Speicher und NetzwerkSoftware Defined Storage & Software Defined Networking

• Hot-Add: Speicher und Netzwerkkarten im laufenden Betrieb zu tauschen

• Network Controller-Rolle– Zentrale Sicht auf alle physischen und virtuellen Netzwerkkomponenten

• Storage-Policies QoS Quality of Service (Neu)– Richtlinien, um z.B. festzulegen, mit welcher Geschwindigkeit auf eine VM oder virtuelle Festplatte zugegriffen werden

kann.

– Steuern der minimalen und maximalen Bandbreite der einzelnen Server beim Zugriff auf den Speicher

• Storage Spaces Direct (Verbessert)– Speicher zu einem virtuellen Pool (Storage Pooling) zusammenfassen und besser im Netzwerk verteilen. Jetzt auch auf

verschiedene Server.

– Erlaubt Hyper-converged Storage (Compute und Storage gemeinsam) und Converged Storage (Compute und Storage separat)

– Software Defined Storage: für Private Cloud durch Industrie-Standard Servers mit lokalem Storage

• Storage Replica– Ein für die Notfallwiederherstellung-relevantes Storage-Feature, um Daten synchron zu halten.

Wahl zwischen Shared SAS und DAS

• Deployment modes1. Remote data access using Scale-Out File Server

2. Hyper-Converged

• File System (CSVFS with ReFS)• ReFS is the primary file system

• Cluster-wide file system

• Fast VHDX creation, expansion and checkpoints

• Storage Spaces• Scalable pool with all disk devices

• Resilient virtual disk

• Software Storage Bus• Spans entire cluster

• Leverages SMB3 and SMB Direct

• Servers with local disks• SATA, NVMe, SAS

Storage Replica (SR)

• Synchrone Replikation für die Datenspiegelung mit ausfallresistenten Volumes (Zero Data Loss)

– zwischen einzelnen Servern eines Standorts

– für einen Failover-Cluster auf mehrere Standorte (Stretching)

• Asynchrone Replikation bei hohen Distanzen/Latenzen mit der Möglichkeit des Datenverlusts

– Server zu Server standortübergreifend

– Cluster zu Cluster

• Kein Ersatz für Hyper-V Replica & kein Ersatz für Backup

Storage Replica - asynchron

• Network latency• ≤5ms round trip average

• Assuming the light speed vacuum ideal, 5ms is ~1500km round trip

• Reality: optical fiber reduces by ~35%, you cross switches, routers, firewalls, etc.

• Financial limits, availability

• End result: most customers end up 30-50km

• Network Bandwidth• ≥1 Gbps network - end to end - between servers is a starting point (Windows Server

logo requires 1Gb NIC)

• It depends on your IO and sharing of the pipe (SR may not be the only traffic for the DR site)

• Learn your IOPS math (125MB/s of IO = ~1Gb/s network usage)

• Log volume performance and size• Flash (SSD, NVME, etc.)

• Larger logs allow faster recovery from larger outages and less rollover, but cost space

Recommendations for Synchronous

• Network latency

•Doesn’t matter

• Network bandwidth

•As much or as little as you need

•Depends on your write IO

• Log volume performance and size

• Same as previous slide

Recommendations for Asynchronous

• Network Controller

• Hyper-V Virtual Switch

• Network Function Virtualization (NFV)

• Software Load Balancer (SLB)

• Network Address Translation (NAT)

• Datacenter Firewall

• RAS Gateway

• Standardisierte Protokolle

• Flexible Techniken zur Netzwerk Kapselung

• Converged Network Interface Card (NIC)

• Packet Direct

• Switch Embedded Teaming (SET)

• Network Monitoring
