IBM GPFS / Spectrum Scale Alternative and Comparison

What is IBM SpectrumScale / GPFS

SpectrumScale, initially called GPFS, was developed over 25 years ago as the enterprise’s first distributed software storage solution. The primary purpose was to coordinate the concurrent access to a SAN (storage area network, see here) from many clients.

SpectrumScale vs. Quobyte: How they compare

The architecture is one of the main differentiators between Quobyte and SpectrumScale. The coordination of the block access limits the scalability of a SpectrumScale cluster. Even worse, SpectrumScale clients can hold locks as well. When clients get disconnected or crash, it causes the unavailability of portions of the file system.
