Last week we expanded our enterprise storage coverage with flash arrays and today the coverage continues with Tegile's announcement of the T3600 and T3700. To bring everyone up to the speed, let's start with a brief introduction of the company. Tegile was founded in 2009 by Rohit Kshetrapal, Rajesh Nair, Justin Cheen and Alok Agrawal and operated in stealth mode until 2012. The founders share a history at Perfigo, which was a developer of packaged network access control solutions that was acquired by Cisco in 2004. As a result Tegile's expertise lies in the networking and connectivity aspect of the array, and hence Tegile provides both hybrid and all-flash arrays.

SanDisk and Western Digital (i.e. HGST) are strategic investors in the company, which guarantees Tegile access to the latest SSDs at competitive prices. Currently all Tegile's arrays use SAS SSDs, for which SanDisk and HGST both have extensive lineups, but as the industry moves towards PCIe Tegile will be making the transition as well. Tegile is already evaluating some of Fusion-io's PCIe SSDs now that the company is under SanDisk, but there are no finalized plans for a product yet.

The T3600 and T3700 are additions to Tegile's all-flash arrays and bring smaller capacity points to the lineup. The existing T3800 started at 48TB raw, but Tegile told me that many customers were looking for something around 10-20TB in capacity and the T3800 was too beefy (read: expensive) for that. The T3600 and T3700 have 9.6TB and 24TB of raw flash respectively, which can be extended by using expansion shelves.

The expansion shelves are basically just a bunch of drives that connect to the array and use its logic, but it should be kept in mind that the shelves are their own units and thus eat up rack space. 2U and 4U expansions are available with the T3600 and T3700 having support for either four 2U (ESF-10/25/50) or two 4U (ESF-145) expansions. The maximum effective capacity is achieved with two ESF-145 expansions that are 144TB each and a 5x multiplier from compression and de-duplication, which Tegile claims is the typical increase in usable capacity. Obviously, the actual multiplier depends on the stored data and some workloads are inherently more compressible than others, so the 5x multiplier is merely an ideal guideline.

The T3400 is different from the rest in the sense that it supports the HDD-based 72TB ES4000 expansion shelf, whereas the other T3000 series models don't. The reason lies in the architecture as the T3400 utilizes a pool of very low latency SSDs (likely SLC-based) that are used for metadata handling. The way Tegile handles metadata is actually one of its core advantages because Tegile stores the host and meta data separately, which is essential for efficient data de-duplication and also prevents the metadata from fragmenting. The usage of lower latency SSDs in the T3400 makes sense because all the meta data IOs need to be offloaded from the HDDs, but since that is not a problem with the rest of the T3000 lineup, high density eMLC SSDs are used in other models. All drives in the array are Self Encrypting Drives (SEDs) with AES-256 support.

On the connectivity side, all T3000 series models have 14 1Gbps Ethernet ports with two of them dedicated to management. Additional connectivity options include dual-port 4/8 Fibre-Channel, 10Gbps Ethernet and quad-port 1Gbps Ethernet. Protocol support includes iSCSI, FC, NFS, CIFS and SMB protocols.

Along with the T3600 and T3700 releases, Tegile has updated its IntelliFlash OS to 3.0. The provisioning process has been streamlined and the provisioning profiles have been enhanced. The idea behind the provisioning profiles is to give IT administrators an easy way to set up provisioning based on the workload because not all IT administrators necessarily understand the complex storage architectures and what is the optimal provisioning for their workload.

Tegile is also releasing cloud-based IntelliCare customer support, which automatically collects various data points from the array and sends them to Tegile's servers for analysis. The analysis allows Tegile to inform the customer about any potential component failures or other issues, and what's interesting is that Tegile customers can view metrics of another customer's Tegile array. Hence IT administrators can compare their array against other Tegile arrays in the wild and can see if there are any settings that could be toggled for more optimized performance.

The T3600 and T3700 are both available now and start at $220,000 (~$23/GB) and $300,000 ($12.50/GB) respectively.

    LOL this is a pathetic attempt at advertising.

    And $300K for 24TB of storage?! LOL I can buy an all-flash array from one of the big guys for less and not be worried about reliability/support.
  • mmrezaie - Tuesday, November 4, 2014 - link

    I agree with the first sentence, but it doesn't mean they don't have support or are not reliable. Unfortunately Anandtech is getting full of native advertisement although sometimes Anand's own hardware insights were really good.

    Let me put it this way - you have a $250K storage budget. Do you buy EMC, Netapp, HP, Dell, Hitachi for less or take a flyer on this thing (keep in mind your job/career is tied to this stuff)?
  • ialbulushi - Tuesday, November 4, 2014 - link

    EMC XtremeIO is within the same ballpark price/GB, and so is Pure storage. I've been keeping an eye on Tegile, they've been growing pretty fast and couple of friends who got test boxes like it a lot (they got their Hybrid boxes though, not the all flash). I get the comment about career, but lets be honest every time someone buys an array they will have half their IT staff complain about the purchase and how they got the wrong box.

    The big storage companies have been complacent, these new entries into the market (like Pure Storage) are shaking things up nicely and finally giving us some innovation.
  • Black Obsidian - Wednesday, November 5, 2014 - link

    DukeN, virtually none of the companies you refer to have a meaningful play in the all-flash space, EMC's scramble to buy and integrate someone who does notwithstanding.

    You can certainly still buy one of their products if you prioritize "playing it safe" and don't mind the outdated interface, architecture, and performance levels. I personally prioritize the most efficient use of my company's dollars, and when it comes to using SSDs intelligently, it's either HP or one of the new guys (Pure, Tegile, Nimble, etc.).

    Black Obsidian beat me to it: Your's is a blatantly ignorant perspective on evaluating enterprise storage. NTAP and EMC continue to lose market share (due mostly to customers refusing to pay legacy software licensing and support models), Dell goes private so they don't have to explain their shrinking market share quarter after quarter, while HP continues to wonder what to do with 3 completely separate storage offerings that can't be integrated?

    You've essentially provided a list of dysfunctional dinosaurs whose only response to innovation is to acquire. I suppose you're still using the old adage that "No one ever lost their job for buying IBM" too? I know a few XIV and SVC users who would surely disagree.

    A few of these flash start ups offer some compelling solutions that are both fast and cheap. If you're not considering them because they don't have expensive EMC or NetApp bezels, you're not really doing your job, let alone playing it "safe".

    What makes you think this is an advertisement? I don't see where I've particularly praised Tegile. We've been reporting product launches for a long time and it's not always possible to have a detailed analysis in the launch article given the tight deadlines and complexity of the devices.
  • Beelzebubba9 - Tuesday, November 4, 2014 - link

    I've used Tegile's systems in the field and have also been generally impressed with them. I certainly would consider their hybrid solutions over a VNX 5400 or Mid range NetApp unit if random IO and multi-protocol support were important for the deployment.

    I feel like the OP has never really been in charge of an enterprise SAN/NAS purchase process. Nor does he seem to understand those are list prices, not street.
  • cygnus1 - Tuesday, November 4, 2014 - link

    yeah, you won't get an all flash array with the same protocol support for that price
  • cygnus1 - Tuesday, November 4, 2014 - link

    and you're also not accounting for the dedupe and other features you will priced out of if you look elsewhere
