Other controller functionality includes compression, data deduplication, thin provisioning, all in real time. Modification of data in a block creates a new block in free space, then erases the existing block when there is sufficient compute available. Instead, data is striped between a number of shelves to cut down on latency.
There isn’t one volume pere disk or SSD in a shelf. The controllers make intensive use of their RAM and Optane modules to store metadata that allows for rapid access to data blocks. Each controller transmits data over the network at a speed of 9GBps and with latency in milliseconds, which is via 100Gbps Ethernet or 32Gbps Fibre Channel. According to NGX, it’s possible to grow to 20PB of capacity and only deploy two controllers. So, you can have more controllers to maximise parallel access, more shelves of SSD to boost speed, or more HDDs to maximise capacity. The architecture allows for this or that component to grow depending on need. From the controller point of view, storage nodes look like their internal drives, and comprise SSD and/or HDD capacity. On the network, controller nodes share access and handle data transport to and from storage nodes via Ethernet RoCE switching and Infiniband. They can be operational five minutes after unpacking.” We are open to requests for customisation and we think our arrays are among the easiest to use. “But our production is local, reactive, and without supply problems to European customers.
“We won’t pretend we’re cheaper that the US vendors,” said Yurtseven during a recent IT press tour event. Research institutes use file mode for their VMs in OpenStack and block for volumes shared between compute nodes in Lustre.” “Hosting providers use block mode for VM disk images and file for video storage. “The banks use our products as SAN for databases and as NAS for their developers,” said Ali Kemal Yurtseven, director general of NGX. Bulk storage is on spinning disk after passing through a number of levels – SSD, Intel Optane, RAM – of which the profile can vary depending on application requirements. NGX offers storage array products for a variety of performance levels and workloads.
