© Copyright IBM Corporation 2021
3 Site HyperSwap Overview
• Active – Active Relationship capability with ability to asynchronously copy data to DR (Auxiliary Far)
site
• Zero RTO / RPO across HyperSwap sites and minimum RPO of 10 min on far site (5 minutes cycle
time)
• Automatic coordinated replication to DR (Auxiliary Far) site using external Orchestrator.
• Ability to convert existing HyperSwap configuration to 3-site configuration
• Stateless and Fault Tolerant Orchestrator architecture for managing 3 site replication.
• Protocol agnostic architecture – Can use FC OR IP for all or part of the solution
• Limits for HyperSwap(1250 vols (8.3.1) -> 2000 vols (8.4)) and as per standard GMCV
implementations
10
© Copyright IBM Corporation 20213 Site HyperSwap Terminology
• 3 site consistency group states:
• 3 site consistent : A consistent copy is available on far site
• 3 site inconsistent : Far site does not have consistent image
• 2 site periodic: Indicates one of near site is not part of 3 site replication
• Stopped: Indicates data cycle is stopped
• Partial: Indicates that all relationship in consistency group are not converted to 3 site
11
© Copyright IBM Corporation 20213 Site HyperSwap Use Cases
• Regulatory Compliance
• Need to maintain 3+ copies of production data
• High Availability during Disaster (Site Failures)
• Ensuring availability of minimum 2 copies of data at all times
• High Availability during Maintenance
• Ensuring availability of minimum 2 copies of data during maintenance
• High Availability during Link Failure
• Ensuring availability of minimum 2 copies of data during link failures
• Site Migration
• HyperSwap Cluster migration from one location to another using FAR site
• Load Balancing
• Load balancing between sites for periodic replication source
12
© Copyright IBM Corporation 2021DRP Updates © Copyright IBM Corporation 2021
• Uses DRP’s internal deduplication
Redirect-on-write for DRP snapshots referencing capabilities to reduce
overheads by creating references instead of
copying the data
• Adds a redirect-on-write (RoW) alternative
to the existing copy-on-write (CoW)
capabilities
• Also known as Flash Optimized Snapshots (FOS) • Source and Target MUST:
• Be deduplicated
• Reduced backend I/O amplification for
snapshots • Reside in the same DRP pool
• Reside in the same I/O Group
• Better deduplication ratio for snapshots • Volume cannot be mirrored (VDisk mirroring)
• Automatic mode selection (RoW/CoW) based on the
conditions above (Note: no way to verify)

© Copyright IBM Corporation 2021Child Pools in a Data Reduction Pool
• New pool type, child_quotaless
• Child pools in a standard pool continue to function the same
• Child pool consumes parent’s free capacity as volumes are created
• No way to set quota
• Child pool shares parent pool’s encryption key
• In a standard pool, for externally encrypted storage, the keys for child and parent could be different
• Cannot set a separate space warning level. Warning alert is at parent level
• Child Pools allow Object Based Access Control to be used with a DRP
• vVols are not supported yet
• Same rules for volume creation as parent DRPs (data reduction, fully allocated, compressed,
deduplicated volumes)
• Child and parent DRPs share data disks
• Garbage collection works across parent and child pools
16
© Copyright IBM Corporation 2021Migration within a DRP (migratevdisk)
• All volumes can be migrated between parent and child DRPs, and between child DRPs
• Volumes can only be migrated from a child DRP to and from its parent, or child pools in the same
parent
• addvdiskcopy can be used to get between DRP pools
• Volumes can be migrated between encrypted data reduction parent and child pools, as they share an
encryption key.
Note: Volume copy (VDisk mirroring) can be used for other types of data movement 17
© Copyright IBM Corporation 2021Distributed RAID 1 (DRAID1) © Copyright IBM Corporation 2021
What Is DRAID-1?
• DRAID-1 is a distributed mirrored based RAID configuration
– Logical mirror and rebuild area distributed over all member drives
• Supports all DRAID-5 and 6 features
• Minimum 2 drive configuration and maximum of 16 drives
– Not available for FCM-XL (38.4TB) modules
19
© Copyright IBM Corporation 2021DRAID1 - Purpose
• Extremely high I/O performance
• All drives participate in I/O
• Optimized I/O path for multi-core CPUs
• Extremely fast rebuild on small arrays to a distributed rebuild area
• All drives participate in rebuild
• High performance solution for small SCM/flash arrays
• Entry point for FCM based FlashSystem
• 2 large (19.2TB) FCM2/FCM2.1 drives or 2 SCM drives
20
© Copyright IBM Corporation 2021DRAID1 – Configuration Considerations
• 2 member drives per array (0 rebuild area)
• SSDs - including SAS flash drives, NVMe flash drives, NVMe FCMs
• SCMs - up to 8 TB for each member drive
• 3 - 16 member drives per array (1 rebuild area)
• Same as 2 member drive arrays
• HDDs (spinning disks) - up to 8 TB for each member drive
• System recommendation is to create DRAID-1 in arrays up to 6 drives
• GUI will allow creation only up to 6 drives
• Can go to the max from the CLI
• Minimum extent size: 1024 MB
• Note: This is the first DRAID type with a minimum extent size
• Stripe width (width of a single unit of redundancy) – 2
• Strip size: 256 KB Only
21
© Copyright IBM Corporation 2021DRAID-1 Configuration - Rebuild
• Rebuild operation starts when one of the array
drives fails and the rebuild area is available
– If rebuild area is not available, array state will
change to degraded
• All array drives participate in the rebuild
– No bottlenecks
Note: Diagram is logical only. Rebuild area spread across all drives
22
© Copyright IBM Corporation 2021DRAID-1 Configuration – Rebuild-in-Place (a new capability)
• DRAID-1 is the only distributed array that can be configured without a rebuild area.
– Minimum configuration of two drives
• When a drive is failed and replaced, the rebuild-in-place process starts to mirror the
data.
– Multithreaded operation (faster compared to TRAID)
23

