NetApp FAS2240-2 evaluate (FAS2200 series)

April 2nd, 2014 by using StorageReview business Lab

The NetApp FAS2240-2 is a unified storage platform for each SAN and NAS that elements 24 bays of high-efficiency storage for a optimum of 28.8TB of uncooked capacity, which could scale to 509TB using enlargement disk shelves. Engineered basically for midsized firms with dispensed environments, the FAS2240-2 supports each SSDs and high-efficiency 10K HDDs. FAS2240-2 devices function both one or two controllers that permit for up to 6GB or 12GB of RAM, respectively. The FAS2240-2 accommodates as much as 4 SAS ports and helps each Ethernet and Fibre Channel connectivity.

NetApp's FAS2200 series at the moment contains two other storage arrays: the FAS2240-4 and the FAS2220. NetApp's naming conference makes use of the number after the hyphen to distinguish between products with the equal model quantity that occupy a distinct number of rack contraptions, indicating that the FAS2240-2 is a 2U gadget, and the FAS2240-4 is a 4U -- however otherwise each FAS2200 devices share a typical design and performance. The FAS2240 features 64-bit Intel Jasper wooded area processors.

The FAS2240-4 emphasizes capacity with support for 1, 2, three, or 4TB HDDs and optional help for 200GB SSDs, where the FAS2240-2 makes use of 450, 600, 900, and 1.2TB HDDs and optionally helps 200GB or 800GB SSDs.  The FAS2220 is a 2U gadget with 12 power bays – half the variety of its siblings – but supports each bulk means and efficiency-oriented drives. in contrast to both FAS2240 instruments, NetApp doesn't present a Fibre Channel Disk Adapter for the FAS2220.

The FAS2200 series utilizes NetApp's Clustered information ONTAP eight working system which presents continuous records entry all the way through scheduled downtime and supports scaling up to 69PB and 24 controller nodes. Clustered information ONTAP abstracts actual storage into a set of Storage VMs (SVM) for native multi-tenant, policy-based mostly storage features by way of programmable APIs and software integrations. The NetApp FAS2240-2 also includes NetApp Flash Accel Server Cache and Flash Pool intelligent Caching, NetApp applied sciences designed to increase performance and cut back storage charges.

  • NetApp FAS2240-2 Design and build

    The NetApp FAS2240-2 is a 2U machine (signified via the number after the hyphen) that ships with a sliding rail package and includes a contemporary faceplate. With the faceplate eliminated, the entrance panel allows for access to twenty-4 2.5-inch force bays, with LED indicators on the left facet signaling popularity and array identity number. each pressure bay has LED warning signs for force status and undertaking.

    The NetApp FAS2240-2 offers 2.5-inch pressure bays which can also be populated with HDDs and SSDs. similar with other commercial enterprise storage solutions, NetApp makes use of a proprietary sled and interposer card to support best qualified storage contraptions.

    Our overview unit aspects a excessive Availability configuration with two Processor handle Modules (PCMs) in addition to redundant vigour give and fan modules. visible below, the NetApp FAS2240-2 is designed to present varied I/O paths for each storage to restrict the chance of one element failure lowering device balance or performance. This incluces using QSFP+ cabling to create an exterior redundant path for storage I/O (anyway inside access) to maintain the equipment online in the event one link is misplaced. An interior heart-beat community link is also used to once more keep things operating smoothly if the leading interior link goes down.

    Onboard PCM I/O comprises 4 Gigabit Ethernet ports for LAN connections and two 6Gb extensive SAS ports for internal and exterior SAS and SATA disks or SAS tape devices. Alternately, the FAS2240-2 will also be transformed to a disk shelf with the aid of replacing the controllers with the corresponding NetApp disk shelf I/O modules. in the graphic under, their system turned into configured with a dual-port 10GbE Twinax add-on card, whereas 2/4/8Gb FC is additionally an choice that may also be swapped with out equipment in a matter of seconds.

    NetApp is a component of the Storage Bridge Bay (SBB) working group, which makes use of an open common for storage arrays, which means that any SBB controller can fit, join, and operate within any storage enclosure controller slot design in keeping with the SBB specification. through implementing the Storage Bridge Bay average, NetApp FAS2240 instruments are in a position to maintain inside a depth of 19-inches to permit for house-limited deployments. essentially the most instant improvement for NetApp FAS2240 customers is increased ease of upgrading from either of the FAS2240 models to another Storage Bridge Bay platform.

