Increased maximum host mappings to 64K
Single copy volume expansion with format
iSER support for host attachment with 25 GbE adapters
Clustering support over Ethernet using RDMA
Support for Gemalto SafeNet KeySecure
Write throughput enhancements for San Volume Controller SV1 nodes, FlashSystem 9100 and Storwize V7000 Next Gen

▪ Initial fabrics
▪ Built on common NVMe architecture with
additional definitions to support message and
RDMA based NVMe operations over a range of
fabrics
▪ Fibre Channel – 8.2.1▪ RDMA-based transports such as
InfiniBand, RoCE, and iWARP - Future
Controller Side Transport Abstraction
Storage side NVMe Software▪ TCP was ratified recently - Future

Benefits of RDMA - iSER Host Attach and Clustering
Remote Direct Memory access (RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system
▪ Achieves Copy Avoidance
▪ Lowers Host CPU Utilization
▪ Offers Ultra-Low Latency

SVC (SAN Volume Controller) and Storwize products use 3 disks for quorum resolution (aka tie-break) and to store metadata that’s used for cluster recovery.
An area on mdisks is exclusively reserved for the 3 quorum disks.
In the 7.6.0, we first introduced IP quorum, where a quorum application can be used to tie-break a split-brain scenario, where half of the cluster can’t see the other half and the quorum app is used to break the tie.
Now this feature is about supporting the other half of the quorum functionality i.e., capability of storing data that’s used for cluster recovery.

Call Home
New Call Home Protocol – use sSMTP for the e-mail protocol with 8.2.1 and will automatically be used on
system upgrade
Cloud Call Home– Specifically designed to work with IBM Storage Insights and uses the RESTful-API to
transfer data directly to Storage Insights– Requires opening port 443 in the firewall for the following IP addresses:
• 129.42.54.189• 129.42.56.189• 129.42.60.189
– If cloud call home fails the system will revert to sSMPT– Notifications for clients and others will be sent via sSMPT

Multi-tenancy Object Based Access Control
RequirementSecurity and access enhancement through the use of Multi-tenancy. Provide the ability to server multiple tenants in a single storage system.
ValueMultitenancy Object Based Access Control gives the ability for each tenant to manage their allocated storage without knowing or caring about other tenants.
13
HyperSwap improvementsBackground:
HyperSwap redirects all read and write I/O to the primary volume copyThis adds one round-trip of extra latency to all I/O received at the secondary site
Reading from the local copy has long been a feature of stretched cluster and something that has been missing for HyperSwap systems, until now…
Solution:
Perform reads to the local volume copy, if it’s up-to-dateThis change is transparent to host systems, no configuration change requiredShould improve read response timesReduces the amount of traffic on the inter-site link

IP Quorum improvements
There are several independent improvements that have been made to
quorum.
These are known as:
1. Preferred Site for Tie-break
2. Winner Site
3. Reduced Lease Time
4. Host Health Check
