We have two appliances — a primary and a secondary — and they are synchronized, so all the volumes are replicated. If the primary appliance goes down, we can get functions on the other side. When it's writing on one side, writing is disabled on the other side. In the event of disaster recovery, we can enable writing, and then we can do anything from there.
Most of our PowerStore units are used for VMware VMs and vSphere. We migrated the VMs from our Unity storage. We have two sites; the data center site (DC) and the disaster recovery (DR) site. We only use the PowerStore on the DC site. The project was put on hold due to COVID but we plan to continue with it this year.
We use it for machines from VMware vCenter which we keep separate from the PowerStore. It is only the storage. They are connected with iSCSI and NFS. We have no virtual machines directly on the PowerStore.
We are a cloud service provider and we use Dell EMC PowerStore for the storage.
PowerStore is joined to four application servers in a cluster. We're running an application that we use to monitor our activity in the financial markets. We collect all the data from the market—books, trades, orders—that we send to the market. In terms of volume, we are collecting about 100 million rows a day for the books, 10 million a day for the orders, and about 500 rows for public trades. It is a mission-critical application because of compliance and the regulators. We have to maintain this kind of monitoring because it's a direct link to our activity in the regulated market.
We were in need of a new enterprise storage solution for our virtual machines. We use it for primary systems and processes, so for us it's very important.
The use case for this solution is based on VMware and that is why we chose PowerStore X. During the first period of the pandemic, we decided to use our VMware infrastructure for HPC workloads. We were looking for high-performance storage that could be inserted inside our VMware environment in an easy way. PowerStore, which had just been announced, seemed like the right solution and so we decided to buy. We have this storage environment inside the virtual HPC. In our environment we are doing medical analysis related to genomic workloads. The data are acquired remotely from experiments and stored on the PowerStore. The PowerStore is exposed to the user through virtual machines, and the data are analyzed in this environment.
Which is better?
I'm researching flash storage arrays. I'm looking for advice about which of these two options is better - IBM flash 9200 or EMC VMAX8000.