    One not obligatory mezzanine card per PCM may also be put in without requiring any hand-equipment to supply 10 Gigabit Ethernet or eight/4/2Gbps Fibre Channel (two ports per card). 10GbE interfaces help Cluster-Mode configurations below data ONTAP 8.1 or excessive-speed client connections, whereas the 8Gbps Fibre Channel card choice can also be configured as a target or an initiator for connectivity with SAN hosts or Fibre Channel disk storage shelves and tape gadgets.

    structure and management

    NetApp provides a device aptly named gadget Setup to get the FAS2240-2 discovered and provisioned once you supply vigour and networking to the system. equipment Setup immediately discovered the FAS2240-2 in their test environment after they entered the subnet to search for the array below (device Setup can additionally act as its own DHCP server when connected to the array through its personal change). The setup manner is designed to handle simple setup wants corresponding to storage pool introduction, administrative passwords and connection IP addresses to get you to a stage the place that you would be able to then hook up with the array via its primary OnCommand equipment manager interface. NetApp also offers an in depth quick setup poster and an array worksheet that properties critical suggestions like IP addresses and passwords. 

    FAS2200 techniques including the FAS2240-2 run NetApp’s statistics ONTAP storage operating device which integrates with a number of NetApp and third-party administrative tools. NetApp OnCommand device manager is a browser-based administration tool that manages particular person NetApp programs for both SAN and NAS environments with a workflow-pushed interface. Flash pool management allows directors to view, create and manage Flash Pool implementations. As with the FAS2240-4, the FAS2240-2 allows for administrators to control up to one hundred twenty extra external disks for a total of 144 disk drives.

    The Disks interface will also be used to control spare disks, create new aggregates, or boost the size of an present combination. The houses area below the listing displays particulars about the selected disk, together with advice in regards to the containing mixture or extent if relevant.

    FAS2240-2 storage efficiency technologies incorporated via NetAppp include RAID-DP, FlexVol, photo copies, deduplication, SnapMirror, and FlexClone. RAID-DP is a double-parity RAID6 implementation that mainly protects against dual disk force failures. skinny provisioning and deduplication aspects can be found by way of NetApp's FlexVol implementation, as well as incremental picture copies. FlexVol can be used to aggregate capacity and efficiency by means of spanning thin or thick provisioned virtual volumes across varied actual storage swimming pools. this may keep time on the executive end by means of permitting you to agonize concerning the datasets being saved as an alternative of the underlying hardware crucial to save it. SnapMirror replicates statistics over native enviornment, wide area, and Fibre Channel networks. FlexClone creates writeable instant copies of records volumes, files, and LUNs, storing handiest records that alterations between the dad or mum and the clone.

    equipment manager offers a wizard to aid in developing an NFS Datastore for VMware for administrators with a licensed NFS provider. The wizard makes it possible for the administrator to create a quantity for the NFS datastore and then specify the ESX servers that may access the NFS datastore.

    Multipath excessive Availability (MP-HA) gives redundant paths between storage controllers and disks for dual-controller excessive availability configurations with a purpose to cut back the possibility of a failover occurring because the outcome of direction failures. MP-HA makes it possible for twice the bandwidth between the SAN and the FAS2240-2 unit in addition to permitting the information ONTAP operating equipment to function protection actions such as disk firmware improvements non-disruptively.

    testing heritage

    The StorageReview enterprise test Lab offers a versatile architecture for conducting benchmarks of business storage devices in an atmosphere corresponding to what SAN directors come across in actual deployments. The enterprise examine Lab incorporates a lot of servers, networking, vigour conditioning, and different network infrastructure that allows their team of workers to set up precise-world conditions to precisely gauge efficiency right through their reports.

    We incorporate these particulars in regards to the lab ambiance and protocols into reviews in order that IT gurus and those liable for storage acquisition can take into account the situations beneath which we've done right here outcomes. None of their stories are paid for or overseen through the manufacturer of equipment they are checking out. extra particulars about the StorageReview enterprise examine Lab and an outline of its networking capabilities are available on those respective pages.

    in an effort to pretty evaluate the efficiency of the NetApp FAS2240-2, deployed dual Lenovo ThinkServer RD630s paired with a Mellanox SX1036 10/40Gb Ethernet change, with connectivity by means of Mellanox ConnectX-3 PCIe adapters. This configuration ensures that the FAS2240-2 is the bottleneck in preference to the SAN; the benchmark consequences under replicate workloads which attain the efficiency obstacles of the storage in preference to other add-ons of the lab infrastructure.

