3. Me me me meeeee File Server and Cluster Team I get around
8 years in MS support
8 years IT shops and consulting
US Marine Infantry
The “Storage Replication PM”
DFSR, FRS (really!), and now… something new
AskDS and FileCab blogs

4. What is a disaster?

5. Sometimes you need more than a rack

6. Storage Replica is here

7. Storage Replica Replication Block-level, volume-based Flexibility
Synchronous & Asynchronous
SMB3 transport
Flexibility
Any Windows volume
Any fixed disk storage
Any storage fabric
Management
Failover Cluster Manager
Windows PowerShell
WMI
End to end MS Storage Stack

8. Demo
Proof that this is not vapor

9. Technical Preview Scenarios

10. What is block replication?

11. Blocks, not files This is not DFSR
Replicating storage blocks underneath the NTFS or ReFS volume
Don’t care if files are in use
Write IOs are all that matter to Storage Replica

12. Driver layering Monaco Site Source SR Server Nice Site
Destination SR Server
SMB Server
File System Filters
NTFS /
REFS
VolSnap Filter
BitLocker Filter
Volume Manager SR
Partition Manager
Disk Driver
Disk

15. Requirements & Recommendations

16. Especially MBR, from using Gen1 VMs!
Most “setup isn’t working” s I get are from not understanding these requirements
Requirements
Active Directory (for SMB)
No need for Schema updates, AD objects, certain AD functional levels, etc.
Uses Kerberos, not NTLM or certificates
≥1 Gbps network between servers
Disks
GPT, not MBR
Yes: JBOD, iSCSI, Local (non-cluster) SCSI or SATA, or SAN
No: USB external arrays, thumb drives, tapes, 5.25” floppy disks, etc.
Same disk geometry (see guide)
Free space for logs on a Windows NTFS/ReFS volume
No %systemroot% or page file
Firewall ports
SMB, WS-MAN
Especially MBR, from using Gen1 VMs!
JBOD: “Just a Bunch of Disks.” In Microsoftland, usually a serially-attached SCSI enclosure using Storage Spaces

17. Recommendations for Synchronous
Network latency
≤5ms round trip average
Assuming the light speed vacuum ideal, 5ms is ~1500km round trip
But reality steps in: optical fiber reduces by 35%, you cross switches, routers, firewalls, etc. – likely ≥2X latent at that range
Dark fiber and 10GBASE have logistical and financial limits
End result: most customers end up 30-50km (or stay within the campus)
Disk latency
Perfmon (logical disk) and DISKSPD
Use micro benchmarks before and after SR – not in Technical Preview, though! 
Log sizing and backing
SSD (if you want it to really work!)
Larger logs allow faster recovery from larger outages, but cost space
These are very strong recommendations ;)

18. Recommendations for Asynchronous
Network latency
Doesn’t matter
Disk latency
Same as previous slide
Log sizing and backing

19. Philosophy Async crash consistency versus application consistency
We guarantee a mountable volume
Your app guarantees a usable file
Snapshots
Whoops, this is broken in Technical Preview
Accept that async means possible data loss
We have no RPO dial in Technical Preview
How much money is your data worth?

20. Good ideas for anyone Drivers drivers drivers!
Filters filters filters!
Learn your performance envelopes

21. Your “other application” vendors must state support – we cannot.
What are the options? VM
SYSVOL
File Server
MS Exchange
SQL Server
Other Applications
Hyper-V Replica
Yes NA
Yes (VMs hosting file servers) No
Yes (VMs hosting SQL)
Yes (VMs hosting apps & servers)
Storage Replica
Yes No
Yes (bare metal or VMs)
Yes (VMs hosting SQL)
Yes (VMs hosting apps & servers)
SQL Server AlwaysOn FCIs NA
Yes
SQL Server AlwaysOn AG NA
Yes
MS Exchange DAG NA
Yes
DFS Replication No
Yes
FRS
Never
Upgrade to DFSR, soon
Don’t do it
Are you crazy?
What? No!
Hahaha, you are funny
Your “other application” vendors must state support – we cannot.

22. What Storage Replica is not
Storage Replica is not “shared nothing” clustering
Storage Replica is not a backup
We will happily replicate the deletion of all data!
Storage Replica is not DFSR
Not file-level
Not multi-master
Not multi-endpoint
Not low-bandwidth
Storage Replica is therefore not a general branch office solution
We mean it!

23. While we’re on the subject of offices and users…

26. Topology Stretch Cluster Server-to-server Cluster-to-cluster is coming
No 1-many
No a-b-c
No a-b-c-d
Cluster-to-cluster is coming
But not possible in Technical Preview
Fun fact: You can also create server-to-self
You are on your own, pal

27. Stretch Clusters

28. Stretch Clusters Synchronous only Asymmetric storage Manage with FCM
Two sites, two sets of shared storage
Cluster storage: CSV or role-assigned
Manage with FCM
Or Windows PowerShell
Increase cluster DR capabilities
Hyper-V and General Use File Server are the main use cases in the Technical Preview
Not Scale Out File Server

29. Familiar Failover Cluster Manager GUI

30. Configure and manage Add a source data disk to a role or CSV
Enable replication on that source data disk
Select a source log
Select a destination data disk
Select a destination log
Done. Really!
We’ve already changed this to 2,4,3,5 and altered nearly every word. 

31. Demo
Failover Cluster Manager Provisioning and Failover

32. Server to Server

33. Server to Server Synchronous or asynchronous
Any type of fixed disk storage (see previous rules)
Configure and manage with Windows PowerShell
Designed explicitly to increase the DR capabilities of a server
Cluster to cluster is coming
File Server is the main use cases in the Technical Preview
Ideally, no one ever uses this. Cluster to cluster is far more resilient.

34. Windows PowerShell Module: WVR Get-SRGroup Get-SRPartnership
New-SRGroup
New-SRPartnership (Create)
Remove-SRGroup

Set-SRGroup
Set-SRPartnership (change direction)
Suspend-SRGroup

40. Replication metadata Hidden disk partition Hidden logs
Always write through to disk
Registry (“real” and cluster hive)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WVR
HKEY_LOCAL_MACHINE\Cluster\WVR

41. Supportability Performance Counters Event Logs WPP Tracing
Dozens of useful counters
Made many improvements since Technical Preview
Event Logs
Hundreds of clear, guided, low-noise events
WPP Tracing
Booo! Requires calling MS.
If we do our events right, you will never need it

42. Known issues with Technical Preview
Removal of replication
PowerShell remoting
Performance
Finicky FCM
The ^%# name
The Step-By-Step guide covers all of this!

43. The big finish
