Feature name	Feature description
Open Minimally Disruptive Migration support (OMDM)	A new Data Migration feature Open Minimally Disruptive Migration (OMDM) is introduced to help automate the process of moving applications from XtremeIO, VNX, Unity, V2, DMX and other array vendors to PowerMax 2500 and PowerMax 8500 arrays. NOTE:OMDM migration requires a short application downtime.
Deprecate TF Mirror, TF VP Snap, TF Snap	A new enhancement is introduced to block the TimeFinder/Mirror and TimeFinder/VPsnap control actions for arrays running PowerMaxOS 10 (6079). The symclone user options pre-copy, nocopy, and nondifferential are no longer supported for arrays running PowerMaxOS 10 (6079), as symclone sessions on these arrays is always differential.
Platform readiness to support 4k snaps/clones per volume	A new infrastructure is provided to support 4k snapshots per device when it becomes available. Support is added for 256 clones per source device for arrays running PowerMaxOS 10 (6079) and higher. The command symclone is enhanced to support 256 clones per source device for arrays running PowerMaxOS 10 (6079) and higher.
Support for SnapVX Direct Mapped Architecture	A new SnapVX Direct Mapped Architecture (SDMA) is introduced for the local replication for arrays running PowerMaxOS 10 (6079) and higher. The new SDMA architecture allows the symclone to leverage the same sharing infrastructure as SnapVX snapshots, helping Symclone to be as space efficient as SnapVX. The symsnapvx CLI is enhanced to allow the users to work with SDMA used by local replication for arrays running PowerMaxOS 10 (6079) and higher. The use of -copy with link/relink copy action is optional on arrays running PowerMaxOS 10 (6079). The symsnapvx link target states report only the Copied or CopyInProgress state for all link/relink actions with and without the -copy flag. The Copied state is used to indicate the data is available on the target device, otherwise the InProgres state is reported. This CLI is enhanced to report copy progress indication by overloading the existing DEFINE in progress flag when working with arrays running PowerMaxOS 10 (6079) and higher.
SG support for symclone	Support is added for the TimeFinder symclone control and query action with SG on arrays running PowerMaxOS 10 (6079) and higher. NOTE:The Create, Activate, Recreate actions are not supported with SG input.
Emulation Convergence	From PowerMaxOS 10 (6079), infrastructure changes allow multiple emulations to run on a single instance. This Emulation Convergence allows optimizing CPU and memory resource usage when different connectivities exist on the same board within the array.

OpenSSL	OpenSSL used in data encryption, has been updated from 1.0.2l to 1.0.2.zd, which includes bug and security fixes.
ACL Deprecation on PowerMax 2500 and PowerMax 8500	Symmetrix ACLs (symacl) are not supported on PowerMax 2500 and PowerMax 8500 arrays. Customer access control on PowerMax 2500 and PowerMax 8500 arrays is handled entirely via User Authorization (RBAC, symauth). NOTE:With the exception of symauth -unique, any invocation of the command symacl against a PowerMax 2500 or PowerMax 8500 array fails with a not supported error.
RBAC Usability Improvements	With the deprecation of ACL support for PowerMax 2500 and PowerMax 8500 arrays, improvements are added to RBAC. The output for the command symauth list -users is modified to omit the obsolete No Effect flag unless the -mode V92 argument is provided.
SSC Access for Unisphere on EEM Guests	Unisphere is enhanced to provide functionality formerly available through vApp Manager. To support this, Solutions Enabler V10.0 provides access to Unisphere through a Secure Symetrix Credential (SSC) when running on the EEM guest.
User Identities on Embedded Guests	From Solutions Enabler V10.0, users who have explicitly logged onto an embedded Guest (PowerMaxOS 10 (6079)), their user identity now reflects the type of Guest and Array ID.
Access IDs for Embedded Guests	For embedded Guests on PowerMaxOS 10 (6079) arrays, the same Access IDs are generated for both instances of the Guest. Both instances of the Unisphere Guest use the same Access ID Both instances of the SE-MGMT Guest use the same Access ID Both instances of the SE-TOOLS Guest use the same Access ID Both instances of the VASA Guest use the same Access ID Arrays running HYPERMAX OS 5977 or PowerMax OS 5978, a different Access ID was used for the two instances of each Guest. These Access IDs are used with operations initiated from these Guests.
Access Control for Clone Operations	To support Clone operations, the following improvements are added: Clone operations performed against SGs: The operation is allowed if the user has been granted these rights to both the source and target SGs, or the entire array. For operations performed against devices from a device list, DG or CG: The operation is allowed if the user has been granted these rights to the SG(s) that both the source and target devices belong to, or the entire array. For Clone operations, LocalRep (Local Replication) rights are required.

Feature name	Feature description
SRDF enhancements	Solutions Enabler V10.0 includes the following SRDF enhancements: Arrays with PowerMaxOS 10 (6079) and above can have a maximum of 2048 SRDF group. Arrays with HYPERMAX OS 5978 or 5977 hybrids only can have a maximum of 250 SRDF group. Arrays with PowerMaxOS 10 (6079) and above can have a maximum of 2048 SRDF groups per director/port. Arrays with HYPERMAX OS 5978 or 5977 can have a maximum of 250 SRDF groups per director/port. Arrays with PowerMaxOS 10 (6079) and above can have a maximum of 65536 devices per SRDF director/port. All supported arrays running Solutions Enabler V10.0 can have a maximum of 65536 devices per SRDF director/port. NOTE:When creating an SRDF group between two arrays, the largest SRDF group number which can be used is governed by the array which supports the smaller number of SRDF groups. Therefore, when creating an SRDF group between a PowerMaxOS 10 (6079) and HYPERMAX OS 5978, the largest SRDF group number that can be used is 250.
SRDF consistency	When enabling SRDF Consistency CGs, if the CG contains arrays with PowerMaxOS 10 (6079) and above, the enable is only allowed if: All RDF groups are less than or equal to 250 Arrays are a mixture of PowerMaxOS 10 (6079), and/or HYPERMAX OS 5978 with fix 105197, and/or HYPERMAX OS 5977 with fix 105197 or At least one RDF group is greater than 250 All arrays are HyperMaxOS 6079 and above or At least one RDF group is greater than 250 Arrays are a mixture of PowerMaxOS 10 (6079), and/or HYPERMAX OS 5978 with fix 105197, and/or HYPERMAX OS 5977 with fix 105197
