Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
NetApp AFF needs improvements in setup, support, integration, performance, flexibility, latency, monitoring, and management for competitive advantage.
VMware vSAN requires better management tools, integration, and hardware support, with improved stability, scalability, and enhanced disaster recovery features.
One way to improve the product is to add an operational assistant that doesn't depend on VMware.
Sales Manager at Multicomputos PR
I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert.
Cloud Architect at DXC Technology
Storage replication should be essential.
Infrastructure Specialis at a tech services company with 1-10 employees
The GUI of ONTAP Command Manager could be better, but the CLI is perfect.
Senior System Engineer at a tech services company with 51-200 employees
Our backup system, Commvault, has an amazing capacity to do compression and deduplication better than NetApp AFF by itself.
Analyst at a manufacturing company with 1,001-5,000 employees
All of this is the same for all product ranges, whether E-series, NetApp AFF, or FAS series, because they are very efficient to respond.
IT Manager at Synergy Computers
A proper monitoring tool that encompasses both applications and infrastructure would help in quickly resolving issues.
Sr Service Engineer at a healthcare company with 1,001-5,000 employees
I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features.
Associate Tech Specialists at Seatrium
Discussing the pricing model is significant as Broadcom creates many discussions worldwide regarding pricing.
Senior Infrastructure Consultant at a tech services company with 11-50 employees
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
NetApp AFF offers competitive value with features included, often more cost-effective than Oracle and EMC for comparable performance.
VMware vSAN offers long-term savings, but initial costs and licensing complexity concern small businesses, especially post-Broadcom acquisition.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
Manager, System Infrastructure & Security at Organik Kimya San. ve Tic. A.S.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
Sales Manager at Multicomputos PR
NetApp support is cheaper than Dell support.
Senior System Engineer at a tech services company with 51-200 employees
While it is not cheap, they have introduced a new series of AFF that are more affordable.
Analyst at a manufacturing company with 1,001-5,000 employees
The licensing cost of the product is expensive, and when combined with support, it becomes quite costly.
Presales Manager at Spartec
This has resulted in a slight cost increase.
Sr Service Engineer at a healthcare company with 1,001-5,000 employees

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Offers seamless installation and efficient data handling with robust support
NetApp AFF provides an all-flash storage solution for unified SAN solutions, supporting both SAN and NAS functionalities. Data reduction capabilities such as deduplication, compression, and compaction are standard features included with the license in NetApp AFF. With the storage efficiency from a NetApp AFF installation, users can manage substantial data running on all-flash. The features such as compaction and compression provide storage efficiency guarantees in an all-flash environment.

Managing mixed RAID workloads has improved data protection and delivers strong performance
VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
