allocate only amount actually used up
TRIM let's you bring it back down if it bloats up
Data Deduplication
VHD library can see 90% savings, it's a post process (not inline)
