QxDoes this become a good solution for healthcare - faster processing of patient data and images? 02/27/2014 11:18AM

AYes, this becomes a great solution for the healthcare industry. Customers with data-intensive multi-workload environments such as: real-time analytics and intelligence, batch processing, email, online transaction processing (OLTP), video, virtual desktops, database loads, and high-performance computing (HPC) will benefit the most from the UCS Invicta.02/27/2014 11:23AM

QThe Register covered the Invicta saying "The array still links to UCS servers via a network link – Ethernet or Fibre Channel – and still provides flash storage resources to a bunch of servers over these network pipes, just like EMC's XtremIO array and NetApp’s EF540/550" etc. How is Invicta different? 02/27/2014 11:09AM

ACisco saw a strategic need, based on customer demand, to integrate flash systems directly into the Unified Management control plane of UCS. Joint solutions with our storage partners do not fully meet this need. Cisco UCS will continue as an open system and we will support interoperability and certification with all of our partner’s Flash- and Disk-based storage systems.02/27/2014 11:24AM

QIs this being recorded for later playback? 02/27/2014 11:23AM

AThis event will be archived and available for on-demand viewing within 1-2 days. You can use the same event link to access the archived event. 02/27/2014 11:24AM

QDo we have a better/compelling story to tell with MDS and UCS Invicta? 02/27/2014 11:08AM

AThe UCS + MDS value proposition is well established in the market. There are key technologies that are only enabled with they are both used together such as FC port channeling and VSAN trunking. Now we have the ability to add UCS Invicta storage to the architecture and over time build out technology integration. 02/27/2014 11:25AM

QDoes Invicta have any unique or proprietary integration with UCS?02/27/2014 11:11AM

AWe have a compelling road map that we will be aggressively executing on. Contact your Cisco account team for more details02/27/2014 11:26AM

QCan this solution be used in conjuction with FusionIO products that are directly on the blades? 02/27/2014 11:17AM

AThere are some use cases where a customer can use the UCS Invicta and Fusion-io. In these situations, flash presented as memory expansion for in-memory objects (via Fusion-io) would be great, where the UCS Invicta will play the “following-level” shared memory cache via our shared – and mainly deduplication – capabilities. 02/27/2014 11:27AM

QIf Invicta can be deployed without the director, can we buy it as a standalone unit? 02/27/2014 11:21AM

QHow are the relationships with existing Whiptail partners and customers changing? 02/27/2014 11:10AM

AFor former Whiptail customers a transition to Cisco for account servicing and technology partnership is complete and we're excited to welcome them to our Data Center fold. A similar integration for existing Whiptail partners is underway, and many were already Cisco partners as well. 02/27/2014 11:28AM

QHow is high availability ensured? Looks like each Invicta array is a UCS rack server where the motherboard is a single point of failure.02/27/2014 11:15AM

AHigh availability is handled by mirroring between shelves in the Scaling System architecture. 02/27/2014 11:28AM

QIs Invicta targeted at transaction processing? If so, why use dedupe? 02/27/2014 11:22AM

ADeduplication is most effective with data that contains duplicate blocks of data. If the DB or related files contains duplicate date that falls on common boundaries then you may find effective storage reduction 02/27/2014 11:29AM

QIs the NAND flash on this slide eMLC or SLC ? 02/27/2014 11:23AM

AMLC 02/27/2014 11:29AM

ACorrection. Dedupe is accomplished at the shelf level. All shelves can support dedupe 02/27/2014 11:37AM

QHow does Cisco do ScaleOut? Can a LUN traverse multiple Invicta Nodes? 02/27/2014 11:27AM

AThe answer to this is Yes you can traverse multiple nodes. That is, you have a need to present a node larger than say 19TB. This LUN could be created as large as the entire usable space although I am not sure that would be within normal practice. There are many ways to aggregate usable space with both the Server Operating Systems and the arrays02/27/2014 11:38AM

QWhat about the Accela? 02/27/2014 11:37AM

AWe renamed Accela as the UCS Invicta Scaling System02/27/2014 11:38AM

QDoes this obviate the need for the traditional PCIe-based 'bolt-on' to UCS for application acceleration? 02/27/2014 11:27AM

ANo. For customers who require in-server acceleration, without the need for scaling or pooling of the Flash resource across the larger environment, our current offerings with Fusion-IO and others will continue to be an important option. Both PCI-e card (for C-Series Rack servers) and our B-Series Blade daughtercard implementations will continue to be offered. 02/27/2014 11:38AM

QWhat sbout NFS support for vSPhere Datastores?02/27/2014 11:24AM

QDoes Invicta only work with B-series or C-series as well?02/27/2014 11:39AM

AInvicta is support on UCS B and C series. 02/27/2014 11:39AM

QAre the SSRs active/passive ? 02/27/2014 11:32AM

AThe SSRs are active/active 02/27/2014 11:40AM

QIf the Invicta OS is running on a UCS server, does that mean that commodity SSD's could be used? 02/27/2014 11:33AM

