In this version of the VNX, the maximum size of a file system is 16TB. The maximum number of read-only checkpoints per file system is 96 and 16 writeable checkpoints. The maximum number of physical drives in the VNX5700 is 500. However, you can work with EMC and ask them for RFQ to go beyond the number of physical drives to add a few more.

No issues in scaling up, but there is no way to reduce the size of a storage pool.

Yes, this solution is sensitive to scalability in the sense that you require certain proportions of all three tiers of disk if you enable Auto-Tiering. This resulted in performance issues with the mid-tier having insufficient capacity. The array was thrashing to attempt to use 7200 RPM SATA disks in the lowest tier since they had the capacity. This was disastrous and EMC would not even acknowledge the issue until they forced us to prove it.

There were scalability issues, the scalability options are limited due to supported SSD.

We did purchase additional shelves of drives a few years after the initial purchase. Again, with the support of EMC technical services, the hardware was added to the VNX without downtime or disruption. The Storage Pools allow for dynamic addition of new drives.

We have not encountered scalability issues, but then we did not try to use VNX beyond its target application range.

It’s definitely scalable. VNX to large SAN with SDD to all with extra storage for VDI, they’re all hugely scalable. You can keep adding blocks of storage for different tiers, as well as sites of storage, with other products (replicated with backups).

We have not yet encountered any scalability issues in our environment.

No issues.

No issues with scalability.

I did not encounter any scalability issues.

We have had some scalability issues. Scalability options are limited due to the supported SSDs.

There are upper limits, but these are rarely reached depending upon the VNX model being used.

No issues encountered.

In comparison to other products, VNX scales out well.

No. Very easy to scale, both capacity and performance-wise.

We did not encounter any scalability issues.

No issues. It has always been used in small isolated environments.

We encountered scalability as it is limited by backend slots, and NAS performance is significantly reduced when scaling.

It is easy to scale.

No issues.

It’s amazing, you can add and stack, and add more elements. You can group to scale horizontally and vertically, can add VMware tech, can add flash arrays, and everything integrates seamlessly. The intelligence controls everything. I don’t worry about infrastructure and I don’t have to move to the cloud.

No issues encountered.

No, it's easy to upgrade and expand.

There were no scalability issues.

No, it is easily scalable.

Not in this case, but it has its limits based on the model you chose.

We don't have any case where we need to add more storage on this product.

The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations. So the scalability is a little bit limited. But that has been improved in the new storage family called Unity.

Yes, we have had issues. The system is limited by the number of enclosures.
