RoCE or roll in the general, er, Vcinity: Thousand mile-plus RDMA makes remote editing seem local

San Jose peeps tout distance-killing file data access
California networking startup Vcinity said this week that its networking products shunted a petabyte of data 7,000km in under 24 hours, providing access to remote files thousands of kilometres away with a 250ms round trip time.
How does Vcinity explain its hardware and software driving a link so fast? The firm said it used a patented Global Fabric Extension technology with Ultimate X (ULT X) software and RDMA (Remote Direct Memory Access). It claimed it can use up to 95 per cent of a link's available bandwidth but did not explain how.
ULT X presents itself outwardly as a NAS (NFS v3/4 and SMB v3) or transitional storage tier, and has a global namespace and network-mapped drive volumes. Vcinity said it is compatible with various storage systems for file storage.
The product set includes:
- ULT X software in on-premises Linux server or as software-only to run in the cloud
- RAD X PCIe gen 3 cards
- X-1010e (1/10Gbit/s)
- 1040 (1/10/40 Gbit/s and FDR InfiniBand)
- 1100 (1/10/40/100 RoCE and FDR/EDR InfiniBand)
- Command X web-based GUI management facility included with ULT X
- Access X file management and sync tool to copy and move folders
- Sync X is a web-based file synchronisation and backup tool
The RAD X cards need ULT X software on their host server and use RoCE (RDMA over converged Ethernet) or InfiniBand over any layer 2/2.5/3 network with traffic engineering and congestion management of flows across the network.
This kit is only available from Vcinity's channel partners.
Noboru Aoki at Core Microsystems said of the tech: "For our Media and Entertainment clients, the Vcinity Ultimate X solution allows video producers to edit remote content across any distance as if it were local to their desktop.
