Today’s data centers are being asked to do more with little additional financial support forthcoming. They are under a constant barrage to do things faster, more inexpensively and with no disruption to the revenue-­‐generating part of the company. Frequently, they are experiencing 24 X 7 operations, numerous new application deployments and explosive data growth. Data storage often becomes a crucial limiting factor to meeting these stringent demands.

Faced with these seemingly insurmountable challenges, CIO’s are discovering that the old way of responding to application and data growth is unacceptable. That is, the outdated “rip and replace” method to improve capacity and IO performance, which often meant disruptive migration, doesn’t work anymore. Instead, a more nimble alternative is needed. In response to this need for storage agility, NetApp has recently released a new version of their storage operating environment called Data ONTAP® 8.1. This new software update successfully eliminates many problems of typical monolithic or legacy storage systems.

NetApp Unified Scale-Out/Clustered Storage NetApp Unified Scale-Out/Clustered Storage Document Transcript

  • Silverton Consulting, Inc. StorInt™ Briefing   Introduction     Today’s  data  centers  are  being  asked  to  do  more  with  little  additional  financial   support  forthcoming.    They  are  under  a  constant  barrage  to  do  things  faster,  more   inexpensively  and  with  no  disruption  to  the  revenue-­‐generating  part  of  the   company.    Frequently,  they  are  experiencing  24  X  7  operations,  numerous  new   application  deployments  and  explosive  data  growth.    Data  storage  often  becomes  a   crucial  limiting  factor  to  meeting  these  stringent  demands.     Faced  with  these  seemingly  insurmountable  challenges,  CIO’s  are  discovering  that   the  old  way  of  responding  to  application  and  data  growth  is  unacceptable.      That  is,   the  outdated  “rip  and  replace”  method  to  improve  capacity  and  IO  performance,   which  often  meant  disruptive  migration,  doesn’t  work  anymore.    Instead,  a  more   nimble  alternative  is  needed.    In  response  to  this  need  for  storage  agility,  NetApp   has  recently  released  a  new  version  of  their  storage  operating  environment  called   Data  ONTAP®  8.1.    This  new  software  update  successfully  eliminates  many   problems  of  typical  monolithic  or  legacy  storage  systems.   Why  unified  scale-­‐out  architecture  can  help   By  definition,  monolithic  storage  is  only  minimally  flexible.    Each  storage  system  is   equipped  with  a  set  of  processing  elements  (controllers)  and  storage  drive   expansion  shelves.    The  storage  can  be  scaled  up  to  match  increasing  capacity  and   performance  demands,  but  the  improvement  options  are  limited.      For  example,   maximum  capacity  for  a  particular  system  is  restricted  to  the  drives  and  expansion   shelves  supported.    Similarly,  performance  scalability  is  also  confined  to  increasing   cache,  drives  and/or  ports.    Thus,  any  significant  improvement  in  capacity  or   performance  generally  requires  a  stressful  and  disruptive  replacement  process.   Probably  the  most  difficult  part  of  this  process  is  the  successful  migration  of  the   data  itself,  but  perhaps  the  most  frustrating  part  is  knowing  that  the  whole  change   out  process  will  be  repeated  in  a  couple  of  years.       In  contrast,  unified  scale-­‐out  storage  architecture  provides  almost  limitless  scale  out   possibilities,  with  support  for  both  file  and  block  protocols,  as  well  as  enterprise  and   technical  workloads.    By  simply  adding  nodes  to  the  storage  group,  capacity  and   performance  can  be  scaled  to  match  current  needs  and  then  later  easily  re-­‐scaled  to   meet  future  needs.    Moreover,  this  system  enhancement  requires  no  disruption  of   ongoing  operations.       ©  2012  Silverton  Consulting,  Inc.   Page  1  of  9  twitter.com/RayLucchesi|RayOnStorage.com   All  Rights  Reserved   +1-720-221-7270|SilvertonConsulting.com
