Hi! adding to what @GorazdKikelj suggested (high end Comware DC versus high end Aruba CX DC switches) and your initial "stackable switch" requirement: Comware suggested models support IRF technology [1] (multi-members) technology and DRNI [2] (2 members only) technology while the Aruba CX suggested models support VSX [3] (2 members only) technology.
The IRF, DRNI or the VSX could/couldn't be what you're exactly looking for in a Switch when you refer to "Stacking switch": that's especially true if you don't clarify what do you mean with (and what do you require by a) "stacking" solution (as example: how many members the Stack should have at minimum to fulfill your networking/connectivity/resiliency requirements?).
Cheers!
[1] Intelligent Resilient Framework (IRF) technology is developed by HPE to virtualize multiple physical devices at the same layer into one virtual fabric to provide data center class availability and scalability. IRF virtualization technology offers processing power, interaction, unified management and uninterrupted maintenance of multiple devices. Devices attaching into the IRF stack can be any device as normal (possibly multi-homed via LACP LAGs).
[2] Distributed Resilient Network Interconnect (DRNI) is a IEEE standards based solution which allows two physical switches to be virtualized into a single distributed-relay (DR) system which is able to connect to remote devices through a multi-chassis aggregate link. To the remote device the DR system appears and behaves as a single device. While standards based, the pair of physical devices to be deployed into a DR system will only work with FlexFabric switches. Devices attaching into the DR System can be any device as normal (possibly multi-homed via LACP LAGs).
[3] Aruba Virtual Switching eXtension (VSX) is virtualization technology for aggregation/core switches running the AOS-CX operating system. This solution lets the switches present as one virtualized switch in critical areas. Configuration synchronization is one aspect of this VSX solution where the primary switch configuration is synced to the secondary switch. This solution allows for a pseudo single plane of glass configuration and helps keep key configuration pieces in synchronization as operational changes are made. Since the solution is primarily for high availability, it is expected that most of the configuration policy is the same across both peers. VSX virtualizes the control plane of two aggregation switches to function as one device at layer 2 and as independent devices at layer 3. From a datapath perspective, each device does an independent forwarding lookup to decide how to handle traffic. Some of the forwarding databases, such as the MAC and ARP tables, are synchronized between the two devices using a proprietary VSX control plane. Some of the forwarding databases are built independently by each switch. Devices attaching into the VSX Cluster can be any device as normal (possibly multi-homed via LACP LAGs).

Data Centre Aggregation Switch Specification
Could you please suggest which switch would be suitable for our requirements?
- Stackable switch that supports minimum 32 x 100 Gbps QSFP28 ports (optionally configurable to 64 x 40 Gbps or 128 x 10 Gbps SFP+ ports)
- Included minimum and 8 x 10GE SFP+ ports
