About the hardware
The Hitachi Virtual Storage Platform G350, G370, G700, G900 and the all-flash Hitachi Virtual Storage Platform F350, F370, F700, and F900 are rack-mountable storage systems that incorporate state-of-the-art virtualization and advanced data-management and fault-tolerant technologies.
Hitachi Virtual Storage Platform G/F350, G/F370, G/F700, G/F900 hardware overview
The architecture of the Hitachi Virtual Storage Platform G350, G370, G700, G900 and Virtual Storage Platform F350, F370, F700, F900 models accommodates scalability to meet a wide range of capacity and performance requirements. The storage systems can be configured with the desired number and types of front-end module features for attachment to a variety of host processors. All drive and cache upgrades can be performed without interrupting user access to data, allowing you to hot add components as you need them for pay-as-you-grow scalability.
The Hitachi Virtual Storage Platform G350, G370, G700, G900 and Virtual Storage Platform F350, F370, F700, F900 models have dual controllers that provide the interface to a data host. Each controller contains its own processor, dual in-line cache memory modules (DIMMs), cache flash memory (CFM), battery, and fans, and is provided with an Ethernet connection for out-of-band management using Hitachi Device Manager - Storage Navigator. If the data path through one controller fails, all drives remain available to hosts using a redundant data path through the other controller. The Hitachi Virtual Storage Platform G350, G370, G700, G900 and Virtual Storage Platform F350, F370, F700, F900 models allow a defective controller to be replaced.
VSP G350, G370, G700, G900 models support a variety of drives, including HDDs, SSDs for the G350 and G370. The G700 and G900 provide additional support for FMD HD drives including the second-generation Hitachi Accelerated Flash (HAF) flash module drives (FMD DC2) that are the foundation of the VSP F350, F370, F700, F900 models. The FMD DC2 drives deliver improved response times, effective flash capacity, and return on investment. The VSP G700 and VSP G900 combine FMD DC2 flash with inline compression and Hitachi Dynamic Tiering active flash for improved responsiveness and efficiency, making it simple to move to all-flash gradually over time. The storage systems allow defective drives to be hot swapped without interrupting data availability. A hot spare drive can be configured to replace a failed drive automatically, securing the fault-tolerant integrity of the logical drive. Self-contained, hardware-based RAID logical drives provide maximum performance in compact external enclosures.
All models are compatible with most industry-standard, 4-post EIA 19-inch racks with square mounting holes. The storage system can be factory-configured and shipped in a Hitachi V2 Universal Rack (600 x 1200 mm) or shipped without a rack for installation into an existing compatible rack. The Hitachi rack comes with either two or four power distribution units (PDUs), depending on the PDU model selected.
The VSP F350, F370, F700, F900 all-flash arrays bring together all-flash storage and the simplicity of built-in automation software with the proven resiliency and performance of Hitachi VSP technology. The all-flash arrays offers up to 2.4 million IOPS to meet the most demanding application requirements. The all-flash arrays leverage the FMD DC2 second-generation flash module drives, which deliver twice the capacity per tray over previous-generation flash module drives, resulting in a smaller data-center footprint and lower maximum-performance cost. Fast inline data compression with an ASIC engine reduces space with no performance penalty.
Easy-to-use replication management is included with the all-flash arrays with optional synchronous and asynchronous replication available for complete data protection. The all-flash arrays range in storage capacity from 1.4 PB (raw) up to 8.7 PB effective flash capacity and provide an all-flash solution that works seamlessly with other Hitachi infrastructure products through common management software and rich automation tools.
Hitachi Virtual Storage Platform G350, G370, G700, G900 and Virtual Storage Platform F350, F370, F700, F900 models work with a service processor (SVP). The SVP provides out‑of‑band configuration and management of the storage system and collects performance data for key components to enable diagnostic testing and analysis.
The SVP is available as a physical device provided by Hitachi Vantara or as a software application:
- The physical SVP is a 1U management server that runs Windows Embedded Standard 10.
- The SVP software application is installed on a customer-supplied server and runs on a customer-supplied version of Windows.
