VMAX software enhancements
• FICON Performance improvements
• FLASHBOOST for CKD– Implements Optimized Read Miss in the FICON emulation (EF) to significantly improve throughput and
lower latency for Random Read Miss (RRM) workloads directed at flash drives
• zDP Enhancements – Monitor the RDP cache usage and issue messages and take user specified actions when thresholds
are reached– Provide SMF records for data in zDP query commands, including RDP space consumption information– Provide an option to Terminate Snapsets
• Secure Snaps– Customers who need to protect their snapshot data from deletion or data corruption (intentional or
unintentional) – Supports an Isolated Recovery Solution
© Copyright 2017 Dell Inc.27
Software enhancement details
• Newest Features in Mainframe Enablers (MFE) 8.2– Secure Snapshots– TimeFinder SnapVX
• What is new with the latest Hypermax– Data Protector for z Systems (zDP) Enhancements– SMF Enhancements– EAV– Dynamic Volume Expansion

Secure snapshots
Overview
• Prevents a snapshot from being deleted by anyone– Think of it as a “Time-To-Must-Live”
• Why provide this feature? – Intentional or unintentional data loss
• Requires supported versions of HYPERMAX OS / SE /UVMAX / MFE
• Supported for both FBA and CKD devices
• Only applies to native SnapVX targetless snapshots– Not applicable to SnapVX Linked Targets– Not applicable to Emulation modes (Clone, Mirror, VP Snap)
© Copyright 2017 Dell Inc.30
Secure snapshots
Overview
• Care must be taken when implementing this feature!
• No user will be allowed to reduce or remove the Retention Time
• Secure Snapshots cannot be terminated to free-up SRP capacity
• Users may want to consider how to implement– Specific points-in-time– Specific number per day– etc...
• All other SnapVX operations are allowed:– Link / Relink / Unlink– Restore / Terminate restored– Set mode
© Copyright 2017 Dell Inc.31
Secure snapshots
Overview
• Retention Time can be extended but not reduced
• Standard Snapshot can be converted to Secure Snapshot– Not vice versa
• When the Retention Time expires:– If the snapshot has no linked targets or restore sessions it will be automatically terminated– If the snapshot has linked targets it will be automatically terminated when the targets are
unlinked– If the snapshot has a restore session it will be automatically terminated when the restore
session is terminated

Extended Addressable Volume (EAV) background
• EAV restrictions due to host operating system
• Prior to this release, supported EAV up to 262,668 cylinders
• At GA, supported EAV totaling ~1TB or 1,182,006 cylinders
• Use DVE to expand volume
• EAV volumes supported on z/VM 6.3 and higher
• EAV Volumes supported on z/OS 1.13 and higher
• EAV volumes NOT supported for z/TPF
• Volumes over 65,520 cylinders will be labeled as 3390-A
© Copyright 2017 Dell Inc.58
Understanding Dynamic Volume Expansion
Overview
• What does DVE do?
• Devices targeted for expansion can remain online
• Once increased, cannot reduce the size – Devices can be expanded multiple times
• At initial release, all Dell EMC and IBM copy operations to that volume must be stopped before expansion can take place
• Use case: As customers reach host device addressing limits, the ability to increase existing devices was needed
Before
After
© Copyright 2017 Dell Inc.59
DVE specifics
• DVE allows for 3390 CKD devices to be expanded
• Max cylinder size for expansion = 1,181,006 (A LOT) = ~1TB
• Expanding a device up to 65,520 will be done in one cylinder increments
• Expanding a device up from 65,521 – 1,181,006 will be done in increments of 1113 cylinders
• The model for an expanded device will be –A– Therefore 3390-3 expanded with a 10017 (which is a mod-9) will be displayed as a 3390-A
