Hybrid Storage Pool Model for Sun Storage 7000 Unified Storage System Family
In his continuing series, Chris Evans of The Storage Architect blog took another in-depth look at the Amber Road platform. In this post, he turned his sights on the disk components of the hardware, specifically looking at the use of flash (SSD) drives and ZFS to produce a commodity storage device.
Chris began with a primer on ZFS, sharing the basic concepts and bringing the filesystem features to life and what they bring to the Amber Road platform. He also provided an overview of the Unified Storage System's cache architecture, noting the adaptive replacement cache and the ZFS intent log, and the fault tolerance and performance these features offer the 7000 series.
Chris picked up the core difference between Amber Road and traditional storage devices. "In a typical general storage array there will be LUNs presented to hosts which are very active, some moderately active and some totally inactive." He noted that Amber Road provides and alternative to the traditional "Long Tail" model, highlighting "fronting disk access with SSD ensures that high performance is dynamically provided to LUNs as it is needed."
Overall, Chris is positive about the architectural choices made for Amber Road and was unable to find fault via his evaluation. "I can say that in the testing I performed, the array coped easily with the workload I threw at it," he stated.
Chris' next post will be an in-depth look at the analytics provided by Amber Road and how it allows detailed device reporting.

Sun Storage 7410 Unified Storage System
Network World's Logan Harbaugh tested the Sun Storage 7410 Unified Storage System, giving it a rating of 3.75 out of 5.0. In his review, Logan focused his evaluation on the system's architecture, performance and business analytics, and noted that the unit "is certainly a high-performance offering."
Logan highlighted the test system's configurations (noting the read- and write-enabled SSDs, Quad-core Opteron-based 7410 controllers, SATA drives and J4400 drive shelves) leading to a discussion of the 7410's clustering capabilities.
The reviewer next turned his focus to the 7410's performance. He employed IOmeter, configured with four sets of application-based workloads to simulate storage traffic. Logan noted, "Performance of the single controller system, as far as our limited test bed could verify, was excellent."
Logan also took a look at management and reporting capabilities. He commented, "the business analytics section of the GUI-based admin interface contains very useful monitoring tools, with the ability to drill down to specific interfaces, network or storage protocols."
He went on to describe that reports are available in a very wide variety of formats, with many variations. Further, he noted that reports are available for disk IO, overall storage utilization, and historical data is available and the amount of storage used for logging can be adjusted to keep data for longer or shorter periods of time.
Logan concluded, that the system is "clearly positioned - in terms of price, feature set and performance capacity - to go toe-to-toe with big systems from NetApp and EMC that are designed to support dozens of connected servers simultaneously." And regarding performance, Logan reiterated that "while we could not push the box to its capacity, we were impressed by what it could handle in our test environment."
The full review is here.

Sun Storage 7210 Unified Storage System
Chris Evans of "The Storage Architect" blog posted part one in a series of reviews of the Sun Storage 7000 Unified Storage System, saying, "Over the last month, I've been reviewing the 7210 array (the mid-range offering) and as an early product release, I can say I like it."
Chris framed the review against the increasing trend of centralized storage in the datacenter, and said the most unique part of the system is Sun's use of "solid state to drive performance out of the commodity SATA drives in the array."
As part of an introduction to the product line, Chris discussed the use of highly scalable storage solutions built on commodity hardware and open software components. Compared to other vendors, Chris noted that Sun is "taking the approach of offering all current and future software features as part of the standard hardware cost. This extends to the lifetime of the technology, so as new software features are made available in future releases, the customer can simply upgrade the USS and take advantage of them at no extra cost."
Overall the reviewer was quite positive about the Sun Storage 7210, noting that Sun has differentiated its offering from other "server as a storage array" solutions. "From a hardware perspective, what's more interesting is the use of solid state to drive performance out of the commodity SATA drives in the array," he stated.
Chris concluded by noting in his next post, he'll be examining ZFS in more depth.
I am eagerly looking forward to the rest of the series...

Sun Storage 7410 Unified Storage System
IT Pro's Dave Mitchell reviewed the Sun Storage 7410 and gave the unit 5 out of 6 stars and as well as an Editor's Choice award. Dave stated, "Sun delivers a unique network storage solution with more standard features than the rest and no hidden charges."
The reviewer examined installation, configuration and noted some observations about the quad-core 2300 Opteron architecture, "this server is quite unique as it can accept an extra mezzanine tray with two more Opteron sockets making it the only 2U quad-socket AMD server on the market."
Further, Dave discussed the file system, protocol support for shares and performance. "We found real world speeds particularly good as copying a 2.52GB video clip to and from an iSCSI target returned read and write speeds of 89MB/sec and 72MB/sec. Using the FileZilla client showed FTP speeds to be even faster with it reporting impressive read and write rates of 103MB/sec and 92MB/sec. CIFS usually puts the brakes on speed but even here we saw file copies returning rates of 66MB/sec and 59MB/sec," he noted.
Overall, Dave stated, "Add up the standard features on the Sun Storage 7410 plus its hardware specification and it looks good value - especially when compared with much of the competition at this level of the market. Furthermore, along with NAS and IP SAN support, it offers a massive expansion potential and good performance across a range of protocols."

