The 3PAR flash storage is perfect for use cases that need high I/O and low latency (like data bases or even VDI). The flexibility of the system allows you quickly to allocate or expand storage. I would not recommend it for use in archival storage (too expensive) or for systems that have very low I/O requirements.
Replication - HPE 3PAR offers exceptionally fast and well-managed replication with little latency and that's why we bought it to store and protect our most important ERP data. We wanted identical performance and connectivity for our primary storage and our failover (DR) storage and so we bought two of them.
Hybrid storage is right up HPE's alley. You can assign different roles to different types of storage arrays inside one enclosure, for instance, you can store your data that needs super high availability and fast IOPS on an all-flash volume but on the same shelf you can have a platter array for longer-term and less- time-critical data. This saves a lot of money on the front end because you don't have to buy all-flash. Why go all-flash for that data where you aren't going to need it?
3PARs can do both file-level and block-level replication which is nice.
The data compression/compaction is really very good.
No SNMP Support: You can monitor almost every device nowadays with SNMP, but 3PAR does not support it. You have to buy HP Openview, which costs extra and does not integrate well with your already existing monitoring solution.
No NFS Support: HP provides an ugly workaround by deploying a VM onto 3PAR that then provides the assigned storage as NFS storage.
Only expensive SSDs can be run.
Upgrading the storage with new firmware is a horrible process. They assist you with a support center based in India. Just picking an appointment is a hassle. They send you PDFs that look like they have been created by children, with red circles and yellow highlights. You have to go through the whole update routing every time. Even if you already did the routing last time and are now only upgrading a minor release.
Outdated management application: The application looks like it was developed 20 years ago. It is very unintuitive. They announced that you can manage 3PAR over the web, but it is all again just an ugly workaround. You have to install an application that runs on a web server locally, so you cannot access the management via web from everywhere. The web overview looks nice and is intuitive, but it does not provide all the features. You still have to go to the old application for lots of things.
The compaction value is just marketing. If you deploy a disk of 100GB and only have data of about 10GB, 3PAR calculates the unused 90GB into the compaction value. This is just for show and does not provide any "space savings." Dedup is where the real savings come in. Depending on the type of data, we have a dedup ration between 1.3:1 and 4.4:1 on our VVols.
We are very satisfied with 3PAR performance and especially the IOPS (Input Output Per Second) is pretty amazing. It is easy to configure and doesn't require much knowledge of storage for Tier 1 support team.
This was one area of real disappointment. EMC support was very slow to schedule work like installations and upgrades. Break/fix support was fairly standard. After the Dell merger, things have started improving but there is a lot left to be desired here.
At the time the EMC was selected due to the existing relationship with EMC and the maturity of their product compared to the other vendor's options. However now that the maturity gap has been closed and the storage wars have proven which companies will remain for the foreseeable future, we have decided to move away from the XtremIO and go with an alternate storage company due to the price and cost of ongoing support. The EMC product is still a great product, I just find it too expensive to purchase and maintain in today's competitive marketplace.
We also considered NetApp All-Flash FAS since it works on similar technology and provides comparable throughput. However, we were offered better deal from HPE as we are existing customers for HPE, hence we chose HPE 3PAR StoreServ.
HPE 3 PAR has quickly proved its value to our organization. I cannot speak to ROI, but feel that it has quickly met the expectations of our organization.
The 3PAR has allowed our organization to expand business due to its ability to be expanded with no downtime.