  •   NetApp  Unified  Scale-­out  Storage         Technology  refresh  is  another  instance  where  unified  scale-­‐out  storage  architecture   can  be  extremely  beneficial.    Over  time  a  storage  cluster’s  technology  can  be   upgraded  by  first  adding  new  system  nodes  and  then  reconfiguring  and  moving  the   data  from  the  old  to  the  new  storage.  As  a  result,  the  entire  storage  cluster  evolves   to  provide  better  services  to  the  data  center.    Again  all  is  done  without  disruption.     Yet  another  noteworthy  benefit  of  unified  scale-­‐out  architecture  is  that  both  IT’s   unstructured  as  well  as  structured  data  can  be  managed  within  the  same  storage   cluster.    Thus,  as  file  and/or  block  needs  change,  the  unified  storage  cluster  is  ready   to  handle  both  in  whatever  proportion  the  business  requires.   NetApp’s  unified  scale-­‐out  storage   NetApp  introduced  scale-­‐out  storage  services  with  the  release  of  Data  ONTAP  8.0   operating  in  Cluster-­‐Mode  in  2009.    With  this  advance,  NetApp  transformed  their   systems  to  include  the  ability  to  scale  up  and  scale-­‐out  a  multi-­‐node  storage  cluster.     As  such,  a  single  NetApp  storage  cluster  can  scale  capacity  from  TBs  to  tens  of  PBs,   but  even  more  importantly  it  can  scale  performance  from  a  single  system  to  a  multi-­‐ node  storage  complex,  all  managed  as  a  single  system.     As  shown  in  Figure  1,  a  NetApp  scale-­‐out  cluster   consists  of  one  or  more  HA-­‐pairs  of  storage  systems   that,  with  the  latest  ONTAP  8.1.1,  can  grow  to  3-­‐HA   pairs  for  SAN  or  unified  storage  (6-­‐node  SAN  &  NAS)   or  12-­‐HA  pairs  for  NAS  only  storage  (24-­‐node  NAS).       Physical  storage  resources  are  pooled  across  the   cluster  and  are  available  to  service  any  IO  request   coming  into  the  system.    Nodes  in  the  cluster   communicate  using  a  private  10GbE  interconnect   network.         NetApp  storage  cluster  services  are  defined  on  top  of   Vservers  that  provide  a  logical  interface  to  physical   resources.    These  Vservers  can  span  physical  storage   nodes  and  can  house  multiple  LUNS  and  volumes  as   Figure  1  Cluster  Configuration     needed.       ©  2012  NetApp     With  NetApp’s  Data  ONTAP  8.1.1,  Infinite  Volume  support  for  NFS  Enterprise   Content  Repositories  is  provided.    With  this  capability,  Data  ONTAP  8.1.1  can  link   multiple  volumes  across  cluster  nodes  to  create  a  single  file  system  that  can  scale  up   to  a  maximum  20PB  and  hold  billions  of  files.    However,  the  first  target  application   for  Infinite  Volume  requires  a  single  Vserver  spanning  an  entire  storage  cluster.       Currently,  an  Infinite  Volume  storage  cluster  is  limited  to  a  10-­‐node  (5  HA-­‐pair)   configuration  of  NetApp  FAS6280s.       ©  2012  Silverton  Consulting,  Inc.   Page  2  of  9  twitter.com/RayLucchesi|RayOnStorage.com   All  Rights  Reserved   +1-720-221-7270|SilvertonConsulting.com
  •   NetApp  Unified  Scale-­out  Storage         Under  NetApp’s  storage  cluster  design,  volumes  holding  user  data  are  assigned  to  a   single  Vserver  but  can  actually  be  located  on  any  physical  aggregate  in  the  cluster.     As  a  result,  these  volumes  can  be  non-­‐disruptively  moved  between  physical   aggregates  within  the  cluster.    With  this  capability,  NetApp  Data  ONTAP  8.1.1   creates  an  almost  immortal  storage  cluster.  That  is,  simply  by  adding  new  storage   technology  to  the  cluster  and  migrating  data  from  the  old  to  new  storage,  the   reconfigured  cluster  is  revitalized.    In  fact,  over  a  cluster’s  lifetime,  storage  nodes   can  be  added  and/or  replaced  repeatedly  without  disruption.     