15-sep-2009
Same hosts as last time (apr): tony gent, mark burgess; lee
Attendee: merrell lynch - 1000 vdi pcs, ratio of 30:1; not yet optimised what each vdi pc does - need 2 cpu each
- Flash drives in SAN
- controller evens out wear - max 100,000 flips for each storage cell 5y warranty 2500 iops/s - 15x speed of FC drive with 10G Ethernet, iSCSI is promising
- SAN power
- "tray of disks $1000/y to spin" - so spin down useful
[
Hitachi have an option for such power optimisation ]
- vSphere
- supports round-robin multipathing : active-active load balancing with Powerpath add-on from EMC, also need vSphere Plus
- EMC Recoverpoint
- supports HDS remote replication via journal, with rollback;
can recover any point in time, read/write access to that image, mounted to any san host; from windows can bookmark points of consistency via vss;
no need for backup agents on app host - just backup the snapshots;
falconstore has similar technology; use clariion Splitter for writes (each write sent to two places) or a standalone box or achieve in fabric switch or in the clariion array
- vCentre replication manager
- automated recovery plans; central mgmt.; replaces ad-hoc scripts and knowledge; need vCentre at both sites; bi-directional;
vstorage APIs include site recovery mgr, which hosts RM; hds support ready yet?
site RM licence is per cpu socket on esx host holding protected machines at protected site; vmware may change licensing to destination environment;
reversal is somewhat tedious - re-do plan in reverse - simpler method is in roadmap
- Avamar
- Hardware appliance or VMware virtual one for deduplication at source to disk array good for satellite sites - licensed by backend capacity; replaces trad. backup; can replicate to another avamar
- Networker
- auto-discovery of VMs; login to vCentre; multiple vCentres supported;
licence now adapted for virtual env. - by esx host 'virtual edition client lic.';
integrates w/avamar; networker mgmt console manages avamar; single agent - generic microsoft - via vss - exch sharepoint sql DMP; policy-based snapshot mgmt - powersnap modules; ?hds support; off-host live backup to disk/tape;
network data mgmt protocol - especially for NAS; networker fast start bundle - 20 clients
- vSphere 4
- esx 3.5 review:
- esx 3i faster startup; is strategic route; console in vmdk
- auto discovery of physical servers
- storage vmotion for FC SANs via cli - plug-ins unreliable
- VMware Consolidated Backup now in VM (not physical server)
- windows VSS quiescing
- esx V4:
- Intel hardware-assist cpu & mem virt - g6 has both; g5 has cpu only
- vmxnet3 improved networking; need to enable, for v. intensive needs
- vmdirectpath io - passthough to vm - eg previously difficult-to-virtualise cases eg voip
- paravirtual. scsi driver, is add-on for high io env - tested 364K iops, 1000 disks
- alerts on many more things e.g. snapshots
- DPM - dynamic power mgmt
- monitors cpu & mem load, not disk or net
uses wake on lan to start ESX hosts when needed; shuts them down when not needed
also slow-down server mode - intel speed step
- vStorage thin provisioning
- eliminate never-used space (e.g. alloc. 30G sys disk but only use 10G)
- vStorage APIs for data protection
- replaces VMware Consolidated Backup; uses change-block tracking
- vSphere data recovery
- not physical servers, "poor man's Avamar"
agentless disk-based backup, using APIs & change-block tracking; via vcentre
vm or file-level restore
no tape-out
- vNetwork distributed switch
- single virtual switch across hosts; need Enterprise Plus licence
also 3rd party vswitch software too; can then hand mgmt to institutional network (cisco) team - need cisco add-on product
- vmware FT
- 1ary - 2ary plus link : vlockstep technology - replay 1ary events on 2ary; 2ary is offline to storage & net; zero downtime and data loss; new 2ary created upon failover; only 1 vcpu supported
- vmsafe
- API for 3rd party sec - eg sophos, client firewall to esx level; none on market yet; will be big for VDI
- vshield zones
- packet filtering, firewall, zones; vm appliance to manage; for PCI (credit card) compliance etc; zones can span esx hosts
- vApp
- self-describing apps - enable automated SLA mgmt.
- vCentre
- many more alarms, better analysis;
vcentre orchestrator - workflow; host profiles - reference configs - needs Enterprise Plus licence; linked mode - shared roles & lic. info; perl scriptings via cli; also powercli (like windows powershell)
- vcentre Appspeed - they will send out presentation
- vcentre chargeback - they will send out presentation
- virtualisation for exch & sql - they will send out presentation
- vcentre chargeback - they will send out presentation
Preview of VMware developments
- long-distance vmotion
- vmware view 4 - by end of year:
- rdp / ica
- vmware TRUE PCoIP from teradici - expected to best ICA
- - end-to-end s/w implementation, optional h/w accel.
- - announced year ago, just starting demos
- wyse building teradici chips into clients
- RTO virtual user profiles [ie competitor to SmartStart]
- - licenced to vmware, uses MS profiles, no backend infrastructure
- - bundled w/ vmware View 4
- vmware TRUE PCoIP from teradici - expected to best ICA
- client virtualisation platform
- baremetal hyper-visor - bare metal for desktops/laptops; works with intel vPro; fully virtualises h/w - vista/7 aero desktop; runs online & offline Vmware View desktops; single VM at first
- site recov mgr
- out q409; many-to-one failover - outlying datacentres to centre
- capacityIQ
- q409; when run out of capacity? what if? spot underused resources
- avamar 5
- vsphere 4 support; use change-block tracking feature; incremental block-based vmdk backup
- FAST V2
- sub-LUN optimisation, positioning in store tiers (tier 1: solid/flash; tier 2: FC disks/SAS; tier 3: SATA)
- array integration VAAI
- misc storage optimisations e.g. direct array ops; e.g. lun state alarms
