IntelliCare Cloud Analytics

Save time on storage administration and maximize the uptime and efficiency of your Western Digital Tegile storage arrays with IntelliCare™.

Driven by cloud-based analytics and backed by a team of storage experts, IntelliCare enables you to quickly and easily monitor the health, performance and usage of all your Western Digital Tegile storage arrays, predict future requirements, and detect problems before they develop into serious issues.

IntelliFlash Architecture

Western Digital Tegile’s flash storage arrays are powered by IntelliFlash. This fast, flexible software architecture is designed to leverage different grades of storage media—hard disk, high-performance flash, high-density flash, etc.—in a single storage array

IntelliFlash understands the inherent characteristics of different storage media and intelligently manages the placement of data to deliver optimal performance (speed and latency) with the best possible economics. It also includes advanced data services, multiprotocol support, and flexible management capabilities, enabling you to significantly shrink your storage footprint, maximize uptime, consolidate workloads, and simplify storage administration.

Data Security

Keep your data safe and secure. Data security is provided using 256-bit AES encryption of data at rest. IntelliFlash delivers in-line encryption of data on SSDs and hard disk drives with unnoticeable impact on performance. Key management required for encryption is performed natively in the system without user intervention.

feat

Built-in Business Continuity

Take instantaneous point-in-time snapshots that are both VM-aware and application-consistent. For disaster recovery, replicate snapshots to a remote site. Replication transmits only changed data to reduce traffic over the WAN.

feat

NAS and SAN from the Same Array

Enjoy the flexibility protocol of choice in how your storage is connected to your servers. No more silos of storage in your data center. FC, iSCSI, NFS, CIFS SMB 3.0 are all supported.

feat

Up to 10:1 Data Reduction

In-line compression and de-duplication on SSD and hard disk throughout array. This helps significantly reduce storage acquisition and operational cost. Redundant operating system images in a virtual server platform are reduced to a single instance stored in flash. Hundreds or thousands of persistent VDI instances are shrunk down to one single boot image that can launch in seconds.

feat

Storage Simplified

Single-click provisioning through application-optimized aware templates and integrated backup and replication without complex backend software. Monitor your storage infrastructure with your own Management Tool using SNMP.

feat

Purpose-built for Virtualization

One-click virtual machine optimized storage creation enables hundreds of virtual machines and desktops to be deployed in minutes, not hours. VM-aware management tools let storage be provisioned, monitored and managed in virtual machine granularity – LUNs, file systems and RAID groups are a thing of the past for virtualization administrators.

Accelerating Reads & Writes with IntelliFlash:

Western Digital Tegile Intelligent Flash Arrays enable enterprises to strike the perfect balance between performance and capacity. Each array is powered by the IntelliFlash™ software architecture. IntelliFlash gives you the flexibility to use all flash or a mixture of flash and disk. The software architecture intelligently manages the different storage media to deliver optimized performance and capacity.

This technology brief explains how IntelliFlash accelerates the read and write process within a Western Digital Tegile hybrid array.

Performance & Capacity Layers

Within each Western Digital Tegile array, there is a performance storage layer and a capacity storage layer. In the performance layer, there's a combination of DRAM and flash. This gives you the high performance and low latency you need for your virtual server, VDI, messaging, collaboration, and database applications. The capacity layer takes full advantage of the evolution in media densities. It accommodates spinning hard disk drives today and is designed to be flexible enough to accommodate emerging storage media as they become available.

Performance & Capacity Layers

Dual-Controller Architecture

All Western Digital Tegile arrays come with dual controllers. Multiple storage pools can be created within the Western Digital Tegile array. These storage pools can be all-flash (FlashVols) or a combination of flash and hard disk. A storage pool at any given point in time is associated with one of the two controllers. Both controllers can be used simultaneously by associating different pools to each controller.

In the event of a controller failure, or for live software upgrades, the associated pools can be failed-over transparently—with no perceived outage.

Dual-Controller Architecture

Accelerating Writes

All writes to the Western Digital Tegile array are synchronous. The moment the data is received, it's saved to a persistent "Write Cache" in flash and an acknowledgement is sent back to the host. Round trip, that whole process takes a millisecond or less.

Accelerating Writes

Metadata Acceleration

To optimize the IO path, IntelliFlash dedicates a portion of the performance layer exclusively for metadata. This includes block pointers, deduplication signatures, compression type, and the like. All of the metadata is organized, aggregated, and remains in this dedicated, persistent section within performance layer. This performance- optimization technique stands in stark contrast to traditional storage systems, which intersperse metadata with the rest of the data on disk. Over time, as data inevitably gets modified, deleted, and rewritten, the metadata becomes very fragmented, which negatively impacts performance.

Metadata Acceleration

Data Reduction

IntelliFlash also performs inline compression and deduplication. These data reduction techniques can not only shrink your storage footprint by up to 90 percent, they also act as performance multipliers by freeing up space in the performance layer for faster reads and writes.

Each data block is compressed and redundant data blocks are removed before they are written to disk. You can choose the compression rate and turn on/off deduplication at the volume level to strike the perfect balance between speed and capacity.

Data Reduction

The resulting unique data blocks are coalesced and streamed sequentially to the capacity layer. After that happens, the data is removed from the "Write Cache" and the process is complete.

Data Reduction

Accelerating Reads

Intelligent caching algorithms keep the most frequently accessed data in the Read Cache, which resides on DRAM and flash. These caching algorithms are optimized for various I/O patterns and dynamically adapt to differing media latencies across multiple levels of cache.

There are two levels of Read Cache in a Western Digital Tegile array. Both are self-tuning. The first level is the primary DRAM cache. This is smaller and faster. The second level resides on flash.

The array proactively fetches and populates the read cache with the hottest data. This all happens dynamically — in real time using intelligent, pre-fetch algorithms — without user intervention.

In most customer cases, the cache-hit ratio is well over 90%. That means that most read requests are satisfied from DRAM and flash.

Accelerating Reads

Western Digital Tegile Intelligent Flash Arrays use IntelliFlash to intelligently manage different types of media to deliver incredibly fast performance while also maximizing capacity and keeping your storage costs in check.

Flash Storage Arrays - All-Flash vs Hybrid

What is the deal with Flash?

Flash is dramatically faster and uses less energy and space than traditional disk-based storage and is perfect for those applications that require performance. However disk-based storage isn't going away just yet and is still great for those applications where low-cost and high capacity trumps performance.

SSD

All-Flash can be expensive but in applications where performance and latency are critical, All-Flash is the way to go.

SSD + HDD

A hybrid flash system that mixes flash with low cost disks is ideal for most enterprise workloads.

HDD

Traditional disk-based storage is low cost but has high latency, low IOPs and uses more energy and rackspace as capacity grows.

What is the deal with latency?

Really important when you need fast reliable performance.
