Dell Compellent

� Mixing RAID types within a pool or disk group set is possible
� Tiering is done at 2 MB by default, though administrators have the option to manage storage blocks at 512 KB or 4 MB pages
� Tiering profiles can be applied to single LUNs or groups of LUNs
� Profiles specify not only the tiers to be used for each volume, but also the disk types, rotational speeds and RAID levels within each tier.
� With Dell Compellent there is no write penalty for migrating data to lower tiers.
Tiered storage solutions within traditional storage architectures cannot deliver the same level of write performance. In those solutions, data is written to a particular block and kept in that block. If the block is migrated to tier 3 and a new write comes in for that volume, the write will occur on tier 3.
� Dell Compellent snapshots do not reside within the volume with production data � they sit outside the production volume in pages within the general virtual storage pool
� Dell Compellent Fast Track augments Automated Tiered Storage by delivering optimal placement of data on each individual disk.
Fast Track uses the intelligence continuously collected by the Dell Compellent system to identify the most active, frequently accessed blocks of data on each spindle. It then places those data blocks together on the outer tracks of each drive. Keeping the head focused on that one area of the disk, where the active data resides, delivers better performance than if the head were forced to move all over the disk.
� Writes are always written to tier 1 RAID 10, large sequential write workloads will hit tier 1,
Migration occurs automatically at a set time defined by the user, or on demand, while the system is
still online. The migration process runs in the background and does not affect data availability or
application performance. There is no need to bring down an application, pause I/O or wait for a
minimum I/O requirement. If a read request comes in to a page that is being moved, the request is
satisfied from the original placement of the page. The page is then moved after the read is complete.
If a write request comes in, it will not interfere with the migration process, as new information is
always written to tier 1, RAID 10�and therefore is not eligible for migration. Overwriting a block of
protected information also occurs on tier 1, RAID 10, so moving a block of data receiving writes simply
will not occur. There is never a situation when application I/O is denied�application requests always
receive priority.
In the Dell Compellent architecture, new data is written by default to tier 1, RAID 10 storage to
provide the best write performance.
� Activating the tiering functionality requires a module-specific license, but perpetual licensing ensures that organizations only incur additional licensing expenses when adding more capacity to an existing system. Upgrading to a new controller with the latest technologies does not require a new software license, as is the case with other solutions.
� In the Dell Compellent architecture, new data is written by default to tier 1, RAID 10 storage to provide the best write performance. Replays move to a lower storage tier with RAID 5 or 6 protection during the next migration cycle within a 24-hour window. And over time, according to the tiering profile, infrequently accessed blocks of data move to a lower storage tier and RAID level, or to a different RAID level within the same tier. Moving this read-only data from RAID 10 to RAID 5 within the same tier enables administrators to maintain the same read performance.
Not sure that that read performance will be the same when a block of data within a tier is moved between RAID types (RAID 5 read perform is superior to RAID 10)
� When new data needs to be written to an existing block that has since been converted to read-only and migrated to a lower tier, those writes are redirected to the tier 1, RAID 10 storage. A new writable block is automatically allocated to provide the highest transaction performance. Virtual pointers utilize the use characteristics of those blocks to maintain data continuity. All data is written to tier 1, yet snaphsots move to the lower tier available within 24 hours for the highest write and read performance possible. Virtual pointer retain continuity between all associated blocks.

Dell sells Ubuntu But its NOT recommended says this CSR

Surely, I am an advocate of Dell (and system76.com, and now HP for mobile mi(its Ubuntu)) because of their GUTS to sell GNU/Linux to end users! That being said, I wanted for people to see this story to raise awareness. Regular people are getting pushed around, being discouraged from choice, and soldiers of freedom MUST ANSWER! BRING IT ON!!

Dell EqualLogic

The following notes were taken during an interesting meeting we had with a delegation from Dell. The post is composed in the form of a question and answers session for clarity of presentation � even though most of the information was intelligently proferred without any initial question � and the questions are not put in any particular order. The answers are not the words of the Dell delegates themselves, and I apologize in advance if there is any mis-representation.

Q: Does EqualLogic support dedupe?
A: No, dedupe is not a feature provided by EqualLogic. If you are looking for an excellent, cost-effective dedupe appliance, we can highly recommend the DR4000. The DR4000 uses inline dedupe, and it is packed with high-levels of processing power to enable high-throughput levels. This storage is highly recommended for backup storage and allows for replication of deduped backups off site.
Note: Not recommended to run production/live virtual machines off this.

Q: What snapshot mechanism does EqualLogic use?
A: EqualLogic uses the Allocate-On-Write (AOW) snapshot mechanism. This has performance advantages over the Copy-On-Write (COW) mechanism, and also allows for the live mounting of volume snapshots without affecting the primary volume.
Notes: The following extract explaining Copy-On-Write versus Allocate-On-Write is taken from http://www.dcig.com/2011/03/another-look-at-what-is-the-best-snapshot.html
A copy-on-write snapshot incurs a performance penalty anytime previously written data is changed. In these circumstances, the previously written block of data first has to be read, re-written to another block of storage and then the new data written where the other data previously resided.
Allocate-on-write conversely "freezes" data that was previously written and writes changes to that data elsewhere on other disk. This eliminates the three step "read, rewrite and write" process associated with copy-on-write and reduces snapshots to just one step - a write.