Moreover,  as  storage  nodes  are  changed  or  added,  data  can  be  easily  re-­‐balanced   across  the  cluster.  In  this  fashion,  IT  can  choose  to  add  performance  to  current   workloads  or  reserve  the  new  performance  and  capacity  for  other  activity.    All  this   flexibility  is  a  result  of  Vservers  that  can  grow  or  shrink  as  needs  dictate,  such  that   the  cluster  evolves  over  time  without  disruption.       Each  NetApp  Vserver  can  represent  a  distinct  administration  domain  and  thus,  can   be  managed  separately  from  any  other  Vserver  in  the  cluster.    As  such,  separate   Vservers  can  be  used  to  support  different  customers,  segregating  cluster  data  and   other  resources  for  a  multi-­‐tenant  storage  environment.    Alternatively,  the  whole   storage  cluster  could  be  configured  with  just  one  Vserver  to  create  a  single,  large   administration  domain.     With  the  masterly  design  of  Data  ONTAP  8.1.1,  NetApp  unified  scale-­‐out  storage  can   increase  performance  and  capacity  in  almost  any  combination.    But,  even  more   impressive,  the  number  of  combinations  can  be  multiplied  by  adding  different   models  of  NetApp  storage  to  a  cluster.  For  example,  multiple  HA-­‐pairs  of  FAS3240s   and  FAS6240s  could  be  combined  within  the  same  cluster.    In  this  way,  IT  can   determine  how  much  performance  and  capacity  to  use  for  a  given  environment.     Outside  of  a  cluster  configuration  such  fine  granularity  of  capacity  and  performance   scaling  is  not  possible.       Fortunately,  NetApp’s  storage  cluster  can  also  include  third  party  storage.  In  fact,   with  NetApp  V-­‐Series  Open  Storage  Controllers  or  storage  virtualization  services,   even  third  party,  legacy  storage  arrays  can  provide  scale  out  performance.  V-­‐Series   virtualization  adds  advanced  functionality  like  storage  efficiency  features  to   existing,  older  legacy  storage  arrays.    Combining  storage  virtualization  capabilities   like  these  with  clustering  makes  for  an  even  more  flexible  environment  as  migration   can  now  be  non-­‐disruptive  not  only  within  a  V-­‐Series  storage  complex  but  also   across  the  cluster.  Of  course,  NetApp’s  other  advanced  features  such  as  integrated   data  protection  and  Flash  Cache  can  also  be  automatically  applied  to  any  supported   backend  storage.    With  such  capabilities,  NetApp  V-­‐Series  can  indeed  reinvigorate   less  sophisticated  storage.       ©  2012  Silverton  Consulting,  Inc.   Page  3  of  9  twitter.com/RayLucchesi|RayOnStorage.com   All  Rights  Reserved   +1-720-221-7270|SilvertonConsulting.com
  •   NetApp  Unified  Scale-­out  Storage         Other  new  features  for  Data  ONTAP  8.1.1   In  addition  to  the  enhanced  scale-­‐out  features  discussed  above,  Data  ONTAP  8.1.1   offers  additional  new  capabilities  for  NetApp  storage.    Specifically,  ONTAP  8.1.1   introduces  new  SSD  support  for  aggregate  level  read  and  write  caching,  as  well  as   virtual  appliance  capabilities  to  their  storage  portfolio.   Flash  Pool     NetApp  was  the  first  enterprise  class  storage  to  take  advantage  of  NAND  memory  in   their  storage  controller  with  Flash  Cache.    With  Flash  Pool,  NetApp  combines  new   support  for  SSDs  and  disk  devices  into  a  single  Data  ONTAP  aggregate.    A  Flash  Pool   consists  of  an  aggregate  with  one  or  more  disk  RAID  groups  together  with  a  single   SSD  RAID  group.    SSDs  in  a  Flash  Pool  can  be  used  as  a  read  or  a  read-­‐write  cache  for   the  disk  data  held  in  the  aggregate.    Also,  disk-­‐only  aggregates  can  be  non-­‐ disruptively  upgraded  to  a  Flash  Pool  by  adding  SSDs.    Here  again  caching  hot  data   on  SSDs  while  leaving  all  data  on  disk  storage  can  significantly  improve   performance.     