Массив памяти корпоративного класса HP VMA3205/VMA3210 включает аппаратный RAID на базе модулей flash-памяти с поддержкой "горячего" подключения для обеспечения надежной защиты данных и беспиковых задержек, длительностью менее 100 микросекунд.
Возможности:
NAND memory | Single level Cell (SLC). SLC stores one bit per cell and has higher endurance characteristics than Multilevel Cell (MLC) technology. |
PCIe direct attach | PCIe Gen 2 x8 interface. |
SAN Gateway accessory |
2U rackable appliance with factory-installed VMA controller and management software.
Options:
|
Block Mode |
4KB recommended; 512B supported |
RAID | 4+1parity RAID over multiple memory modules, pre-defined, no user options. Memory module sparing |
Reliability | 24 bit error correction per 4K block (ECC) Additional 128 bit integrity check over 4K block |
Performance | PCIe direct-attach or 8Gb Fibre Channel SAN attach: Up to 350K IOPS Read (4K block) |
Up to 250K IOPS Write (4K block) | |
Latency |
Less than 100 microseconds of latency in PCIe-direct attach operation |
Bandwidth | PCIe direct-attach or 8Gb Fibre Channel SAN attach: 1.4GB/s bandwidth |
Wear-leveling | On-board processing for garbage collection (reclamation of locations with stale data) and wear-leveling (distributing re-writes and erasures evenly to minimize wear) without using the host's CPU cycles provides VMA systems with sustainable I/O performance over time. |
Endurance | Up to 8TB writes per hour for 5 years (VMA3210) Up to 4TB writes per hour for 5 years (VMA3205) |
On-line memory module replacement | Hot-swappable VMA memory modules. To ensure proper system cooling, the unit cover cannot be open for more than 2 minutes. |
