"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"Its scalability has been huge for us."
"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."
"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."
"The stability of the solution is good."
"I don't have to rebuild the cluster to add a node."
"This is a stable solution."
"The initial setup was straightforward."
"The solution is stable."
"We never had a blackout and we have never been offline."
"Their support is the most valuable. The support that we are getting from HP Turkey is very good. This product is better than some of the other products in terms of reliability. It is very reliable."
"3PAR is different from other storage solutions because it uses a chunklet when we initiate the storage. Every disk is submitted as a 1 GB chunklet. This chunklet can be RAID 1, 4, 5, or 6. This fabulous feature is very useful for me because I can distribute the RAID for any volume. The adaptive optimization is the biggest feature in 3PAR. 3PAR is very usable with thin volume because it detects zeros while writing. Every time I tell the hypervisor to make the full provisioning, it makes the volume as simple provisioning in 3PAR, not full provisioning. Other vendors take this volume as thick provisioning because of which the capacity is reached quickly. It doesn't happen in 3PAR because it detects zeros. It only writes the data, and it doesn't write zeros. There are two processors in 3PAR: the ASIC processor and the main processor. The ASIC processor detects zero writing and doesn't write it, which is a big feature in 3PAR."
"We're hosting virtual infrastructure on the 3PAR storage and it's been very good for that."
"HPE 3PAR StoreServ is easy to use and has good performance."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"It is a bit higher priced than some of the other systems."
"The replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement."
"The solution can be a bit complex for those not well versed in the technology."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."
"The configuration and flexibility should improve."
"This solution only provides active-passive replication, as opposed to active-active."
"There are issues formulating the upgraded disk."
"The solution lacks reliability."
"HPE 3PAR StoreServ could have better integration into the cloud and converged infrastructure."
"HPE 3PAR StoreServ has limited flexibility in building replication solutions. There are limitations to the number of IOPS the system can do. It's not bad as it is doing its job. However, for the application, if you need a toolbox, you can build everything concerning periodic replication modes of synchronous or asynchronous three-site, four-site, with supported cascading which requires you to buy an IBM product. It also takes a few hours to one day to upgrade the system and sometimes; it takes more time because, in some HPE 3PAR StoreServ 20000 Storage, you have an eight-node system. If you do an upgrade, you do it node by node and every node might take more than an hour."
"HP has several integration elements that work with other vendor storage products. I'd like to see a greater expansion on that so that a customer can do a more seamless migration from other vendor products."
"Although we experienced malfunctions where a virus was running and it failed."