ACCisco uses only those drives which we have tested and certified after rigorous testing. The customer does not choose their own drives if that is what you are asking 02/27/2014 11:40AM

Qif it scales by adding shelves, and is accessed via Fibre Channel and/or iSCSI, is access completely transparent to end applications?02/27/2014 11:32AM

AThe scaling system has the ability to support adding additional storage nodes non-disruptively 02/27/2014 11:41AM

QDoes Invicta connect directly to the Interconnect?02/27/2014 11:35AM

AwWe will support this. Please check the UCS HCL for the details 02/27/2014 11:42AM

QCan application volumes span different shelves in an Invicta array? Or are the volumes confined to a single shelf?02/27/2014 11:31AM

AThe answer to this is Yes you can traverse multiple nodes or shelves. That is, you have a need to present a node larger than the usable TB for this shelf. A LUN could be created as large as the entire usable space of the array, although I am not sure that would be within normal practice. There are many ways to aggregate usable space with both the Server Operating Systems and the arrays 02/27/2014 11:42AM

QDo we need 2 sets of identical hardware for HA then for mirroring the data ? 02/27/2014 11:29AM

AWithin the UCS Invicta Scaling System data can be mirrored between nodes to increase data availability. Data can also be replicated between appliances and scaling systems to meet DR requirements. 02/27/2014 11:42AM

QIs integration into UCS management tools the primary advantage of Invicta over the plethora of available FC Flash arrays02/27/2014 11:35AM

AExactly. Flash is a boundary technology that already exists in both compute and storage products across the industry. Much like storage technology has historically integrated a cache layer to improve price/performance of disk, Cisco views Flash as an optimization opportunity for computing adjacent to DRAM. UCS Invicta leverages Cisco’s scalable, unified approach to computing to deliver this rapidly emerging technology to our customers in a highly optimized way. 02/27/2014 11:43AM

QWhat is the performance overhead for data deduplication?02/27/2014 11:24AM

AThis answer greatly depends on the load being driven of course, but ranges have shown roughly a 10-20% overhead for deduplication. 02/27/2014 11:43AM

QWhich grade of MLC? 02/27/2014 11:30AM

AWe use consumer grade MLC and our Operating System is built to increase the life of the drives by using intelligent write algorithms 02/27/2014 11:43AM

Qis there a whitepaper that discuss TCO saving using UCS Invicta ? 02/27/2014 11:39AM

AYes, whitepapers are available on Cisco.com02/27/2014 11:44AM

QWhat re some typical use cases for Invicta vs. whiptail?02/27/2014 11:40AM

AThe same use cases would apply. 02/27/2014 11:45AM

QHow is Invicta managed? 02/27/2014 11:28AM

AUCS Invicta can be managed through several ways. UCS Director, a proprietary graphical user interface, or through leveraging Invicta's API. 02/27/2014 11:45AM

QHow does moving application to Flash help address performance issues that are application or DB specifics ? 02/27/2014 11:39AM

AFlash eliminates the mechanical delay inherent in rotating disk. 02/27/2014 11:45AM

QYou've given different answers to the same question. Is dedupe global or is it per-shelf 02/27/2014 11:37AM

ADe-dup is global In the UCS Invicta Appliance. On the Scaling System De-dup occurs on he nodes that have data reduction active. 02/27/2014 11:46AM

QSo to fully manage UCS Invitca a customer needs UCS Manager-UCS Central and UCS Director? 02/27/2014 11:42AM

ANNo. UCS Director is an option for those customers who want to manage compute, networking, and storage from a single tool. Customers can use the standalone management tools for Invicta02/27/2014 11:48AM

QWe are retailer here in Clagary AB product "VOIP" Services home/office phones services with international calling & The problem we are facing quality and costly Looking for a better solutions/carrier I heard cisco provide best VOIP solutions so My questions is, Am I attending a right seminar? and If not whats my option Thanks02/27/2014 11:32AM

AUnfortunately no. Please contact your local Cisco sales office. They will be happy to help you. 02/27/2014 11:48AM

QWhat are the size of these, what space does it take up in the Rack? 02/27/2014 11:29AM

AOur Appliances are a self contained, 2U unit. A base Scaling System unit needs 8U and each additional shelf will require 2U in a rack. 02/27/2014 11:48AM

QWould invicta connect directly to the FI today or to the fabrics?02/27/2014 11:46AM

ABoth options will be supported. Please check the UCS HCL for details of what is supported 02/27/2014 11:49AM

QPhenomenal job answering questions, you guys. In most cases they are picked-through. You've answered great volume and were willing to accept the snarky Q's too. 02/27/2014 11:48AM

