Scalable multiserver cluster: different physical and logical servers (web, mail, DNS etc.) are managed from one control panel. More servers can be added on the fly.
Multilingual support includes English, German, Dutch, French, Italian, Spanish, Russian, Portuguese (Brazil), and several other languages integrated by means of add-ons.
H-Sphere is recognized for end-user features availability, such as mail system, site building tools, SSL, etc. "Beginning webmasters may find H-Sphere too complicated for their needs. More advanced users, however, appreciate the features and control that H-Sphere offers the end user."
H-Sphere may give place to other panels as regards its ease of use, but not its online documentation.
H-Sphere has enlisted a community of online supporters who name it among their favorite control panels.
Licenses for H-Sphere accounts are more expensive than those of its competitors. Though, it is noted that H-Sphere licenses are reusable and sold for a cluster, not for a server, as with Ensim Pro.
Some customers state H-Sphere has too many advanced features and thus is a too complicated solution for small hosting companies, especially as a single server installation. While others note that H-Sphere advantages are more demonstrable on multi-server clusters.
On a single server mode H-Sphere consumes more server resources than other major single server control panels.
H-Sphere control panel by default works on non-standard 8080 and 8443 ports that may be blocked by client-side firewalls; but this can easily be changed in the configuration.
H-Sphere does not provide a comprehensive tool for its backup.
H-Sphere (like cPanel, but unlike Plesk) provides online file source editing, however with H-Sphere only allows editing of .txt or .html files and without line numbers in edit mode, thus limiting PHP and other script editing possibilities.
