IBM FlashSystem Reviews Summary
Author infoRatingReview Summary
Infrastructure Technical Specialist II at Clicks Group4.0I find IBM FlashSystem to be a competitively priced, reliable storage solution offering robust performance on demand. However, its deduplication technology requires improvement, especially compared to alternatives like NetApp. The return on investment is immediate, and the hardware is dependable.
Storage Specialist at a computer software company with 1,001-5,000 employees4.5I use IBM FlashSystem for CRM, billing, and telecom industry tasks, along with code and case management systems, and some customers use SAP HANA. The performance and data reduction are impressive, though the GUI and volume deletion time could improve.
Freelancer at a logistics company with 10,001+ employees4.5I've found IBM FlashSystem to be reliable and high-performing, with simple management via SVC. While the price is high, it’s justified by its features. I’d rate it eight out of ten overall for on-premises SAN storage.
Vice President Sales at BELOCAL LTD4.0I am working with IBM FlashSystem 5300, ideal for small companies with storage needs up to 16 terabytes. It is cost-effective but needs improvement in deduplication and compression. We also offer Hitachi and Dell for better performance and reliability.
Manager, Technical Services, IBM Storage & Backup Solutions. at Thakral4.0I use IBM FlashSystem primarily in the banking industry for its flash copy mapping and built-in compression, despite challenges with troubleshooting and high licensing fees. Its scalability and support make it a preferred choice over Dell, Huawei, and HP.
Technical Lead at Tomia3.5I've used IBM FlashSystem for over seven years and found it reliable with good performance and reasonable pricing, though support response times need improvement. It's ideal for medium workloads, and we've seen a solid ROI after three years.
SENIOR SYSTEM ADMINISTRATOR at TOTAL SERVICE a.s.4.0I use IBM FlashSystem for customer data and backup due to its ease of updates and setup compared to previous Storwize experiences. Although the system works fine, its customization features need improvement. HPE remains a notable competitor.
Sr. Manager - System Analyst (Datacenter Infrastructure) at Sohar International3.5Our company utilizes IBM FlashSystem for robotic process and workflow automation, as well as document management. The storage system is straightforward with an easy-to-use GUI and tier replication capabilities, but lacks compression and deduplication, limiting memory and controller power.
