Long Description
The specifications displayed below are for the entire series of products and may not apply to this product or model, please refer to the above description for the correct details of this model.
Overview:
Designed for NVMe-based SSDs in HP's Z4, Z6, and Z8 G4 Workstations running Windows 7 or 10, and Xeon Skylake-W or Skylake-SP processors, this premium version of the Intel VROC for NVMe from HP is an enterprise RAID storage solution that supports RAID 0, 1, 5, and 10 and lets users manage RAID volumes with NVMe SSDs that are directly connected to CPU PCIe lanes, without using a host bus adapter (HBA). Short for Virtual RAID on CPU, the Intel VROC delivers faster performance without the complexity and power of a traditional Hardware RAID HBA.
Features:
General Features
- No need for battery backup / RAID maintenance free backup unit
- Protected write back cache - software and hardware that allows recovery from a double fault
- Isolated storage devices from OS for error handling
- Protected R5 data from OS crash
- Boot from RAID volumes based on NVMe SSDs within a single Intel VMD domain
- 3 VMD domains per CPU provide for boot from one domain and data RAID spanning across the other 2 domains
- RAID / storage management using representational state transfer (RESTful) application programming interfaces (APIs)
- Graphical user interface (GUI) for Linux
- 4K native NVMe SSD support
Key Feature List for Workstations
- Boot RAID (0, 1, 5, and 10) on CPU-attached NVMe RAID volume
- Close the RAID Write Hole - Helps to recover writes that may not have been written during a power loss condition while the system is in a RAID 5 rebuild
- Spanning data RAID volumes across VMD domains
- For NVMe RAID, Intel VROC is architected to use Intel VMD to provide the following features that Intel RSTe legacy NVMe RAID does not have:
- Bootable RAID
- RAID 5 Double Fault Protection
- Support for HP-qualified SSDs, as well as Intel SSDs
NVMe RAID Features
- CPU attached NVMe SSD - high perf
- Boot on RAID volume
- Third party vendor SSD support
- Intel RSTe 5.0 RAID 0, 1, 5, and 10
- RAID write hole closed (BBU replacement)
- Hot plug / surprise removal (2.5" SSD form factor only; Add-in card form factor not supported)
- Enclosure LED management