Data  ONTAP  Edge  or  virtual  storage  appliance   Another  addition  to  NetApp  storage  with  Data  ONTAP  8.1.1  is  a  new  virtual  storage   appliance.    Data  ONTAP  Edge  is  Data  ONTAP  running  on  a  virtual  machine  in  the   VMware  Vsphere  environment.    It  supports  NetApp  storage  services  using  VMware   direct  attached  storage  and  a  backup  connection  to  a  central  data  center  using   NetApp  SnapVault.  The  virtual  appliance  is  customized  for  those  remote  and/or   branch  office  environments  that  need  shared,  sophisticated  storage  functionality  but   cannot  afford  the  cost  and  power  of  a  stand-­‐alone,  hardware  storage  system.    While   the  virtual  storage  appliance  doesn’t  support  all  NetApp  advanced  features  it  does   support  SnapVault,  FlexClone,  SnapRestore,  deduplication  and  thin  provisioning,   enabling  a  remote  or  branch  office  to  quickly  and  efficiently  backup  their  data  to  a   central  NetApp  storage  system.   Other  benefits  of  NetApp  unified  scale-­‐out  storage   NetApp’s  unified  scale-­‐out  storage  can  also  provide  all  the  state-­‐of-­‐the-­‐art  storage   efficiency  features  NetApp  offers  such  as  deduplication,  compression  and  thin   provisioning.    These  capabilities  alone  can  often  reduce  physical  storage  capacity   requirements  by  up  to50  percent  while  having  little  impact  on  IO  performance.     In  addition,  NetApp’s  unified  scale-­‐out  storage  provides  access  to  NetApp’s   integrated  data  protection  services  such  as  Snapshot  and  SnapMirror  that  can  be   used  to  easily  and  efficiently  protect  data  stored  within  the  cluster.    When  combined   with  the  storage  efficiency  features  mentioned  above,  Snapshot  is  even  more  space   efficient  and  thus,  less  costly.         Moreover,  SnapMirror  provides  data  replication  or  mirroring  across  NetApp  storage   systems.    SnapMirror  can  also  make  use  of  advanced  efficiency  features  enabled  for     ©  2012  Silverton  Consulting,  Inc.   Page  4  of  9  twitter.com/RayLucchesi|RayOnStorage.com   All  Rights  Reserved   +1-720-221-7270|SilvertonConsulting.com

  •   NetApp  Unified  Scale-­out  Storage         Thus,  as  can  be  seen  in  Figure  2,  one   extraordinary  characteristic  of   NetApp’s  Cluster-­‐Mode  services  is   the  relative  linearity  of  incremental   performance  increase  with  the   addition  of  more  storage  nodes.  For   example,  at  4-­‐nodes,  the  per  node   NFS  throughput  was  ~65.1K   operations  per  second  and  at  24-­‐ nodes,  the  per  node  NFS  throughput   was  still  ~63.0K  operations  per   second.       Figure  2  NetApp  cluster  mode  performance  per  node   For  all  the  Cluster-­‐Mode  FAS6240   benchmarks,  NFS  Overall  Response   Time  (ORT)  or  average   responsiveness  ranged  from  a  low   of  1.48  to  a  high  of  1.55   milliseconds.    Thus,  as  shown  in   Figure  3,  response  time  did  not   suffer  by  adding  further  nodes.    In   fact,  with  the  4-­‐node  storage   cluster,  response  time  was  1.53   milliseconds  and  with  the  24-­‐node   storage  cluster,  the  response  time   was  also  1.53  milliseconds.    Even   Figure  3  NetApp  cluster  mode  overall  response   with  the  dramatic  throughput   time   increases  afforded  by  multiple  node   additions,  clustering  had  no  apparent  negative  impact  on  response  times.   NetApp  Clustering  block  (SAN)  performance   In  addition  to  the  file  services  Cluster-­‐Mode  benchmarks  reported  on  above,  NetApp   also  submitted  a  6-­‐node  FAS6240  unified  storage  cluster  for  Storage  Performance   Council  SPC-­‐1  block  performance  testing  running  Data  ONTAP  8.1.1.[2]    The  results   for  NetApp’s  Cluster-­‐Mode  SPC-­‐1  benchmark  were  ~250,000  SPC-­‐1  IOPS™  (I/O   operations  per  second),  $6.69  $/IOPS™  ($  per  I/O  operations  per  second)  and  a   LRT™  (least  response  time)  of  0.99  milliseconds.    