Real-time analysis screenshot of the Amber Road storage system
|The folks at ILM Informatique
has published a very detailed review of the Sun Storage 7110 Unified Storage
System. This Amber Road review is available in English here,
and in French here.
After providing the specific of the unit they received, ILM Informatique goes over the installation, functionalities, performance as well as additional functionalities they would like to see.
Their final conclusion:
"The Sun Storage 7110 server we tested made the brilliant demonstration of its velocity and was easy to configure. Solaris and its ZFS filesystem using the full power of the hardware. At $10,995, you will not regret your investment. It will be very difficult to find the bottleneck of the server moreover it will keep your files safe.
We recommend this model for a group of 20 to 200 users."

Real-time analysis screenshot of the Amber Road storage system
Infoworld's Paul Venezia reviewed the Sun Storage 7210 Unified Storage System (Amber Road) and accompanying FISHworks management platform, rating it a stellar 9.2 out of 10 and noting, "The Sun Storage 7210 Unified Storage System's combination of 48 drives, SSD log storage, broad protocol support, ZFS, and amazing GUI make for one great filer."
Paul took a comprehensive look at the unit's management features, including its real-time monitoring and analytics capabilities. After only a few minutes of use with FISHworks he noted, "I was smitten. It's very attractive and very accessible. In fact, it may be the most complete filer interface I've ever seen, blowing the doors off Network Appliance's Web-based manager." Paul drilled down into the GUI, highlighting its instant feedback on load and throughput as well as the worksheets ability to provide easy at-a-glance status reports.
Turning his attention to the hardware, Paul configured a storage pool and tested performance via a number of access protocols. For NFS access via Linux, he highlighted that creation of a 10GB file performed at near wire-rate over a gigabit NIC. Paul also noted the solid performance of sequential reads and writes to NFS3, NFS4, iSCSI and CIFS, calling out the 55 to 60MBps throughput while under load. "Again, this is very close to wire-rate speeds," he stated.
Overall, Paul was very positive about his experience with the 7210 concluding, "The market for multilingual filers has plenty of players, from NetApp to Adaptec, but in terms of bang for the buck, Sun's 7210 is in rare territory. Regardless of price, son of Thumper is a uniquely complete representation of what a filer should be."

Sun Storage 7110 Unified Storage System
|The January issue of PC Pro has
a very positive Amber Road review.
The reviewer, Dave Mitchell, tested an entry-level Sun Storage 7110 Unified Storage
System and he was quited impressed, calling it "something special."
Dave examined installation, performance and key features such as DTrace and the bevy of supported protocols. "The 7110 proved quick, with Iometer reporting a speedy 112MB/sec raw read throughput for one iSCSI target," he noted. Further, "real-world speeds for iSCSI were good, as copying a 2.52GB video returned read and write speeds of 89MB/sec and 76MB/sec. FTP was even faster with the FileZilla client reporting read and write speeds of 99MB/sec and 86MB/sec using the same test file."
In closing, the reviewer commented, "The 7110 delivers a complete network storage solution with no hidden catches. Both NAS and IP SAN are supported, performance is very good, and Sun won't be beaten on value."
PC Pro's final verdict: "The 7110 is the storage host with the most since it offers NAS and IP SAN support - all as standard."
Of course, the product got "PC Pro Recommended" status.

Logan Harbaugh posted a review
under "Storage Adviser" column, discussing the various features of ZFS
present in the recently announced Sun
Storage 7000 Unified Storage Systems.
Logan said the "most alluring features are the file system and the analytics made available through SNIA-standard RPC calls, using the DTrace fault tracing system included in OpenSolaris."
|Of the specific features, Logan
called out the Hybrid
Storage Pools, "which integrate
DRAM, read-optimized SSDs, write-optimized SSDs, and regular disk into
a seamless whole." The use of DTrace in the system "make all sorts of performance data
available," which Logan said will also allow for very granular
optimization. Logan then listed several features such as the clustering
capabilities of ZFS, data services, support for a variety of protocols,
storage system as providing the system "a lot of potential."
Overall, Logan commented, "the Sun hardware should provide good capabilities at a good price. But the best part is that the software magic is also available through the open source OpenSolaris and ZFS, as long as the hardware you choose has all the parts necessary to fully utilize the ZFS capabilities."

on the Sun
Storage 7000 Unified Storage Systems, InfoWorld's Paul Venezia
discussed what the new products represent to the storage market. Paul
said, "what the 7210 and its brethren
provide is an elegant storage framework that includes the best-of-breed
ZFS file system coupled with read- and write-biased SSDs, support for
CIFS, iSCSI, NDMP, FTP, (and others) driven by a truly breathtaking interface."
Paul discussed some of the product features, such as how the SSDs vary among the product line, and cited Sun engineers who "claimed that the addition of the read-biased SSD caching in conjunction with ZFS' predictive caching algorithms means that 7,200-rpm SATA drives perform just as well, if not better than 10K SAS drives." Paul went on to note that he has been "a fan of ZFS for some time now, and it's only getting better and better."
Paul also discussed the evolution of storage, and the challenges faced from storing large amounts of data, backing up data, and the user interface with searching through the data. Against these challenges, "the new capabilities offered with products like the Sun 7000-series storage appliances are paving the way for new takes on old ideas, such as video-on-demand."
Paul is soon going to publish a full product review but for now, "it's really impressive to be able to quickly pull up real-time user- and file-level throughput statistics complete with live graphs."
|He concluded the post with a quote from a character from The Simpsons, saying, "In the immortal words of Kent Brockman, I, for one, welcome our new storage overlords."|