  • business artificial Workload evaluation

    Our enterprise storage benchmark procedure preconditions each and every device into steady-state with the equal workload the gadget will be proven with below a load of sixteen threads with a great queue of sixteen per thread, after which verified in set intervals in numerous thread/queue depth profiles to demonstrate efficiency beneath light and heavy usage.

    Preconditioning and first steady-State exams:

  • Throughput (study+Write IOPS aggregate)
  • common Latency (read+Write Latency Averaged collectively)
  • Max Latency (peak read or Write Latency)
  • Latency typical Deviation (read+Write normal Deviation Averaged together)
  • Our business artificial Workload evaluation contains 4 profiles based on precise-world projects. These profiles were developed to make it less difficult to evaluate to their past benchmarks in addition to broadly-posted values equivalent to max 4k read and write speed and 8k 70/30, which is common for commercial enterprise techniques.

  • 4k
  • one hundred% examine or 100% Write
  • one hundred% 4k
  • 8K (Sequential)
  • 8k 70/30
  • 70% read, 30% Write
  • a hundred% 8k
  • NetApp intends the FAS2240-2 to be constructive as both SAN and NAS storage, so they centered a benchmark protocol that examines the efficiency of the array across both eventualities in every check. consequences when connecting to the FAS2240-2 as part of a SAN are indicated in the key by means of iSCSI, the protocol used to access the storage. When benchmarking NAS performance, consequences are indicated within the key with the aid of SMB, the protocol used for these exams.

    in the first workload, they measured an extended sample of random 4k performance with a hundred% write and 100% read undertaking. throughout the random 4K throughput test they noticed very an identical outcomes across each servers within the the protocol when connecting via iSCSI, with a bit better edition between the two -- but bigger throughput -- by means of SMB. complete throughput by way of iSCSI measured four,732IOPS read and 4,271IOPS write. Benchmarking SMB workloads they carried out a mixed four,659IOPS read and 31,420IOPS write.

    The usual latency uses a large positive queue depth of 512, or 256QD per server. Aggregating effects from each servers, they measured latency of  108.18ms read and 119.84ms write for the iSCSI benchmark and 109.92ms read and sixteen.32ms write latencies via SMB.

    The optimum latency outcomes replicate the worst case state of affairs from the 4k throughput benchmark. For each iSCSI and SMB, the effects between the two servers were exceptionally constant. In their test of iSCSI throughput, the NetApp FAS2240-2 finished a maximum study latency of 2033.0ms in the 4k examine and a optimum write latency of 3093.5ms aggregated throughout each servers. during the SMB throughput benchmark, the FAS2240-2 maintained a maximum examine latency of 294.5 and a maximum write latency of 75.5ms.

    In distinction to the highest latency record, general deviation displays how constant the NetApp FAS2240-2 changed into able to hold latency performance in preference to the worst case state of affairs. linked by the use of iSCSI, the FAS2240-2 maintained a common deviation of 55.02ms for study operations and 97.32ms in write operations right through the 4k benchmark. within the SMB protocol, the FAS2240-2 stored performance very tight across the benchmark, with a regular usual deviation for both servers of 5.96ms read and 8.35ms write.

    The subsequent benchmark measures 100% 8K sequential throughput with a 16T/16Q load for one hundred% examine and one hundred% write operations. With a handiest minor discrepencies in write performance between both servers used during this protocol, the NetApp FAS2240-2 accomplished a combined 121,460IOPS examine efficiency and forty five,047IOPS write efficiency when accessed via iSCSI. Switching to SMB connectivity, the FAS2240-2 kept performance for both servers a good deal tighter albeit with reduce aggregated througput of forty seven,374IOPS read and 27,282IOPS write.

    The next artificial commercial enterprise benchmark measures throughput with an 8k transfer measurement and 70% study operations and 30% write operations. This benchmark utilizes quite a lot of thread and queue depth combinations from 2 threads and a queue of two up to sixteen threads and a queue depth of sixteen. The chart makes it less difficult to establish the approximate doubling of efficiency when moving from iSCSI connectivity (pink shades) to SMB connectivity (blue colours) in the 8k 70% study, 30% write benchmark. efficiency was predictably weakest for both connection protocols in instances where the thread count number was excessive and the queue depth become low.

    Charting the typical latency within the 8k 70% study and 30% write benchmark suggests very consistent efficiency between servers, with the SMB-connected protocol leading to lower commonplace latencies however with expected peaks in normal latency at excessive queue depths.