This  modular  scale-­‐out  model  of   NetApp  provides  the  foundation  for  continued  growth  as  both  controller   performance  and  node  count  increases  over  time.  In  terms  of  relative  performance,   the  6-­‐Node  FAS6240  is  in  the  top  10%  of  submitted  configurations  as  measured  by                                                                                                                   [2]  Available  from  SPC-­‐1  results  website    http://www.storageperformance.org/results/benchmark_results_spc1#a00115  as   of  21Jun2012.     ©  2012  Silverton  Consulting,  Inc.   Page  7  of  9  twitter.com/RayLucchesi|RayOnStorage.com   All  Rights  Reserved   +1-720-221-7270|SilvertonConsulting.com
  •   NetApp  Unified  Scale-­out  Storage         LRT  and  the  IOPs  measures  represent  a  267%  increase  in  performance  and  12%   reduction  in  cost  relative  to  the  FAS3270  SPC-­‐1  publication.  Further,  NetApp  uses   list  pricing  in  their  SPC-­‐1  submissions  while  almost  all  other  vendors  use  discounted   pricing,  resulting  in  a  $/IOPS  that  is  both  more  conservative  and  verifiable  than  the   competition Customers  benefiting  from  NetApp’s  unified  scale-­‐out  storage   As  discussed  above,  NetApp  storage  clusters  have  been  validated  with  both  industry   standard  file  and  block  storage  benchmarks  and  as  such,  are  unquestionably   enterprise  ready.    As  further  proof,  NetApp  unified  scale-­‐out  storage  supports  the   following  partial  list  of  applications,  virtualization  systems  and  operating  systems:     • Software  applications  –  Oracle,  Microsoft  SQL  Server,  Microsoft  SharePoint,   Microsoft  Exchange  and  SAP,   • Server  virtualization  systems  –  Microsoft,  VMware  and  Citrix,   • Operating  systems  -­‐  HP-­‐UX,  AIX,  Red  Hat,  SLES,  Solaris  and  Windows.     Given  this  wide  array  of  compatibility,  NetApp  storage  clusters  could  readily   support  virtually  any  file  or  block  services  environment  existing  today.       High  file  access  operations   Moreover,  because  of  the  exceptional  ~64,000  per  node  NFS  ops/second,  the   powerful  NetApp  FAS6240  storage  cluster  should  perform  admirably  for  most  high-­‐ end  file  services  workloads.    Plus,  the  storage  cluster  could  be  scaled  to  the   performance  required  by  using  other  NetApp  models  such  as  FAS3200  and  other   FAS6200  series  storage.    For  example,  a  data  center  could  start  with  a  2-­‐node   FAS3210  CIFS/SMB  or  NFS  storage  cluster  to  support  mid-­‐size  data  center   requirements.    Rapid  growth  could  be  easily  and  efficiently  accommodated  by   adding  more  FAS3210’s  or  FAS3240  HA-­‐pairs.    Connecting  FAS6200  series  storage   to  the  cluster  could  readily  support  even  further  rapid  growth.    During  this   evolution,  storage  performance  would  grow  from  thousands  to  over  a  million  NFS   operations  per  second  and  capacity  would  grow  from  TB  to  tens  of  PB  of  storage  all   within  the  same  cluster  and  without  incurring  any  disruption.       Random  IOPS  performance   Similarly,  almost  any  block  storage  environment  can  benefit  from  NetApp  storage   clusters.    By  moving  to  NetApp  scale  out  unified  storage,  random  block  performance   can  scale  from  thousands  to  over  a  quarter  of  a  million  IO  operations  per  second   with  commensurate  increases  in  maximum  capacity.   Summary   NetApp’s  cluster  architecture  has  an  exceedingly  versatile  and  agile  design.    Not   only  can  different  NetApp  storage  models  (11  current  models  plus  9  legacy  models)   be  configured  to  operate  in  sync  within  the  cluster,  but  also  with  NetApp’s  V-­‐Series     ©  2012  Silverton  Consulting,  Inc.   Page  8  of  9  twitter.com/RayLucchesi|RayOnStorage.com   All  Rights  Reserved   +1-720-221-7270|SilvertonConsulting.com