• Problem • Solution
• This situation occurs in a DRAID5/6 array when • Rebuild in Place – Introduced with the release

This significantly slows down the copyback • The copyback will be continued in a non-degraded
• Little or no redundancy and even if the failed drive mode
is replaced a spare out cannot occur until the
copyback in process finishes.
24

30
© Copyright IBM Corporation 2021 Note: The write performance bottleneck now becomes the drivesDRAID Rebuild Rates
• FCMs
• DRAID1/5/6 – Rebuild target is 5.1 TB/hr
• Industry Standard NVMe Drives
• DRAID1/5/6 – Rebuild target is 2.5 TB/hr for one rebuild area, 5 TB for 2 concurrent rebuilds
Note: More parameters are included in the equation to calculate the rebuild rate and in some cases,
depending on stripe width, the rebuild rate for an array with FCM/NVME members can be set to 3.7 31
© Copyright IBM Corporation 2021
TB/hr128 KB Strip Size Removal
• Removes the ability to create new DRAID (1/5/6) arrays with 128 KB strip size
• CCU for arrays with 128 KB strip size is supported
• T4 recovery for arrays with 128 KB strip size is supported
• DRAID-1 with 128 KB strip size is not supported at all
• Removed from both GUI and CLI
• Reasons are:
• Little benefit of 128 KB strip size in today's operating environment
• Part of the "Do No Harm" drive, reduces configuration complexity in field
32
© Copyright IBM Corporation 2021© Copyright IBM Corporation 2021
• Choice of local or remote authentication (or use
Prior to 8.4 both)
• The remote authentication admin can set
password and account policies, and
authentication policies
• No policy options for local accounts.
• Minimum password length always 6
• The only customisable option was the session timeout
when using GUI
34
© Copyright IBM Corporation 2021• For local accounts
Clients want … • To set their own password policy e.g. 15 characters
minimum, must include 1 number and 1 special
character.
• More control over account locking.
• IBM to meet competitive/existing password policy
options
• A way to disable the superuser account (and use
LDAP authentication only).
35
© Copyright IBM Corporation 2021• A new set of options to allow a security admin to
What IBM is Delivering for Local Accounts create policies for passwords, account lockout,
session timeout.
• Create a single system-wide policy that applies to
all local accounts (session timeouts also apply to
remote accounts).
36
© Copyright IBM Corporation 2021• Customizable
Local Password Creation Options • Minimum password length (6 – 64 characters)
• Minimum number of upper-case characters (1 – 3)
• Minimum number of lower-case characters (1 – 3)
• Minimum number of special characters (1 – 3)
• Minimum number of digits (1 – 3)
• A new policy does not apply retroactively to existing
passwords
• However all passwords can be invalidated forcing users to
change their passwords
• Any new passwords must meet the current policy
setting.
37
© Copyright IBM Corporation 2021• Password History checking can be enabled.
Password Creation Rules • 0 – 10 previous passwords can be checked.
• Stores the previous password hashes only (i.e.
no plaintext).
• 0 = compare the current password only.
• 10 = check that the new password does not
match the current password or the 10
passwords used prior to the current password.
• The minimum required password age can be set
(0 – 365 days). A minimum age of 1 means that
a user can only change password once per day.
(which prevents a user from cycling through the
history.)
• The history is not checked when a security
admin changes another user’s password.
• Not supported on FlashSystem 5010(E).
• Memory constraints
38
© Copyright IBM Corporation 2021• Passwords can be set to expire after 0 – 365
Password Expiry days.
• All existing passwords will be set to expire in X
days when the setting is first enabled.
• A user with an expired password can log into
the system, but will have monitor privilege only
• When they change the password the previous
privileges will be restored
• An expiry warning can be enabled (0 – 30 days)
which will warn the user on login that their
password will expire in X days. (Only on the CLI
in 8.4)
39
© Copyright IBM Corporation 2021• The security admin can force a user to change
their password at any time. The password will
Requiring Password Change expire immediately. (CLI – individual users, GUI
– button to reset all user password)
• Can be used when creating a new user to require a
password change on first login.
• Can be used after changing password policy
settings.
40
© Copyright IBM Corporation 2021Manual Account Locking - CLI Only
• The security admin can manually lock and unlock user accounts:
• svctask chuser -lock bill
• svctask chuser -unlock ted
• A locked account is not allowed to log in to the system.
41
© Copyright IBM Corporation 2021• Set the maximum number of failed login
Automatic Account Locking attempts (0 – 10)
• The counter is reset on a successful login
• Set the length of time a user will be locked out
of the system (0 – 10080 minutes (which is 7
days), 0 = indefinite)
42
© Copyright IBM Corporation 2021• Feature available on platforms with a dedicated
techport (i.e. not FlashSystem 5010(E), 5030(E)
Disabling Superuser or Spectrum Virtualize for Public Cloud).
• Explicit option to enable superuser locking
• svctask chsecurity -superuserlocking enable
• svctask chuser -lock superuser
• Use case: Some enterprises have policies that all
systems should use remote auth.
• Configure remote auth, create a remote security
admin, disable superuser (now no local accounts
can log in to the system).
• The superuser account is still required for satask
actions and recovery actions e.g. T3/T4 recovery.
Automatically unlocked for recovery and must be
manually relocked afterwards.