Q: Does EqualLogic support Synchronous Replication?
A: Not yet, this is in the pipeline.

Q: Does EqualLogic support a Thin Provisioned LUN Space Reclaimer?
A: Not yet, this is in the pipeline.

Q: What best practices do you recommend as regards RAID setup?
A: This all depends on the environment and use scenario, which is why Dell have invested $1000000s in developing DPACK (Dell Performance Analysis Collection Kit) which is available to partners. The DPACK can be run over a typical working day to pick up various disk utilization statistics, and will then recommend which EqualLogic model(s) to go for, and the recommended RAID setup.

Q: Does EqualLogic support data auto tiering / load balancing (intelligent data tiering)?
A: Yes!
Notes: The following extract is taken from http://up2v.nl/2011/10/30/dell-equallogic-version-5-1-firmware-overview/
Dell added a new loadbalancer called Automatic Performance Load Balancer or APLB. This automatically moves blocks of data between pools of different controllers, RAID set or disk types. This means you can create a pool of disk drives containing different characteristics, like SAS and nearline SAS or SATA. As a administrator you do not have to worry anymore where to place the data. Also when administrator finds out an application needs more iops, he does not need to move data manually to high performance tier of storage. APLB will make sure the most accessed data will be placed on the fastest drives (the drives with the least latency).
For consideration: Consider the intelligent moving of blocks of data by the storage array to maximize storage performance, versus VMware vSphere 5s Storage DRS which has to move the entire datastore � which one do you think is better?

Q: How expandable is an EqualLogic PS-Series Array?
A: EqualLogics are expanded by purchasing additional PS-Series Arrays. You can have up to 16 members in a group and 8 in a pool. The members can be different models of EqualLogic, with different types of disks. And there is no reason why you cannot continue to expand your group over time keeping the older EqualLogics in place and adding additional EqualLogics as need arises. The older PS-Series appliances going back over 7+ years continue to support the latest firmware and features, and the current models will continue to do the same, future-proofing and maximizing the return on your investment.

Q: Can I buy storage shelves to expand my EqualLogic PS-Series Array?
A: No. The reasoning behind this is that as you add more storage shelves to a controller unit, the demand placed on that controller unit goes up and up. Also, adding more shelves to a controller unit does not increase the number of I/O ports. With the EqualLogic you expand by adding additional PS-Series storage arrays, linearly increasing the number of high performance controllers and I/O ports.

Q: Can I mix and match different types of disk in an EqualLogic PS-Series Array?
A: No, each separate array will have a set of identical disks. Within a pool you can have different types of arrays with SATA, SAS, etcetera...
Note: An exception is the PS6100XS which has 7 SSDs and 17 SAS drives with intelligent data tiering.

Q: Which EqualLogic Array would you recommend for VDI deployments?
A: An excellent storage appliance to use for VDI solutions is the PS6100XS, this specialist unit has 7 SSDs and 17 SAS drives, and uses intelligent data tiering. Youd be looking at running 250 typical virtual desktops from just one unit.
Note (i): Dont take my word for this, please check with your Dell partner first. It may well be that you will get more much more than 250 virtual desktops running off one PS6100XS.
Note (ii): A certain world famous retail company uses 3 of the predecessor units to the PS6100XS, to service a near 1000 desktop VMware View VDI farm.

Q: Does EqualLogic do CIFS/NFS?
A: The EqualLogic FS7500 is designed for CIFS/NFS implementations. Essentially you just present the storage as shares, there are no LUN configurations required.
Note: Traditionally EqualLogic arrays have always been iSCSI.

Q: Why does EqualLogic not support having active/active controllers?
A: This is a very good question. EqualLogic runs the active and passive controllers connected by a thick I/O pipe that effectively maintains the passive controller as a mirror of the active controller, this allows for near instantaneous failover in the event of a RAID controller failure � there is no need for the controller having to seize ownership of the failed controllers disks. This is supported by write cache mirroring and the write cache is cached to flash memory.
Note: The process of controller failover uses MAC spoofing and needs portfast and rapid spanning tree enabled on switches.

Q: Nothing to do with EqualLogic per-se � are 3.5" disks faster than 2.5" disks?
A: Technically speaking, with the same disk spin speed, if your data blocks are on the edge of a 3.5" disk it will be slightly faster read/write than if it were on the edge of a 2.5" disk. In practice there is nothing really in it (especially if you can pack in more 2.5" disks and thus have more spindles which means more IOPs.)

Dell is utterly bizarre

Dell has a gorgeous new laptop . . . almost out. Pictures are on various blogs. The thing is thinner than a MacBook Air and has an intriguing and showy way of folding open. So, youd think thered be mention of the product on Dells website? Youd think, but no!