QEarlier you said that HA is provided by mirroring between Invicta shelves. Can I use RAID 0 within a shelf in that case?02/27/2014 11:43AM

AYou can mirror LUN's with a single Storage Node, however that may not make a lot of sense unless you are using establish mirror, break mirror then re-attach to another server02/27/2014 11:49AM

QCan I still start with a single appliance then move into a scale out system like Whiptail had provided previously? 02/27/2014 11:48AM

AYes, a single appliance can be added/upgraded to the Scaling System. 02/27/2014 11:50AM

QHow does Invicta play compared to hybrid storage offerings of Nimble? 02/27/2014 11:28AM

ANot everyone in the market is trying to solve the same problem. 100% flash brings a new solution to growing businesses and the UCS Invicta is designed to address any workload while providing high performance and scalability along with low total cost of ownership and the best architecture to integrate with UCS. 02/27/2014 11:50AM

Qwhat size RAID 6 groups are used? 22+2? 02/27/2014 11:42AM

AWe currently are using 24 drives and therefore the RAID6 Sets are built with 22 + 2 Parity drives 02/27/2014 11:51AM

QI have a question on HA. Do we need 2 sets of SSRs ? Or do we just need 2 sets of SSNs ? 02/27/2014 11:33AM

AA Scaling System consists of 2 SSRs and 2 SSNs. Additional SSNs can be added as needed for additional capacity and performance (up to 10 total). No additional SSRs are necessary to add SSNs. 02/27/2014 11:51AM

Qif i have invicta and other storage connected to one UCS FI; will i need the FI to work as FC switch? 02/27/2014 11:47AM

ANo. As per the UCS HCL we support a variety of different arrays connected to the FI in both NPV mode (Default) and Switching mode 02/27/2014 11:51AM

QWhat is the file system used by Invicta? 02/27/2014 11:34AM

QFor very large LUNs (That scale beyond a single shelf, how do you balance between different nodes? 02/27/2014 11:41AM

AThe UCS Invicta Scaling System enables LUNs to span multiple nodes. LUNS can be striped balancing IO performance.02/27/2014 11:53AM

QCan you turn off Dedup or it is ON all the time? 02/27/2014 11:35AM

ADeduplication is a choice at the point of sale and cannot be turned on or off. 02/27/2014 11:53AM

QIs the replication an additional cost? Can it do sync replication?02/27/2014 11:37AM

AAsynchronous replication is an additional cost. Synchronous replication is not offered at this time. 02/27/2014 11:54AM

QIs Dedupe post process or real time? 02/27/2014 11:18AM

AWe use inline, real time deduplication 02/27/2014 11:54AM

QDoes UCS Invicta support traditional Fibre Channel, or FCoE within the UCS infrastructure, or both? 02/27/2014 11:18AM

AInvicta supports FC or iSCSI targets today. 02/27/2014 11:55AM

QDoes Invicta run Garbage collection? 02/27/2014 11:41AM

AYes the UCS Invicta OS does perform garbage collection. This is a critical component of any storage media that does not do update in place. If the Invicta OS does not do garbage collection then it would rely on the onboard IO controller of the individual SSD and the onboard controller is limited in it's capacity with respect to performance 02/27/2014 11:55AM

QHow will Invicta work with my EMC storage in a vlbock design, does this devalue my EMC storage 02/27/2014 11:19AM

AThis certainly does not devalue your EMC storage. While no plans to include UCS Invicta in VBlock have been announced, VCE's evaluation of all available technology from VCE partners will continue as it has in the past. 02/27/2014 11:55AM

QDo I need a specific type of node to do data reduction or is it supported just by enabling a license? 02/27/2014 11:41AM

AAll nodes are capable of running deduplication however it needs to be a choice made at the time of purchase.02/27/2014 11:55AM

QCan dedup be purchased as an add on option after the appliance has already been purchased? 02/27/2014 11:55AM

AYes, dedupe is available as an add-on option.02/27/2014 11:56AM

Does the UCS Invicta RAID6 use dedicated parity disks or does it distribute parity among disks?

[darrwill]

Parity is distributed across all drives in UCS Invicta

Here are some other questions:

- How does mirror works in UCS Invicta? Is it LUN-level mirroring, storage node mirroring or what?

- How does snapshot works in UCS Invicta? Does it copies the data or does it copies an INODE with pointers or something else? How many snapshots supported per LUN or per node?

[darrwill]

The mirroring in UCS is done on a LUN Level.

The Snapshots are CoW and data based. At the moment in 5.0 you can have 10 Snaps per LUN and 240 Snaps per Node.

[william.caban]

With CoW snapshots, does UCS Invicta support application level consistency or just crash consistency?

Hello

Do you Know where I can find or get procedure to add a disk into an array in the invicta C3124SA 24TB

The console give us a message that the disk 24 is degraded, nex is missing, we change the disk  but the status of the console is the same, any help is welcome

Thank you