    The optimum latency consequences reveal a more complex image than general latency alone would indicate. As with normal latency, the SMB outcomes have the most excellent maximum latency performance below lighter hundreds, however that distinction starts to disappear at higher queue depths as soon as the benchmark reaches a thread count number of 4. each iSCSI and SMB effects reach highest latencies above one 2nd a high queue depths for the the rest of the benchmark which reflects an underlying problem of the platform that is not elegant on the protocol.

    Plotting ordinary deviation in latency results for the 8k 70/30 benchmark produces consequences that are in keeping with expectations and the 4k benchmark results, with SMB retaining the upper hand with extra constant latencies and both protocols experiencing their most useful range of latency model with long queues.

    Our remaining benchmark measures sequential 128k switch pace with a 16T/16Q workload on a hundred% read and one hundred% write operations. When connected by way of iSCSI, they mentioned a discrepency of very nearly 100,000KB/s in read performance between Server 1 and Server 2. total iSCSI throughput within the 128k protocol reached 1,247,666KB/s examine and 571,454KB/s write. performance in the SMB check became decrease, albeit with less version between servers with a total of 408,305KB/s read and 236KB/s write.

    Conclusion

    NetApp has engineered the FAS2240-2 to accommodate generational improvements as well as scale-out scenarios. SMB consumers can start with the FAS2240-2 as the center of a small NAS or SAN answer, expand it with external disk shelves as potential necessities boost, after which convert the FAS2240-2 itself to a disk shelf as it reaches the end of its valuable life with the aid of swapping out the controller modules. considering the whole FAS line of disk arrays will also be managed with OnCommand equipment manager, the getting to know curve as an infrastructure grows is minimal. extra, integration with windows and VMware additionally simplify deployments and assist the NetApp methods seamlessly blend into an current IT environment. For better enterprises, the FAS2200 collection serves as a simple to manage faraway workplace or department office storage. thanks to features like far flung replication, branch/far flung workplace users can have native access to key information while not having to be troubled about managing their personal backup routines. The FAS2200 collection household is fairly bendy and incorporates a beginning expense aspect of under $8,000.

    On the flexibility element, one hardware characteristic value noting within the FAS2240-2 is the interconnect alternate options. Many arrays during this type offer Ethernet and 10GbE or 8Gb/s Fibre Channel as interconnect alternate options. The FAS2240-2 we reviewed turned into configured with a dual-port 10GbE Twinax add-on card but simply as comfortably a customer may decide on an 8Gb/s Fibre Channel mezzanine card. Switching between both if necessary is a simple project and takes just a couple of minutes. additionally, whereas now not tested during this evaluate, the FAS2200 collection can aid flash disks for those who require flash pools for greater stressful applications and workloads.

    In their checking out ambiance they were in a position to bring the FAS2240-2 online immediately and get LUNs and shared folders provisioned in minutes from a fresh out of box condition. In their benchmarks they found the lively/lively controller setup to supply mighty efficiency throughout each iSCSI and CIFS, with CIFS displaying a robust write caching tendency even with look at various pattern sizes extensively larger than controller DRAM amounts. when it comes to height I/O they had been capable of pull up to 121k sequential IOPS read in their 8K workload over iSCSI, losing to round 4,seven-hundred IOPS examine with a random 4K workload also over iSCSI. height bandwidth from the FAS2240-2 measured 1.2GB/s study and 571MB/s write over iSCSI, whereas CIFS bandwidth came in reduce at 408MB/s read and 236MB/s write. average for a 100% HDD configuration with out a SSD caching added, the FAS2240-2 become capable of demonstrate a variety of muscle and continue to be very versatile throughout assorted storage interfaces.

    professionals

  • bendy upgrade paths by way of external disk shelves and swappable storage modules
  • distinct user-upgradable interconnect alternatives to support both 10Gb Ethernet and 8Gb Fibre Channel environments
  • supports all primary interface requisites including iSCSI, CIFS and NFS
  • Cons

  • Unbalanced block and file efficiency
  • final analysis

    The NetApp FAS2240-2 is a versatile unified storage array it's extremely simple to deploy and manipulate, yet has the capability to grow with an organization's facts needs. Equally at domestic as the crucial storage repository for a SMB or in a department/far off workplace for a larger commercial enterprise, the FAS2240-2 delivers an entire set of business points with an aggressive beginning cost factor.
