Hybrid solutions may be the way to go for a lot of enterprises seeking to understand how flash can best be used to improve overall system performance. At issue here though is whether any such moves will require a re-architecting of existing applications and systems to take advantage of the performance promised by such systems, and whether it makes sense at all to go the middle road of hybrid systems as opposed to deploy all-flash systems within the overall storage infrastructure of the organization and set up tiering strategy assigning specific applications to particular storage based on workload requirements.
Tegile’s first and all flash (until now) array was the HA2800 which featured 4.4TB of raw flash. It was used primarily for caching and, oddly enough, scaling out was by adding HDDs rather than flash – why would they do that? The new T3800 is suited for OLTP and data analytics, and this time, scaling out is done with SSDs – the company must have discovered the logic behind staying with all flash even when scaling out. Tegile markets the T3800 as capable of 1.6PB of usable capacity with 5-1 data reduction using its inline deduplication and inline compression.
I’m still waiting for a response from Tegile with regards to availability and support in Asia. Keep you posted.
Tegile began selling its flash systems in 2012. It claims more than 500 customers, mostly for its hybrid arrays. Its lone flash array, until now, was the HA2800, which supports only 4.4 TB of raw flash. The flash in the HA2800 is used for caching rather than a storage tier, and the system scales out by adding hard disk drive (HDD) shelves rather than flash. The new T3800 is a storage tier for low-latency, business-critical applications, such as OLTP or data analytics. It scales by adding solid-state drives (SSDs) rather than HDDs, and Tegile said it can store 1.6 PB of usable capacity, minimum raw capacity is 48TB, with 5-1 data reduction from its inline deduplication and inline compression.
The T3800 comes in a 2U chassis and uses Intel Xeon E5-2450 processors first launched in Q2 2012. Mark Evans, a storage consultant in the US, writes that “Moving past the speeds and feeds for a moment, probably the more interesting news in this release is the price point Tegile has achieved. Their effective $/GB price is quoted as $1.1/GB – remember “effective” means after data reduction so that’s a raw $5.5/GB, which is extremely competitive.”
He believes that Tegile’s Intelliflash range is going after the 15K FC drive market, currently led by EMC and NetApp. Certainly a hybrid device that supports block (iSCSI & Fibre Channel) and file (NFS, SMB3) with attractive price-performance will be an attractive solution for budget-conscious customers. But neither EMC nor NetApp are standing still. Both vendors are pushing forward their hybrid solutions as well, and certainly their customers in Asia will likely stay with known names as opposed to startups that still need to prove themselves particularly in post-sales or after-market support.
then what we have is a system that isn’t targeted at the all-flash market but at taking out the tier 1 competition based on 15K FC drives. Layer in the new T3400 and you start to see how things have become harder for the likes of EMC and NetApp with their legacy mid-range platforms.
Tegile Systems, Inc. introduced the two entries into its product line that balance data management, performance and economics - the T3400, which provides a flexible amount of high-density SSDs and metadata-accelerated high-density HDD; and the T3800, the company's newest all-flash array that eliminates the top three customer challenges associated with offerings from other all-flash vendors.
The T3800 features high-density enterprise flash SSDs designed to support mission-critical applications that require high performance at low latency for extended periods of time. Issues that customers typically have with all-flash storage systems are expensive price per gigabyte, short-lived components and lack of density comparative to HDD systems have been rendered obsolete with the introduction of the T3800. In a typical mixed-application environment, Tegile achieves a 5X data reduction to realize a $1/GB street price. The array's 10PB per drive endurance allows Tegile to offer a seven-year warranty without the need for periodic wholesale system upgrades. At 55 effective TB per U, the T3800 goes beyond traditional HDD-based array density.
Tegile's previous hybrid array had approximately 5% of its capacity in flash. With the introduction of the T3400, Tegile now offers a storage architecture featuring half of its capacity in flash SSDs and half in HDDs, resulting in a 20X increase in flash density over previous models. The T3400 base configuration includes 22TB of high-density flash storage and a 2.2TB metadata acceleration engine. Optional upgrades include HDD expansion shelves with either 24 or 72 raw terabytes; or SSD expansion shelves with either 48 or 144 raw terabytes.
"Tegile might be known as a hybrid storage company, but the extensibility of its architecture makes offering a leadership-class, all-flash array very simple relative to trying to add flash to a legacy architecture," said James Bagley, senior analyst at SSG-NOW. "Overcoming hesitancy of customers regarding pure-flash installations while at the same time understanding enterprises' capacity-centric requirements with hybrid offerings, places Tegile in an enviable position. No other storage system is so well balanced in leadership data management, performance and economics than Tegile's."
Tegile's latest enterprise arrays are built on the company's third-generation IntelliFlash technology that provides the performance, capacity and reliability that organizations desire at a relatively low cost. Data reduction technology provides a usable capacity that's greater than the arrays' raw capacity. A no-single-point-of-failure architecture, automated snapshot and thin replication features make them more reliable than competitive alternatives.
Like its previous flash-driven storage arrays, T3400 and T3800 feature four eight-core Xeon processors, significant memory, sizable read and write caches using flash, multiple networking interfaces, dual power supplies and hot disk spares to provide high performance at low cost.
The systems' software simplifies administration and optimizes storage for various applications, including virtualization, file services and databases. All-inclusive pricing for features such as auto-snapshot, auto-replication, near-instant recovery, on or offsite failover, and virtualization management provides simplified software licensing at a fraction of the cost of storage incumbents.
All Tegile products, including the T3400 and T3800, are available through consumption-based leasing, Tegile's Agility Pricing Program, paying only for the amount of data space utilized - as low as 20.6 cents/GB/month. The program was designed for cost-conscious customers who are interested in leveraging cloud economics but who are unwilling or unable to relinquish control of their data to third-party providers at pricing competitive to Amazon S3.
"We're excited about the opportunity to provide even more flash options to our customers with the introduction of the T3400 and T3800," said Rob Commins, VP marketing, Tegile. "Whether it's a balanced approach of high performance with high capacity of a hybrid array or sustained high performance with low latency of applications best served with flash, we have developed a range of superior product offerings that can satisfy any and all of these requirements without breaking the bank."
The T3400 and T3800 are available through the company's reseller partners. All arrays come bundled with IntelliFlash flash optimization software and a data management suite including snapshots, remote replication and VM-aware management tools.
