Hard drives continue to remain the storage medium of choice for applications where capacity and cost factors outweigh performance requirements. Vendors have also realized that enterprise hard drives are an overkill for some applications, but the recen…
In the current NAS market, it is downright impossible to talk of ARM and high performance together. The most powerful ARM-based NAS units have been based on Marvell’s ARMADA processors. They usually come with dual gigabit network links and typically target the SOHO and low-end SMB market. Intel’s offerings have had a virtual monopoly in the other tiers of the market. Synology is set to change all that with their latest offering – the DS2015xs with native 10G capabilities.
The DS2015xs is 8-bay NAS unit presented as a step-up from the DS1815+. While the DS1815+ can expand up to a total of 18 bays with two DX513 expansion chassis, the DS2015xs is compatible with the 12-bay DX1215 expander (for a total of 20 bays). The main step-up from the DS1815+ is the presence of two built-in 10G SFP+ copper links.
Claimed performance numbers include transfer speeds of up to 2000 MBps and 59K sequenital IOPS.
The SoC at the heart of the DS2015xs is the AL-514 from Annapurna Labs, an Israeli startup that is still in stealth mode. The company has declined to speak to the media as of now. However, tracing some coverage of Israeli VC firms reveals that Annapurna Labs was founded in 2011 with the intent of bringing ARM-based communication processors to the market. Datasheets of SoCs from Annapurna Labs are not currently available to the public, but Synology was kind enough to divulge the following details (which, I suspect, can be gleaned via SSH access to the DS2015xs):
Beyond these, details are scarce. We hope Annapurna Labs comes out of stealth mode soon and supplies us with more details. We might possibly be able to gather more information about the platform once we get the DS2015xs in hand.
Moving on to the relevance of the AL-514 for the ARM ecosystem, it is clear that at least Synology considers it to be a worthy competitor to Intel’s Rangeley. The DS2015xs is being positioned as a clear step-up from the Rangeley-based DS1815+. That said, the fact is that A15 is a 32-bit processor, and it is not entirely suitable (despite the LPAE extensions) for high-performance servers. ARM has since moved on to ARMv8 processors (true 64-bit) for both the smartphone and the server / communication infrastructure market.

UPDATE
Annapurna Labs has sent across the following information to the media through Synology, which we are quoting verbatim:
END OF UPDATE

In other related news, Synology is also launching the DS3615xs, a native 12-bay desktop form factor solution (expandable to 36 bays with support for two DX1215 expanders). It is a straight-up upgrade to the previous-generation DS3612xs which used a Sandy Bridge-based Core i3-2100. The DS3615xs uses the Haswell Core i3-4130. It comes with four gigabit links, but also has support for a PCIe expansion card (to potentially add 10G capabilities). Like the previous generation xs-units, it comes with ECC RAM (4GB DDR3 by default, expandable to 32GB). Pricing and release date in the Americas for the DS3615xs is not yet available.
The DX1215 is a 12-bay expansion unit for select Synology DiskStation models. Unlike the eSATA-based DX513, the DX1215 connects to the main unit using Infiniband. Further details are available here.
The DS2015xs will retail for $1400 – a price that really makes 10G affordable, while undercutting the introductory pricing of the previous generation xs units significantly. We have to admit that the xs positioning of the unit was initially very surprising. After all, the Cortex A15 really can’t stand up to the Core i3 (on which the previous generation xs units have been based) in terms of raw CPU performance. There is no support for ECC RAM either. Synology clarified that the CPU performance would definitely not match up. However, the presence of communication and storage accelerators – particularly, natively integrated 10G capabilities, RAID acceleration and hardware-assisted encryption – enable the DS2015xs to support bandwidths that have typically not been reached at this price point.
While the Annapurna AL-514 SoC seems more like a stop-gap solution for this market segment (particularly when true 64b ARM solutions are starting to make an appearance), consumers are fortunately shielded by Synology’s DiskStation Manager (DSM) OS. The operating system manages to isolate the user experience with various NAS aspects from the underlying platform architecture. The end-user experience is the same, regardless of whether the NAS being used is based on ARM or x86.
On the whole, Synology seems to have hit a home run with the price to performance ratio in the DS2015xs. We hope to soon have a unit in hand to test out how it performs with our standardized lab environment. We would also like to hear from readers on what sort of applications they are running on their Synology NAS units. This would help us determine how much of a performance difference there is between, say, the DS1815+ and the DS2015xs, for applications that matter to end users.

We have seen this story play out before. Western Digital delineates the hard drive market with a product aimed at a particular niche and Seagate comes in a few months later with a new product line aiming to one-up Western Digital’s introduction. The specifications for the Seagate product are a little bit better (SKUs with higher capacity, slightly better performance etc.) – after all, it never pays to be a me-too product in the market without offering something extra to the end users. In the same vein, Seagate is introducing the Enterprise NAS HDD today to go against Western Digital’s Red Pro
Similar to the WD Red Pro, the Enterprise NAS HDD is targeted at prosumers / SMB / SME tower and rackmount form factor systems with 8-16 bays (though nothing prevents them from being used in systems with a lower bay count). They are standard 7200 RPM drives with the right balance of features imported from both the NAS HDD as well as Enterprise Capacity lineups.
The key points of differentiation over the WD Red Pro are listed below:
Other aspects (such as warranty and URE ratings) are mostly similar. Out of the four points above, the bundled data recovery service is the most interesting. Seagate introduced their data rescue and hardware replacement services last year. In pursuit of differentiation and better integration of this offering with the rest of the company products, the Enterprise NAS HDDs come with this service bundled in the cost. In case of any failure (environmental, accidental or even human error), Seagate handles data recovery as well as replacement of faulty drives (within the warranty limitations). Failed RAID arrays are no exception. With the Enterprise NAS HDDs, this DRS is valid for 3 years starting with the date of purchase. Since the risk of data loss and recovery is borne by Seagate for a reasonable premium, both end-users and resellers are bound to be happy.
Coming back to the rest of the HDD products from Seagate, the table below compares their specifications and differentiating aspects.
Even though it is not specifically mentioned, Seagate indicated that the Enterprise NAS HDDs are designed for workloads up to 180 TB/yr.
For the launch of the Enterprise NAS HDDs, Seagate has teamed up with QNAP. They are also running two webinars to cover any questions that SMB / SME IT decision makers may have regarding the new products.
Pricing information is not available yet, but Seagate indicated that they would be competitive with the WD Red Pro at similar capacity points (with a reasonable premium for the additional data recovery service).
