Two products are featured in detail in this section, MoonWalk and Managed Server HSM. While not discussed here, IBM's Spectrum Protect has an HSM component.
Moonwalk Universal is an Australian software company and it supplies the Moonwalk HSM product, discussed in a bit more detail from the link below.
Moonwalk supports Microsoft Windows Servers from versions 2012 to 2019 using NTFS and ReFS filesystems, NetApp ONTAP 9 Filers, Micro Focus Open Enterprise Server OES2015 Linux NSS and Dell EMC Isilon SMB Shares.
Managed Server HSM from Camino Software is a pure HSM product. It can manage Windows versions from 2000 to at least 2012 and also Apple-MAC, NetApp and OES Linux servers as clients, and either needs cheap disk installed on the network, or it can write to a TSM interface or an EMC Centerra.
The Key to MSHSM is the 'Policy Engine'. This contains sets of Migration Profiles and Volume Rules.
The following page shows examples of defining a Migration Policy, including Migration rules, Deletion policies, and Volumes Rules.
