Find out what your peers are saying about NetApp, IBM, Hewlett Packard Enterprise and others in Modular SAN (Storage Area Network)."The most valuable feature is that maintenance is free."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
"The solution is very easy to configure and use."
"It's a mature product. It's like a BMW that evolves consistently."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"User friendly management interface."
"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."
"The maintenance service and support from IBM is very good."
"Flash disk with Easy Tier option"
"The pricing is reasonable."
"Multi-tiering, positively affects the efficiency of the storage space."
"Good performance for VM environments"
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"It is very stable, even during multiple power failures."
"I really value deduplication and compression to save space."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"It is very stable even during multiple power failures."
"They could improve the price."
"Storage. There could be better storage."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"The price is very costly."
"The solution's pricing is a bit high so there is room for improvement."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"The product needs to improve their scalability."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"Poor connection to FC."
"The CLI could be better documented, like with VMAX."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
