Room For Improvement

IBM FlashSystem requires enhancements in scalability, integration, user interface, and support, with better deduplication, monitoring, and streamlined processes.
Panzura CloudFS users seek improved performance, flexibility, stability, UI, analytics, support, and pricing for enhanced deployment and management.
Despite marketing promises, these features do not function effectively and can impact performance.
Vice President Sales at BELOCAL LTD
There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight.
Manager, Technical Services, IBM Storage & Backup Solutions. at Thakral
An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated.

CIO at Mead and Hunt, Inc.
The GIS data formats, such as a geo database, have been found better kept outside of Panzura CloudFS.
Senior Vice President, Technology at Halff Associates, Inc.
 

Setup Cost

IBM FlashSystem offers competitive pricing, but evaluating long-term needs and negotiating discounts is crucial to manage costs effectively.
Panzura CloudFS pricing is competitive but expensive, requiring new hardware and lacks flexibility for volume licensing beyond 25 terabytes.
To install or upgrade any software features, the cost is high, which makes it challenging for smaller companies who do not require advanced features like deduplication or compression typically needed by larger organizations.
Vice President Sales at BELOCAL LTD
The pricing is high; storage solutions are always expensive.
Freelancer at a logistics company with 10,001+ employees
It did require us to purchase new hardware, however, that was not overly expensive.
Senior Vice President, Technology at Halff Associates, Inc.
They should consider more attractive pricing for companies of our size.
I.T. Infrastructure Manager at Thompson Engineering, Inc.
Overall, it is quite costly compared to NetApp and similar solutions.
Technical Expert at a manufacturing company with 10,001+ employees
 

Valuable Features

IBM FlashSystem delivers high performance, user-friendly management, and scalable efficiency with robust features like deduplication and virtualization.
Panzura CloudFS provides efficient collaboration, robust data protection, and seamless global file access with advanced synchronization and security features.
There is a significant amount of data reduction, achieving a ratio of one to three.
Storage Specialist at a computer software company with 1,001-5,000 employees
The most valuable features are performance and reliability.
Freelancer at a logistics company with 10,001+ employees
There is built-in compression, a data reduction feature, and artificial intelligence-driven insights that calculate warnings and errors to redirect to customers automatically.
Manager, Technical Services, IBM Storage & Backup Solutions. at Thakral
It is very reliable and very quick.
CIO at Mead and Hunt, Inc.
It helps us increase network resilience. We have a primary object library stored in the cloud and have Panzura Mirroring which allows us to place data in a secondary cloud for added resiliency.
Senior Vice President, Technology at Halff Associates, Inc.
There is no degradation of speed because these filers have cached the data, and they are constantly swapping metadata and updating with each other, which is a very attractive method of getting us to use these applications.
I.T. Infrastructure Manager at Thompson Engineering, Inc.

Featured Reviews

OmarIsmail1 - PeerSpot reviewer
Infrastructure Technical Specialist II at Clicks Group
Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.
Anil Rahulwar - PeerSpot reviewer
L3 Storage Engineer at Capgemini
Global collaboration on large design files has become faster, more secure, and reliably governed
Improvements for Panzura CloudFS can be challenging, as the product is very powerful, but performance at scale sometimes requires tuning. Some organizations report latency spikes when handling extremely large datasets with high concurrency. Improvements in real-time sync speed are required. Stronger support for multi-cloud or hybrid deployments would reduce vendor lock-in, and enhanced security could include expanded zero-trust access controls. Enhancing real-time sync speeds across continents and built-in metadata tagging for smarter queries would also be beneficial. Additionally, while Panzura CloudFS is optimized for office and edge clients, more native mobile apps or lightweight remote access options would facilitate secure collaboration for field teams. Automatic file tagging or classification would expedite searching across millions of files.
